 Ideally you would use PKG_CHECK_MODULES in your configure.ac file.

Subject: [PATCH 002/153] Remove dependency on glibmm and don't use
 Glib::ustring

For now, the API uses an xmlpp::ustring where it previously used
Glib::ustring.

     <para>The libxml++ API takes, and gives, strings in the UTF-8 Unicode encoding, which can support all known languages and locales. This choice was made because, of the encodings that have this capability, UTF-8 is the most commonly accepted choice. UTF-8 is a multi-byte encoding, meaning that some characters use more than 1 byte. But for compatibility, old-fashioned 7-bit ASCII strings are unchanged when encoded as UTF-8, and UTF-8 strings do not contain null bytes which would cause old code to misjudge the number of bytes. For these reasons, you can store a UTF-8 string in a std::string object. However, the std::string API will operate on that string in terms of bytes, instead of characters.</para>
-    <para>Because Standard C++ has no string class that can fully handle UTF-8, libxml++ uses the Glib::ustring class from the glibmm library. Glib::ustring has almost exactly the same API as std::string, but methods such as length() and operator[] deal with whole UTF-8 characters rather than raw bytes.</para>
-    <para>There are implicit conversions between std::string and Glib::ustring, so you can use std::string wherever you see a Glib::ustring in the API, if you really don't care about any locale other than English. However, that is unlikely in today's connected world.</para>
-    <para>glibmm also provides useful API to convert between encodings and locales.</para>
+    <para>The libxml++ API indicates when a string should be provided as UTF-8, or will be provided as UTF-8, by using the xmlpp::ustring type alias. However, this is really just a std::string, whose operator[] and size() consider bytes, not characters.</para>

-    <para>All of the parsers may parse XML documents directly from disk, a string, or a C++ std::istream. Although the libxml++ API uses only Glib::ustring, and therefore the UTF-8 encoding, libxml++ can parse documents in any encoding, converting to UTF-8 automatically.

+  There is also a libxml++-4-0 branch for the libxml++-4.0 ABI,

+* Build: Remove dependency on glibmm and don't use Glib::ustring
+  For now, the API uses an xmlpp::ustring alias of std::string
+  where it previously used Glib::ustring.

 3.9.1 (unstable):
 
 * Change ABI name to libxml++-4.0

Subject: [PATCH 005/153] Rename MSVC_Net2010 to MSVC_NMake

This initiates the move from the Visual Studio project files to using NMake
Makefiles, so that we reduce the likelihood of the MSVC build files becoming
outdated, by sharing the autotools build files' source listings.

Subject: [PATCH 009/153] gendef.cc: Skip symbols implemented inline

Like in the case of gtkmm, some symbols were implemented inline in the CRT on
Visual Studio 2015+ (UCRT), so we don't want to put them in our .def file,
otherwise linking will fail.

Subject: [PATCH 010/153] Add NMake Makefiles

This adds a set of NMake Makefiles that can be used to build libxml++,
which will replace the Visual Studio 2010(!) projects that reside in the
repository.

To be consistent with the rest of the -mm stack that we build with Visual
Studio, we will need to separate the output filenames for the resulting .lib
and .dll files for Visual Studio 2017 and 2019.  A NMake Makefile build option
"USE_COMPAT_LIBS" is added if building 'xml++-vc150-x_y.[dll|lib] is still desired.

Note that this branch does not rely on glibmm nor libsigc++, so linking against
libxml2 built with an older Visual Studio version should work properly, if
libxml2 is built with Visual Studio 2015 or later, but again, we are enforcing
the Visual Studio toolset versioning policy by default for consistency's sake.

Update instructions for building since we moved to using NMake
Makefiles, and let people know that the same compiler version is
recommended for building libxml++.

-Building libxml++ with Visual Studio 2010
-
-* You will need Visual Studio 2010 (MSVC 10.0).  See the MSVC_Net2005/ folder if you want to build libxml++ using Visual Studio .NET 2005 (MSVC 8.0) or the MSVC_Net2008 folder if you want to build libxml++ using Visual Studio .NET 2008 (MSVC 9.0). Earlier versions of the compiler, including 6.0, 7.0 and 7.1 will not work.  
-* Install the latest Win32 GTK+ Development files from ftp://ftp.gnome.org/pub/GNOME/binaries/win32/gtk+/
-* Build libsigc++ 2.0.6 and glibmm from source
-* Add GTK+, libsigc++ and glibmm to the include and lib paths in Visual Studio. 
-* Load the MSVC_NMake/libxml++.sln solution. 
-* Build the entire solution.  Run the tests.

+Building libxml++ with Visual Studio 2017 or later
+
+* You will need Visual Studio 2017 (MSVC 15.7) or later, as C++-17 is required and only 15.7 or later had
+  adequate C++-17 support
+* Install libxml2 from https://xmlsoft.org/, either via Windows binaries or building from source.  It is
+  strongly recommended, if building libxml2 from source, that Visual Studio 2015 or later is used
+* Add libxml2 to the include and lib paths in Visual Studio.
+* Run `nmake /f Makefile.vc CFG=[debug|release]` to buiild libxml++.  Run `nmake /f Makefile.vc` without the
+  `CFG=[debug|release] flag to see which options are supported by the NMake Makefiles

Subject: [PATCH 015/153] libxml++config.h.in: Re-organize LIBXMLPP_API

We want to set LIBXMLPP_API to the following:

* __declspec(dllexport) when building the libxml++ DLL on Windows
* __declspec(dllimport) when using the libxml++ DLL on Windows
* <nothing> if building/using a static or a non-Windows libxml++ build

Subject: [PATCH 016/153] NMake Makefiles: Stop using gendef

This updates the NMake Makefiles to stop building and using the gendef tool,
since we are now using compiler directives to export symbols for libxml++
builds.

Since this branch did not have official and working Visual Studio build files,
and it is not API/ABI compatible with the libxml++-2.6 series, gendef.cc will
be dropped in the next commit

+# Building
+
+Whenever possible, you should use the official binary packages approved by the
+supplier of your operating system, such as your Linux distribution.
+
+## Building on Windows
+
+See MSVC_NMake/README
+
+## Building from a release tarball
+
+Extract the tarball and go to the extracted directory:
+  $ tar xf libxml++-@LIBXMLXX_VERSION@.tar.xz
+  $ cd libxml++-@LIBXMLXX_VERSION@
+
+It's easiest to build with Meson, if the tarball was made with Meson,
+and to build with Autotools, if the tarball was made with Autotools.
+Then you don't have to use maintainer-mode.
+
+How do you know how the tarball was made? If it was made with Meson,
+it contains files in untracked/docs/ and other subdirectories
+of untracked/.
+
+### Building from a tarball with Meson
+
+Don't call the builddir 'build'. There is a directory called 'build' with
+files used by Autotools.
+
+  $ meson --prefix /some_directory --libdir lib your_builddir .
+  $ cd your_builddir
+
+If the tarball was made with Autotools, you must enable maintainer-mode:
+  $ meson configure -Dmaintainer-mode=true
+
+Then, regardless of how the tarball was made:
+  $ ninja
+  $ ninja install
+You can run the tests like so:
+  $ ninja test
+
+### Building from a tarball with Autotools
+
+If the tarball was made with Autotools:
+  $ ./configure --prefix=/some_directory
+If the tarball was made with Meson, you must enable maintainer-mode:
+  $ ./autogen.sh --prefix=/some_directory
+
+Then, regardless of how the tarball was made:
+  $ make
+  $ make install
+You can build the examples and tests, and run the tests, like so:
+  $ make check
+
+## Building from git
+
+Building from git can be difficult so you should prefer building from
+a release tarball unless you need to work on the libxml++ code itself.
+
+jhbuild can be a good help
+  https://gitlab.gnome.org/GNOME/jhbuild
+  https://wiki.gnome.org/Projects/Jhbuild
+
+### Building from git with Meson
+
+Maintainer-mode is enabled by default when you build from a git clone.
+
+Don't call the builddir 'build'. There is a directory called 'build' with
+files used by Autotools.
+
+  $ meson --prefix /some_directory --libdir lib your_builddir .

Update the rules so that we won't attempt to unnecessarily generate

generate them with the version info if generating them becomes necessary.

Also streamline this process so that it will be part of the 'all' target.

Subject: [PATCH 025/153] NMake Makefiles: Use Meson-style DLL and .lib naming
 if requested

To make things more consistent and less prone to confusion, if 'USE_MESON_LIBS'
is specified in the NMake command line, build the DLLs and .lib's that are
named like the Meson counterparts.  Binaries built with Meson+Visual Studio
and the ones that are built via NMake using 'USE_MESON_LIBS' are
interchangeable, provided that they are built with the same Visual Studio
version.

Also, introduce the 'USE_COMPAT_LIBS' option as well, so that we are more
consistent with the other active branches of libxml++.

+## ABI Versions
+
+There are several ABI (Application Binary Interface) versions of libxml++.
+They can be installed in parallel.
+
+libxml++-2.6: Old ABI, not recommended for new applications. Uses Glib::ustring from the glibmm-2.4 ABI.
+
+libxml++-3.0: Uses Glib::ustring from the glibmm-2.4 ABI, therefore has methods that handle UTF-8 characters rather than raw bytes.
+
+libxml++-4.0: Uses Glib::ustring from the newer glibmm-2.68 ABI, therefore has methods that handle UTF-8 characters rather than raw bytes.
+
+libxml++-5.0: Does not depend on glibmm, is not as good at handling UTF-8 strings, but has fewer dependencies.

 subproject

mm-common can be a subproject of libxml++.
libxml2 can't be a subproject because it can't be built with Meson.

Subject: [PATCH 037/153] Clean up Visual Studio build files

We no longer need to ignore warnings C4251, C4273 and C4275, and we will
now use /EHsc, so we also no longer need to ignore warning C4530.

Subject: [PATCH 038/153] Fix build as subproject without building
 documentation

* meson.build: If mm-common-get is not found in maintainer-mode
with 'required: false', try with 'required: true'.
Don't try to use tag_file, if documentation is not built.
* docs/reference/meson.build: Don't use variables from modules
that don't define doxytagfile. These are subprojects that don't build
their documentation.

But for compatibility, old-fashioned 7-bit ASCII strings are unchanged when encoded as UTF-8, and UTF-8 strings do not contain null bytes which would cause old code to misjudge the number of bytes.

     <para>The libxml++ API takes, and gives, strings in the UTF-8 Unicode encoding, which can support all known languages and locales. This choice was made because, of the encodings that have this capability, UTF-8 is the most commonly accepted choice. UTF-8 is a multi-byte encoding, meaning that some characters use more than 1 byte. But for compatibility, old-fashioned 7-bit ASCII strings are unchanged when encoded as UTF-8, and UTF-8 strings do not contain null bytes which would cause old code to misjudge the number of bytes. For these reasons, you can store a UTF-8 string in a std::string object. However, the std::string API will operate on that string in terms of bytes, instead of characters.</para>
     <para>The libxml++ API indicates when a string should be provided as UTF-8, or will be provided as UTF-8, by using the xmlpp::ustring type alias. However, this is really just a std::string, whose operator[] and size() consider bytes, not characters.</para>

     <para>To use libxml++ in your application, you must tell the compiler where to find the include headers and where to find the libxml++ library. libxml++ provides a pkg-config .pc file to make this easy. For instance, the following command will provide the necessary compiler options:

     <para>Like the underlying libxml2 library, libxml++ allows the use of 3 parsers, depending on your needs - the DOM, SAX, and TextReader parsers. The relative advantages and behaviour of these parsers will be explained here.</para>
     <para>All of the parsers may parse XML documents directly from disk, a string, or a C++ std::istream. Although the libxml++ API uses only xmlpp::ustring, indicating the UTF-8 encoding, libxml++ can parse documents in any encoding, converting to UTF-8 automatically. This conversion will not lose any information because UTF-8 can represent any locale.</para>
-    <para>Remember that white space is usually significant in XML documents, so the parsers might provide unexpected text nodes that contain only spaces and new lines. The parser does not know whether you care about these text nodes, but your application may choose to ignore them.</para>

       <para>The DOM (Document Object Model) parser parses the whole document at once and stores the structure in memory, available via <methodname>DomParser::get_document()</methodname>. With methods such as <methodname>Document::get_root_node()</methodname> and <methodname>Node::get_children()</methodname>, you may then navigate into the hierarchy of XML nodes without restriction, jumping forwards or backwards in the document based on the information that you encounter. Therefore the DOM parser uses a relatively large amount of memory.</para>

We can save people from a large download and a large disk footprint for the
MFC/ATL items as those items are only optionally installed for later
(2017+) Visual Studio versions, by including winresrc.h instead, which
is always present in a Visual Studio installation.

Subject: [PATCH 056/153] meson.build: Specify 'check' option in run_command()

The default value will be changed in future Meson releases.

Don't use deprecated python3.path() and execute(..., gui_app: ...).
Let import('python').find_installation() always find the python
installation used to run Meson.
Don't distribute .github/.

Subject: [PATCH 062/153] Meson: Some minor cleanups

We don't actually need to check for the /wd4828 compiler flag here, so stop
checking for that.

Move the '/utf-8' compiler flag check to be together with the other warning-
related compiler flag checks.

 flags

Add a short description for each of the warning-related compiler flags that we
apply globally.

Also, apply '/wd4267' only when we are building a 64-bit build, as that warning
should only be related to 64-bit builds.

Subject: [PATCH 066/153] parsers: Avoid std::getline for istream inputs

For streambuf implementations that can't set a public get area, getline falls
back to a character-by-character implementation. Instead we can pass the stream
to xmlCreateIOParserCtxt(). This simplifies the parse stream methods and brings
them nearly identical to the other parse methods.

From meson 0.51.0, cpp_eh defaults to /EHsc on windows. Passing it to
add_program_arguments() means downstream projects using cpp_eh=a will get
warnings.

 msvc_recommended_pragmas.h

We don't depend on glibmm for libxml++-5.x, so drop the forced include.  Mishap
when migrating the NMake Makefiles for libxml++-4.x, which does depend on

Subject: [PATCH 086/153] NMake Makefiles: Make things more configurable

Add the INCLUDEDIR and LIBDIR options, so that we can set where we find
dependent headers and libraries, if they are not in %INCLUDE% and/or %LIB%
and are not in $(PREFIX)\include and $(PREFIX)\lib.

Also mention about the PREFIX and PERL options, so that one can use them when
necessary.

Subject: [PATCH 093/153] exceptions/exception.h: Try fixing linking on MinGW
 (#46)

Using the xmlpp::exception class may lead to a linker error on its
vtable on MinGW, unless the whole class is exported, but we also want to
avoid exporting that whole class under Visual Studio, so that we can
avoid having the built DLL/import library being tied to a particular STL
version, so define macros to accomdate such situations and apply it to
the xmlpp::exception class.

This should not affect the ABI stability on Visual Studio builds.

Fixes: https://github.com/libxmlplusplus/libxmlplusplus/issues/45

Apparently it's not enough to decorate a class with
__attribute__((visibility("default"))), so also decorate it with
__declspec(dllexport), via macros as needed.

Pointed out by Kjell in PR #46.

Subject: [PATCH 100/153] Meson build: Don't copy files with configure_file()

It's deprecated since Meson 0.64. The replacement, fs.copyfile(),
is not useful here. It only copies from the source directory to
the build directory.

* libxml++/parsers/parser.[cc|h]: Deprecate
callback_[parser|validity]_[error|warning](), enum MsgType,
callback_error_or_warning(MsgType...). Add ParserCallbackCFuncType,
get_callback_[parser|validity]_[error|warning]_cfunc(),
callback_error_or_warning(bool, bool...).
Use local 'extern "C"' callback functions.
* libxml++/validators/validator.[cc|h]: Deprecate
callback_validity_[error|warning](). Add ValidatorCallbackCFuncType,
get_callback_validity_[error|warning]_cfunc(),
callback_error_or_warning(bool...).
Use local 'extern "C"' callback functions.
* libxml++/validators/dtdvalidator.cc:
* libxml++/validators/relaxngvalidator.cc:
* libxml++/validators/xsdvalidator.cc:
Use get_callback_validity_[error|warning]_cfunc().

Code that mixes up C linkage and C++ linkage has undefined behavior.
Most compilers make no difference between C and C++ linkage, so it
has not been an issue so far. But see issue glibmm#1.

Subject: [PATCH 109/153] Meson: Cleanup and fix libxml2 dep search

Use CMake to help us find libxml2, in addition to using pkg-config, as
CMake actually looks up libxml2 for us using the headers in %INCLUDE%
and the libraries in %LIB% in a more comprehensive way, so we don't need
to reinvent the wheel.

Since we use Meson 0.60.0 or later, we can use the CMake libxml2
dependency name together with libxml-2.0.pc to find libxml2 in one
single call.

Also update the libxml2 CMake subproject by using CMake to find ICU and
liblzma in the same manner, and ensure that we have the correct
libxml2 .lib in the resulting pkg-config file for libxml++.

Subject: [PATCH 110/153] Update Visual Studo build docs

Update the Visual Studio build documentation by:

* Using MarkDown format, to make things easier for the eye, and use UNIX
  line endings.
* Update information as appropriate, especially on Meson builds.

+Building libxml++ with Visual Studio 2017 or later
+-
+
+* You will need Visual Studio 2017 (MSVC 15.7.x) or later, as `C++-17` is
+required and only 15.7.x or later had adequate `C++-17` support.
+* Install libxml2 from https://xmlsoft.org/, either via Windows binaries or
+building from source, using NMake or CMake.  It is strongly recommended, if
+building libxml2 from source, that Visual Studio 2015 or later is used.
+* Add libxml2's include path to `%INCLUDE%` and its library path to `%LIB%`, or
+placing the dependencies like the following:
+```
+$(some_dir_1)\include
+   |
+   --libxml2\libxml\*.h
+   |
+   --(headers of libraries libxml2 depends on, such as ZLib, liblzma...)
+
+$(some_dir_2)\lib
+   |
+   --libxml2.lib
+   |
+   --(.lib's of libraries that libxml2 depends on, such as ZLib, liblzma)
+```
+* You need libxml2's DLL and all of its dependent DLLs in `%PATH%` if linking
+against a DLL build of libxml2 in order to run the tests.
+
+* Notice that for the built DLL and .lib the Visual Studio version is no
+longer `vc$(VSVER)0`, but is named like the following (Visual Studio version),
+to follow what is done in other C++ libraries such as Boost (use
+`-Dmsvc14x-parallel-installable=false` to the Meson options or pass
+`USE_COMPAT_LIBS=1` in the NMake commandline to override, recommended only if
+rebuilding items using libxml++ is inconvenient):
+  * NMake:
+    * 2017: `VSVER=15`, `xml++-vc141-5_0.[dll|pdb|lib]`
+    * 2019: `VSVER=16`, `xml++-vc142-5_0.[dll|pdb|lib]`
+    * 2022: `VSVER=17`, `xml++-vc143-5_0.[dll|pdb|lib]`
+  * Meson:
+    * 2017: `VSVER=15`, `xml++-vc141-5.0-1[dll|pdb]`, `xml++-vc141-5.0.lib`
+    * 2019: `VSVER=16`, `xml++-vc142-5.0-1[dll|pdb]`, `xml++-vc142-5.0.lib`
+    * 2022: `VSVER=17`, `xml++-vc143-5.0-1[dll|pdb]`, `xml++-vc143-5.0.lib`
+
+
+### NMake Builds
+* Note that `$(Platform)` refers to the following:
+  * `$(Platform)`
+    * AMD64/x86_64/x64: `x64`
+    * ARM64/aarch64: `arm64`
+    * x86/i686: `Win32`
+
+* Run the following:
+```
+cd $(srcroot)\MSVC_NMake
+# Run "nmake /f Makefile.vc" to see to see what options are supported by
+# the NMake Makefiles
+# INCLUDEDIR is by default $(PREFIX)\include, and LIBDIR is by default
+# $(PREFIX)\lib. PREFIX is by default $(srcroot)\..\vs$(VSVER\$(Platform).
+# $(some_dir_1) and $(some_dir_2) refer to the sample layout listed above.
+
+nmake /f Makefile.vc CFG=[debug|release] [PREFIX=...] [INCLUDEDIR=$(some_dir_1)\include] [LIBDIR=$(some_dir_2)\lib]
+```
+* The following targets are supported (only DLL builds are supported out of the
+box with the NMake Makefiles):
+  * `all`, `libxmlxx_examples` (or nothing passed in): The libxml++ library as
+a DLL with the example programs
+  * `tests`: The libxml++ library as a DLL with the test programs
+
+### Meson builds
+Please also see [README.md](../README.md) for further details.
+
+For Visual Studio builds, it is also recommended that CMake is installed and can
+be found in `%PATH%`, so that it can help with finding an installed libxml2, or
+build libxml2 alongside with libxml++ if it is not previously installed. If
+libxml2 is installed, you will most probably need to add its include directory
+to `%INCLUDE%` and its library path to `%LIB%`, as described earlier.

 # libxml++
+C++ interface to libxml2 and XML files.
+
+# Introduction
+
 libxml++ (a.k.a. libxmlplusplus) provides a C++ interface to XML files. It uses
 libxml2 to access the XML files, and in order to configure libxml++ you must
 have both libxml2 and pkg-config installed.
 
-To get the latest version of libxml++, see the
-[libxml++ web site](https://libxmlplusplus.github.io/libxmlplusplus/)
+libxml++-2.6, libxml++-3.0, libxml++-4.0 and libxml++-5.0 are different
+parallel-installable ABIs. This file describes libxml++-5.0.
 
 See the examples directory for example code.
 
-Use pkg-config to discover the necessary include and linker arguments. For instance,
+Use pkg-config to discover the necessary include and linker arguments.
+For instance,
 ```
   pkg-config libxml++-5.0 --cflags --libs
 ```
 If you build with Autotools, ideally you would use PKG_CHECK_MODULES in your
 configure.ac file.

 ## ABI Versions
 
 There are several ABI (Application Binary Interface) versions of libxml++.
 They can be installed in parallel.
 
-libxml++-2.6: Old ABI, not recommended for new applications. Uses Glib::ustring from the glibmm-2.4 ABI.
+- libxml++-2.6: Old ABI, not recommended for new applications.
+  Uses Glib::ustring from the glibmm-2.4 ABI.
 
-libxml++-3.0: Uses Glib::ustring from the glibmm-2.4 ABI, therefore has methods that handle UTF-8 characters rather than raw bytes.
+- libxml++-3.0: Uses Glib::ustring from the glibmm-2.4 ABI,
+  therefore has methods that handle UTF-8 characters rather than raw bytes.
 
-libxml++-4.0: Uses Glib::ustring from the newer glibmm-2.68 ABI, therefore has methods that handle UTF-8 characters rather than raw bytes.
+- libxml++-4.0: Uses Glib::ustring from the newer glibmm-2.68 ABI,
+  therefore has methods that handle UTF-8 characters rather than raw bytes.
 
-libxml++-5.0: Does not depend on glibmm, is not as good at handling UTF-8 strings, but has fewer dependencies.
+- libxml++-5.0: Does not depend on glibmm, is not as good at handling UTF-8 strings,
+  has fewer dependencies.
+
+The APIs of libxml++-3.0, libxml++-4.0 and libxml++-5.0 are very similar.
+The only significant difference is that libxml++-5.0 uses xmlpp::ustring
+instead of Glib::ustring.
+
+In a new application, choose between libxml++-4.0 with UTF-8 support and libxml++-5.0
+with fewer dependencies. Choose libxml++-3.0 only if you want UTF-8 support but
+don't have access to the newer glibmm-2.68 ABI (glibmm version 2.68.0 or higher).

 Whenever possible, you should use the official binary packages approved by the
 supplier of your operating system, such as your Linux distribution.
 
+## Building the documentation
+
+The reference documentaion is built with Doxygen.
+
+The manual is a DocBook 5.0 document. These packages are recommended when building
+the manual (can have other names in other distros):
+ - docbook5-xml (Ubuntu and Debian) or docbook5-schemas (Fedora)
+ - docbook-xsl (Ubuntu and Debian) or docbook-style-xsl (Fedora)
+
+It may be possible to build without these packages, but it will be slow and error prone.
+The `xmllint` command is told to read files from http://docbook.org.
+The `xsltproc` command is told to read files from http://docbook.sourceforge.net.
+The commands first search for local copies of those files. If local copies exist
+and are installed at expected locations, the commands make no network accesses.

Subject: [PATCH 122/153] Meson build: Don't require the 'dot' command

Make it possible to build documentation without the dot command.
Set the HAVE_DOT option in Doxyfile during configuration.
In Autotools builds it's still unconditionally YES.
The inheritance diagrams don't look as nice without the dot
command from the GraphViz package.

See https://github.com/libsigcplusplus/libsigcplusplus/issues/98

Subject: [PATCH 143/153] TextReader: xmlStructuredErrorFunc() changed in
 libxml2 2.12.0

Before 2.12.0: typedef void (*xmlStructuredErrorFunc) (void *userData, xmlError *error);
Since 2.12.0: typedef void (*xmlStructuredErrorFunc) (void *userData, const xmlError *error);

* libxml++/parsers/textreader.cc: The declaration of c_callback_error()
must fit the libxml2 version being compiled with. As it's a function with
C linkage, its name is not mangled. It's not an ABI break.

Subject: [PATCH 144/153] TextReader: Add methods that return
 std::optional<xmlpp::ustring>

Add read_inner_xml2(), read_outer_xml2(), read_string2(), get_base_uri2(),
get_local_name2(), get_name2(), get_namespace_uri2(), get_prefix2(),
get_value2(), get_xml_lang2(), get_attribute2() (3 overloaded ones),
lookup_namespace2(). An empty string is not necessarily the same as no string.
Deprecate the corresponding functions that return xmlpp::ustring.
Fixes #71

From: Kjell Ahlstedt <kjellahlstedt@gmail.com>
Date: Sun, 8 Dec 2024 10:28:58 +0100
Subject: [PATCH 145/153] Add more methods that return
 std::optional<xmlpp::ustring>

* libxml++/attribute.[cc|h]:
* libxml++/attributedeclaration.[cc|h]:
* libxml++/attributenode.[cc|h]: Add get_value2().
* libxml++/document.[cc|h]: Add get_encoding2()
* libxml++/dtd.[cc|h]: Add get_external_id2(), get_name2(), get_system_id2().
* libxml++/nodes/contentnode.[cc|h]: Add get_content2().
* libxml++/nodes/element.[cc|h]: Add get_attribute_value2().
* libxml++/nodes/entitydeclaration.[cc|h]:
* libxml++/nodes/entityreference.[cc|h]: Add get_original_text2(),
get_resolved_text2().
* libxml++/nodes/node.[cc|h]: Add get_name2(), get_namespace_prefix2(),
get_namespace_uri2(), get_path2().

Deprecate the corresponding methods that return xmlpp::ustring. See #71

* examples/dom_build/main.cc:
* examples/dom_parse_entities/main.cc:
* examples/dom_parser/main.cc:
* examples/dom_parser_raw/main.cc:
* examples/dom_xinclude/main.cc:
* examples/dom_xpath/main.cc:
* examples/sax_parser_build_dom/main.cc:
* tests/istream_ioparser/main.cc: Use the new methods instead of
the deprecated ones.

-
-	Node: Fix memory problems in import_node().
-
-	* libxml++/nodes/node.[h|cc]: Return added_node instead of imported_node,
-	which libxml2 may delete. Delete the C++ wrapper of a deleted attribute node.
-	* examples/import_node/example[1|2].xml:
-	* examples/import_node/main.cc: Import attributes and a text node which is
-	merged with an existing text node. Bug #672992.

-2.35.2:
-
-2012-03-21  Murray Cumming  <murrayc@murrayc.com>
-
-	Fix a warning found by clang++
-
-	* libxml++/parsers/textreader.h: PropertyReader is a class, not
-	a struct.
-
-2012-03-20  Murray Cumming  <murrayc@murrayc.com>
-
-	Remove the --disable-api-exceptions configure option.
-
-	And remove the #ifdefs and #else blocks from the code.
-	This is not used by anybody now, as far as I know, so this makes the
-	code easier to maintain.
-
-2012-03-20  Murray Cumming  <murrayc@murrayc.com>
-
-	A fix for the previous commit.
-
-	* libxml++/nodes/node.cc: get_first_child() const: Use the name 
-	parameter.
-
-2012-03-19  Murray Cumming  <murrayc@murrayc.com>
-
-	Node: Add get_first_child().
-
-	* libxml++/nodes/node.[h|cc]: This is like get_children(),
-	but it returns only the first node, optionally returning
-	the first one with a certain name.
-	Based on a patch by Ilya Murav'jov in bug #648125 .
-
-2.35.1:
-
-2012-02-15  Kjell Ahlstedt  <kjell.ahlstedt@bredband.net>

-	* libxml++/nodes/element.[h|cc]: get_attribute(): Add description. Don't use
-	xmlHasProp(), it ignores namespace.
-	* libxml++/nodes/node.cc: get_namespace_prefix(), get_namespace_uri(),
-	set_namespace(), create_wrapper(): Add code for XML_ATTRIBUTE_DECL.

-	* libxml++/nodes/entityreference.h: Improve the description of
-	get_resolved_text() and get_original_text().
-	* libxml++/nodes/node.cc: get_namespace_prefix() and get_namespace_uri():
-	XML_ENTITY_DECL has no namespace. Don't try to find it.
-	create_wrapper(): Create an EntityDeclaration when type == XML_ENTITY_DECL.
-	free_wrappers(): Don't walk the child list when type == XML_ENTITY_REF_NODE.

-	processing instructions to the built xml file.
-	* examples/dom_parse_entities/example.dtd: Make it compatible with example.xml.
-	* examples/dom_parse_entities/example.xml: Add an entity definition that

-2012-02-15  Kjell Ahlstedt  <kjell.ahlstedt@bredband.net>
-
-	Add some files to .gitignore.
-

-	Bug #304020.
-
-2012-02-10  Kjell Ahlstedt  <kjell.ahlstedt@bredband.net>
-
-	Make the schema validation example program work with no arguments.
-
-	* examples/schemavalidation/main.cc: Correct the test for number of arguments.
-
-2012-01-30  Kjell Ahlstedt  <kjell.ahlstedt@bredband.net>
-
-	Parser: Throw more detailed error messages.
-
-	* examples/dom_parser/main.cc: Add command parameters -v -e -t.
-	* libxml++/exceptions/exception.[h|cc]: Add format_xml_error() and
-	format_xml_parser_error().
-	* libxml++/parsers/domparser.cc: Call format_xml_error() and
-	format_xml_parser_error() to get more detailed messages in exceptions.
-	* libxml++/parsers/parser.[h|cc]: Add [set|get]_throw_messages() and (local in
-	.cc until ABI can be broken) on_parser_[error|warning](). Bug #304020.
-
-2012-01-30  Murray Cumming  <murrayc@murrayc.com>
-
-	Document: Make the Document(xmlDoc*) constructor protected.
-
-	* libxml++/document.h: This was requested in bug #668980 (A. Pignotti).
-
-2011-09-09  Murray Cumming  <murrayc@murrayc.com>
-
-	Document: write_to_*(): Make sure that we write UTF-8 out.
-
-	* libxml++/document.cc: Because the xmlDocDump*() functions use some other 
-	encoding if you specify NULL, causing errors such as:
-	xmlEscapeEntities : char out of range
-
-2.34.2:
-
-2011-09-06  Mathias Lorente  <mathias.lorente@free.fr>
-
-	Node::create_new_child_node(): Use the default namespace if none is specified.
-
-	* libxml++/nodes/node.cc: This is better than just ignoring it.
-	Bug #656110
-
-2011-07-20  Murray Cumming  <murrayc@murrayc.com>
-
-	ContentNode::get_content(): Fix a documentation typo.
-
-	* libxml++/nodes/contentnode.h: Mention &gt; instead of &qt (a q 
-	instead of a g, and no ;.).
-
-2011-07-20  Mathias Lorente  <mathias.lorente@free.fr>
-
-	Add Element::add_child_cdata().
-
-	* libxml++/nodes/element.[h|cc]: Add add_child_cdata(), using 
-	xmlNewCDataBlock(), like the existing add_child_text().
-	* examples/sax_parser_build_dom/example.xml:
-	* examples/sax_parser_build_dom/svgparser.[h|cc]: Use the new API.
-
-2.34.1:
-
-2011-04-17  Murray Cumming  <murrayc@murrayc.com>
-
-	Fix distcheck.
-
-	* Makefile.am: Specify the full path to docbook-customisation.xsl,
-	which is apparently necessary with the autotools that I have here.
-
-2011-04-17  Murray Cumming  <murrayc@murrayc.com>
-
-	Fix the build with --enable-warnings=fatal.
-
-	* configure.ac: Use -no-long-long to avoid an (apparently new) compiler
-	warning about long long not being supported by C++98. glibmm already had
-	this option.
-
-2011-04-17  Murray Cumming  <murrayc@murrayc.com>
-
-	Do not require mm-common during the tarball build.
-
-	* configure.ac: Add a MM_CONFIG_DOCTOOL_DIR() call.
-
-2.34.0:
-
-2011-02-24  Murray Cumming  <murrayc@murrayc.com>
-
-	Fix the build with the changed linker behaviour on Ubuntu Natty.
-
-	* Makefile.am: Link the examples to glibmm explicitly.
-
-2.33.2:
-
-2011-02-11  Murray Cumming  <murrayc@murrayc.com>
-
-	Node::remove_child(): Fix a use of deleted memory
-
-	* libxml++/nodes/node.cc:
-	Use a temporary variable to avoid accessing the node C++ instance after we
-	have deleted it. Valgrind foudn this.
-	Also remove the comment about the libxml deleting our C++ instance via a
-	callback, because we don't do that anymore.
-
-2010-11-26  Murray Cumming  <murrayc@murrayc.com>
-
-	Check some libxml function return values.
-
-	* libxml++/document.cc: do_write_to_stream():
-	* libxml++/schema.cc: set_document(): Check the results from
-	xmlSchemaNewDocParserCtxt() and xmlSaveFormatFileTo().
-	Bug #635846 (Markus Elfring).
-
-2.33.1:
-
-2010-11-14  Murray Cumming  <murrayc@murrayc.com>
-
-	free_wrappers(): Fix crash.
-
-	* libxml++/nodes/node.cc: free_wrappers(): Revert my change to check
-	xmlNode::properties for all types, because the layout of some structs
-	is apparently completely different (not really deriving fully), and this
-	caused a crash in examples/sax_parser/.
-	Added an explanatory comment.
-
-2010-11-14  Murray Cumming  <murrayc@murrayc.com>
-
-	Change the --enable-examples default to yes.
-
-	* configure.ac: Build the examples by default, so we at least check the
-	build more often. Disabling them is only useful for package building,
-	which is the less common case.
-
-2010-11-14  Murray Cumming  <murrayc@murrayc.com>
-
-	Moved create_wrapper() and free_wrappers() to Node.
-
-	* libxml++/document.[h|cc]:
-	* libxml++/nodes/node.[h|cc]: Moved create_wrapper() and free_wrappers()
-	to here from Document.
-	free_wrappers(): Never return inside the switch/case, so we check
-	xmlNode::properties for all struct types, and to avoid making the behaviour
-	non-obvious.
-	* libxml++/parsers/textreader.cc:
-	* libxml++/validators/dtdvalidator.cc:
-	* libxml++/nodes/element.cc: Adapted.
-
-2010-11-08  Alessandro Pignotti  <a.pignotti@sssup.it>
-
-	Make libxml++ compatible with separate and multi-threaded libxml2 usage.
-
-	* libxml++/document.[h|cc]: Added create_wrapper() and free_wrappers(),
-	replacing on_libxml_construct() and on_libxml_destruct() .
-	Init(): Do not register these global callbacks with libxml.
-	* libxml++/nodes/element.cc:
-	* libxml++/nodes/node.[h|cc]:
-	* libxml++/parsers/textreader.cc:
-	* libxml++/validators/dtdvalidator.cc: Call these create_wrapper() before
-	ever trying to get a C++ instance from a C instance. Call free_wrappers()
-	in destructors and other places where we want the instance to be destroyed.
-
-	This avoids use of libxml's global function pointers, which are not
-	thread-safe.
-
-2010-11-08  Murray Cumming  <murrayc@murrayc.com>
-
-	Do not call xmlCleanupParser() because it is brutal.
-
-	* libxml++/document.cc: ~Init(): Do not call xmlCleanupParser() because it
-	breaks libxml generally and should only be called by an application
-	explicitly before it ends, for instance at the end of its main().
-
-2010-10-19  Knut Aksel Røysland  <knutroy@ifi.uio.no>
-
-  Node::get_parent(): Removed code duplication.
-
-  * libxml++/nodes/node.cc: get_parent() const: Use const_cast<> to call
-  the non-const version, instead of duplicating the code.
-
-2.32.0:
-
-2010-10-14  Murray Cumming  <murrayc@murrayc.com>
-
-	website: Change the mailing list location, because I moved it.

-
-	Node::find(): Check xmlNode::type for a XML_NAMESPACE_DECL.
-
-	* libxml++/nodes/node.cc: find_impl(): if the xmlNode has type
-	XML_NAMESPACE_DECL then it is actually a xmlNs, which is not like a xmlNode
-	at all (thanks to the awful undocumented libxml++ system of struct
-	inheritance).
-	So we just igore these items. We need to decide what the caller really
-	expects.
-
-2010-06-13  Murray Cumming  <murrayc@murrayc.com>
-
-	Node::find(): Revert some of my previous change because it breaks some code.
-
-	* libxml++/nodes/node.cc: find_impl(): Restore the previous behaviour,
-	because the strange use of _private only seems to happen sometimes.
-
-2010-06-13  Murray Cumming  <murrayc@murrayc.com>
-
-	Node::find(): Cope with weird use of _private in xmlNodeSet.
-
-	* libxml++/nodes/node.cc: The xmlNodeSet seems to contain extra xmlNodes that
-	were never given to on_libxml_construct(). Those xmlNodes seem to abuse
-	private_, where we find our real xmlNodes containing our C++ Nodes.
-	This fixes bug #386013 (Max Kirillov) though it depends on undocumented
-	libxml behaviour.
-
-2010-06-13  Murray Cumming  <murrayc@murrayc.com>>
-
-	Node::find(): Use libxml functions instead of direct C access.
-
-	* libxml++/nodes/node.cc: Use xmlXPathNodeSetIsEmpty(),
-	xmlXPathNodeSetGetLength() and xmlXPathNodeSetItem() instead of direct
-	xmlNodeSet struct access.
-
-2010-06-13  Murray Cumming  <murrayc@murrayc.com>

-
-    Stop exceptions when using std::cout and UTF-8.
-
-	* examples/*/main.cc: Initialize the global C and C++ locale to prevent
-    exceptions when ouputing a ustring (with non-ASCII UTF-8) to std::cout.
-    We don't see this problem when writing gtkmm apps because gtk_init() (via
-    Gtk::Main) initializes the C locale correctly.
-
-    Thanks to Daniel Elstner for the solution (he will document it properly
-    in the Glib::ustring API reference) and to Nic Reveles and others for
-    noticing the problem.
-
-2010-03-30  David King  <davidk@openismus.com>

-
-	Disable AM_MAINTAINER_MODE by default
-
-	* configure.ac: Pass the disable parameter to AM_MAINTAINER_MODE so
-	that tarball users do not need doxygen, mm-common, etc. if they modify

-	configure argument to enable documentation, and use the glibmm
-	tagfile. Check for xmllint and db2latex for DTD validation of the
-	DocBook manual and building the PDF documentation, repectively. Remove

-
-	New tarball release
-
-	* configure.in: Updated version to 2.26.1
-	* NEWS: updated
-
-2009-05-07  Murray Cumming  <murrayc@murrayc.com>
-
-	Fix the build without exceptions, hopefully.
-
-	* libxml++/parsers/textreader.cc: check_for_exceptions():
-	Add an ifdef so that this should build with exceptions disabled,
-	though there is no alternative API yet. Noticed by David King.
-
-2009-05-07  Murray Cumming  <murrayc@murrayc.com>
-

-
-2009-03-02  Armin Burgmeier  <armin@openismus.com>
-
-	* libxml++/validators/validator.h:
-	* libxml++/parsers/parser.h: Removed the vsnprintf #define on Windows.
-	This could conflict with another define otherwise. Both MSVC and MinGW
-	have vsnprintf (without underscore) as well, and I verified libxml++
-	still compiles in both. If we still need the definition for some
-	reason, then we should re-add it into the source files, so that other
-	libraries don't conflict with our definition.
-
-2009-01-09  Stef Walter  <stef-list@memberwebs.com>
-
-	* libxml++/parsers/textreader.[h|cc]: Add setup_exceptions(), setting
-	the on_libxml_error() callback, and call it from the constructors.
-	check_for_exceptions(): Actually check some member variables and throw an
-	exception if necessary.
-	This should fix bug #348006.
-	It breaks ABI because it adds member variables, but we decided that is
-	OK because nobody could actually be using this class seriously before
-	now because it had no error checking.
-
-2.24.2:
-
-2008-12-20  Armin Burgmeier  <armin@openismus.com>
-
-	* libxml++/schema.cc (set_document): Set embedded_doc_ according to
-	the embed parameter instead of always setting it to false, so that we
-	actually release the document in release_underlying().
-	(release_underlying): Free the schema in all cases, also when the
-	document was not embedded, to avoid a memory leak.
-
-	* libxml++/validators/schemavalidator.cc (parse_file, parse_memory,
-	parse_document): Make sure not to leak the xmlSchemaParserCtxtPtr in
-	case of an exception. Bug #563321, Arjan Franzen.

-	because that example does not have a DTD.
-	Show the namespace prefixes in the output.

-
-	* libxml++/parsers/parser.h:
-	* libxml++/validators/validator.h: Check for _MSC_VER instead

-
-2006-03-08  Murray Cumming  <murrayc@murrayc.com>
-
-	* libxml++/nodes/contentnode.h: get_content() documentation:
-	Replace the TODO because I know know that apos is the fifth
-	predefined entity.
-	set_content(): Mention that the predefined entities are used
-	_where necessary_ because XML does not require use of quot or
-	apos in text nodes - just in attribute values.
-
-2.13.1:
-
-2005-12-20  Murray Cumming  <murrayc@murrayc.com>

-	takes namespaces to register, using xmlXPathRegisterNs().
-	Bug #323935.
-
-2005-12-15  Murray Cumming  <murrayc@murrayc.com>
-
-	* libxml++/nodes/node.cc: set_namespace(): Pass 0 to
-	xmlSearchNs() for empty (default) namespaces, instead of
-	an empty string, as we do elsewhere. This makes
-	Document::create_root_node() for when not specifying a
-	namespace. Bug #318186 from Erik Oestby.
-
-2005-12-15  Vadim Zeitlin  <vadim@wxwindows.org >
-
-	* docs/reference/Doxyfile.in: Fix paths so buildir!=srcdir

-2005-09-21  Christophe de Vienne  <cdevienne@netcourrier.com>
-

-
-2005-05-15  Murray Cumming <murrayc@murrayc.com>
-
-	* libxml++/document.h: Add comments about possibly deriving this
-	from Node, though it needs investigation, and we can not do this
-	in the stable API.
-	* libxml++/nodes/node.cc: get_namespace(), get_namespace_prefix():
-	Return an empty string if the node is actually a Document, because
-	the underlying xmlDocument struct has no ns field. This should
-	prevent the crash in bug #161825.
-
-2005-05-15  Murray Cumming <murrayc@murrayc.com>
-
-	* docs/index.html: Add link to the LGPL text.
-
-2005-04-24  Murray Cumming <murrayc@murrayc.com>
-

- 	Bug #156352 from Jim Garrison.
-
-2005-04-24  Murray Cumming <murrayc@murrayc.com>
-
-	* libxml++/parsers/saxparser.cc: SaxParserCallback::characters()
-	Call on_characters(), not on_cdata_block(), so that the correct
-	derived handler is called. Bug #301712 and patch from
-	Aaron Walker.
-
-2005-04-24  Murray Cumming <murrayc@murrayc.com>
-
-	* libxml++-2.6.pc.in: Remove -I for the include location of
-	a config file, because we don't install one. Bug #301727
-	from Aaron Walker.
-
-2005-03-15  Murray Cumming  <murrayc@murrayc.com>
-
-	* libxml++/document.cc: set_entity_declaration(): Pass 0 instead
-	of empty strings for the public ID and system ID, if an empty
-	string is provided. This stops libxml from using a useless empty
-	string.
-
-2005-03-09  Cedric Gustin <cedric.gustin@swing.be>
-
-	* MSVC_Net2003/Makefile.am: Add blank.cpp to EXTRA_DIST.

-
-2.10.0:
-
-2005-03-08  Christophe de Vienne  <cdevienne@netcourrier.com>
-
-	* docs/reference/Makefile.am: Added one more rule so the "make
-	distcheck" works from a clean cvs working copy.
-
-2005-03-08  Christophe de Vienne  <cdevienne@netcourrier.com>
-
-	* docs/manual/Makefile.am, docs/reference/Makefile.am: Added a few
-	rules so that "make dist" generated the documentation if it's
-	absent.
-
-2005-02-15  Murray Cumming  <murrayc@murrayc.com>
-
-	* docs/manual/Makefule.am: Added insert_example_code to EXTRA_DIST,
-	though it should not be needed when building from a DIST anyway,
-	because we distribute the html.
-
-2.9.2:
-
-2005-02-13  Christophe de Vienne  <cdevienne@netcourrier.com>
-
-	* docs/manual/Makefile.am: Removed README from EXTRA_DIST.

-
-2005-02-11  Murray Cumming  <murrayc@murrayc.com>
-
-	* docs/: Added manual.
-	* configure.in: Use GLIBMM_CHECK_PERL to get the perl path, needed
-	to insert the example code in the manual.
-	* docs/Makefile.am: Move the reference and manual into a docs folder
-	so that the docs and the examples have the same relative path.
-	* docs/index.html: Mention the manual and update the links.
-
-2005-02-11  Murray Cumming  <murrayc@murrayc.com>
-
-	* libxml++/document.cc: do_write_to_string(): libml returns the
-	number of bytes instead of the number of characters, so use the
-	appropriate ustring constructor, to avoid an exception later.
-	Bug found by Cyril Picard.
-	* docs/reference/Makefile.am: Install the reference documentation.
-	Distribute the built reference documentatoin, and Do not rebuild it
-	every time.
-	* docs/reference/Doxyfile.in: Generate doxygen tags so that other
-	documentation can link to the libxml++ documentation. Use the
-	libstdc++ and glibmm doxygen tags to link to their documentation,
-	for instance for Glib::ustring.
-
-2005-01-26  Cedric Gustin <cedric.gustin@swing.be>
-
-	* MSVC_Net2003/README: Updated for 2.8.0
-
-2005-01-26  Cedric Gustin <cedric.gustin@swing.be>
-
-	* configure.in: parse micro version tags at configure time (for

-	parse_memory_raw() for libxml documents that are not utf8-encoded or
-	are encoded in an unknown encoding.
-	* examples/: Added dom_parser_raw() to test parsing of UCS2-encoded
-	text.
-
-2004-12-20  Murray Cumming  <murrayc@murrayc.com>
-
-	* This is the HEAD branch, for gnome 2.9/2.10.
-
-2004-12-18  Murray Cumming  <murrayc@murrayc.com>
-
-	* libxml++/docs/index.html: Bugs: Minor english corrections, and
-	more useful bugzilla links.
-	* libxml++/docs/Makefile.am: Build the reference documentation as
-	part of the main cvs build, but distribute it so that it does not need
-	to be rebuilt when building a tarball.
-
-2004-12-18  Murray Cumming  <murrayc@murrayc.com>
-
-	* libxml++/nodes/node.cc: Node::find(): Check the result of
-	xmlXPathEval and throw an exception about invalid xpaths, instead of
-	crashing. Bug #161549 from Caleb Epstein.
-
-2004-12-18  Murray Cumming  <murrayc@murrayc.com>
-
-	* libxml++/parsers/saxparser.cc: parse_memory(), parse_chunk(),
-	domparser.cc: parse_memory, parse_chunk(): Use Glib::ustring::bytes()
-	to get the size of the array, not size() or length(), which gets
-	the number of utf8 characters. It might not even be utf8.
-	* examples/sax_parser_build_dom/svgparser.cc: Use !empty() instead of
-	size() > 0. It is more efficient.
-
-2004-11-30  Murray Cumming  <murrayc@murrayc.com>
-
-	* libxml++/validator.h: Removed an extra ; that g++ 3.4 complains
-	about.
-
-2.8.0:
-
-2004-09-12  Murray Cumming  <murrayc@murrayc.com>

-
-2.7.0:
-
-2004-06-24  Murray Cumming  <murrayc@.com>
-
-	* configure.in, Makefile.am, libxml++-2.*.pc.in: Reverted the changes
-	that made it install a 2.8 pc.in file, and which decreased the .so
-	name. 2.8 is not parallel-installable with 2.6, and this would only
-	have been a half-done transition if it was.
-
-2004-06-22  Murray Cumming  <murrayc@murrayc.com>
-
-	* libxml++/io/outputbuffer.cc, inputbuffer.cc:
-	Added include of libxml/globals.h before include of libxml/xmlIO.h,
-	because xmlIO.h needs the definition of
-	xmlParserInputBufferCreateFilenameFunc.
-
-2004-05-28  Christophe de Vienne <cdevienne@netcourrier>
-
-	* configure.in, examples/Makefile.am, examples/dtdvalidation/Makefile.am,

-	libxml++/libxml++.h, libxml++/validators/Makefile.am,
-	libxml++/validators/dtdvalidator.[h|cc]
-	libxml++/validators/validator.[h|cc]:
-	Integrated dtdvalidator patch proposed by Guillaume Arreckx.
-	Modified a bit the patch:
-	- renamed *.cpp -> *.cc
-	- fixed a few comments which where copy/paste from other files
-	- replaced std::string with Glib::ustring
-	- Added Dtd::cobj, since the patch rely on it.
-	- added a validaty_error as suggested by jon
-
-
-2004-04-26  Christophe de VIENNE  <cdevienne@netcourrier.com>
-
-	* libxml++/nodes/contentnode.cc: Fixed set_content which used xmlNodeAddContent
-	instead of xmlNodeSetContent (thanks to Marcello Orizi who outlined it).
-
-2004-05-05  Christophe de Vienne  <cdevienne@netcourrier.com>
-
-	* libxml++/parsers/saxparser.cc: One more (last one I hope) change
-	about Glib::ustring instanciation from a buffer + lenght. We now
-	use Glib::ustring::ustring(In begin, In end) constructor. Thanks to
-	Jonathan Wakely.
-
-2004-05-04  Christophe de Vienne  <cdevienne@netcourrier.com>
-
-	* libxml++/parsers/saxparser.cc: Replaced again the use of
-	Glib::ustring(const char*) constructor by Glib::ustring(std::string).
-	Fixes #141824.
-
-2004-05-04  Christophe de Vienne  <cdevienne@netcourrier.com>
-
-	* libxml++/parsers/saxparser.cc: Replace the use of

-	Fixes #141824.
-
-2004-05-04  Murray Cumming  <murrayc@murrayc@com>
-
-	* libxml++-2.6.pc.in: Made it require glibmm-2.4, so that apps do not
-	have to check for this themselves.
-
-2.6.0:
-
-2004-04-13  Murray Cumming  <murrayc@murrayc.com>
-
-	* libxml++/Makefile.am: Change library name to 2.6 instead of 2.5.

-
-2004-03-27  Murray Cumming  <murrayc@murrayc.com>
-
-	* libxml++/parsers/textreader.[h|cc]: Correct constness of

-
-2.5.2:
-
-2004-02-16  Christophe de VIENNE  <cdevienne@netcourrier.com>
-
-	* libxml++/nodes/element.cc: Check return value of xmlHasNsProp to
-	fix issue #134390 (as reported by John Coyle). Use xmlHasProp instead
-	of testing each attributes.
-
-2004-02-16  Christophe de VIENNE  <cdevienne@netcourrier.com>
-
-	* libxml++-2.6.pc.in: Added libxml-2.0 to Requires: and removed

-	http://sourceforge.net/tracker/index.php?func=detail&aid=842730&group_id=12999&atid=312999
-	with Glib::ustring instead of std::string, and member functions names
-	changed to be consistent with other interfaces.

-	of TextReader interface.
-
-2004-02-05  Jim Garrison  <garrison@case.edu>

-
-2004-01-13  Christophe de Vienne  <cdevienne@alphacent.com>
-
-	* libxml++/io/document.cc: Gives NULL strings instead of empty ones to

-
-2004-01-12  Christophe de Vienne  <cdevienne@alphacent.com>
-
-	* libxml++/io/outputbuffer.cc: Fix return value of xmlIO callbacks. (Fixes

-
-2003-12-19  Murray Cumming  <murrayc@usa.net>
-
-	* configure.in: Added glibmm-2.4 to the pkg-config check.
-	* Used regexxer to do a complete std::string/Glib::ustring rename.
-	Everything seems to still work. I think the parse_chunk(stream)
-	stuff might need some attention/thought.
-
-2003-12-19  Murray Cumming  <murrayc@usa.net>
-
-	* removed acinclude.m4 because we do not need it anymore because
-	we do not need AM_LIBXML now that we use pkg-config.
-	* libxml++/Makefile.am: Generate a library with 2.5 in the name,
-	instead of 1.0
-	* configure.in: Change version to 2.5.0.
-	* examples/Makefile.am_fragment: Link to the new library name.
-	* Renamed libxml++-1.0.pc.in to libxml++-2.6.pc.in: and changed the
-	library name that pkg-config reports for --libs.
-	* So, this is now the libxml++ 2.6 API, with a library name of 2.5
-	while it is unstable. It is parallel-installable with libxml++ 1.0.
-
-This is the HEAD branch, for libxml++ 2.5/2.6.

-
-2003-12-08  Murray Cumming  <murrayc@usa.net>
-
-	* examples/ Added sax_parser_build_dom example from Dan Dennedy.
-	It does some funky stuff (see the comments) but it is an
-	interesting concept. See the description in examples/README.
-
-2003-12-03  Christophe de Vienne  <cdevienne@netcourrier.com>
-
-	* configure.in: use libxml-2.0 instead of xml2 for libxml2 detection
-	by pkg-config.
-	* libxml++/parser/sax_parser.[h|cc]: Replaced AttributeMap by AttributeList,
-	which is now an ordered container (std::deque). Added a functor that can be
-	used with std::find_if to get an Attribute by it's name.
-	* libxml++/document.h: Fixed a typo in a doxygen command.
-
-2003-12-03  Murray Cumming  <murrayc@usa.net>
-
-	* examples/README: explained what the examples do.
-
-2003-11-28  Christophe de Vienne  <cdevienne@alphacent.com>
-
-	* libxml++/docs/index.html: Added libxml2 version we relay on, as
-	suggested by Paul Breslin.
-	* configure.in: Prepared 0.28 release. Check for libxml2 >= 2.5.8 using
-	pkg-config instead of old-style autoconf macro.
-	* acinclude.m4: Removed.
-
-2003-11-27  Murray Cumming  <murrayc@usa.net>
-
-	* Added examples/sax_parser_entites to test the new functionality.
-	* Added doxygen documentation to almost every class and method,
-	including mentioning that the parse methods throw exceptions.
-
-2003-11-27  Murray Cumming  <murrayc@usa.net>
-
-	* Applied patch from Dan Dennedy to add entity handling to the
-	SAX parser, using a 2nd Document instance to manage the entity
-	definitions in order to provide a default entity reference resolver
-	implementation for on_get_entity(). With some minor changes from me.
-
-2003-11-13  Christophe de Vienne  <cdevienne@netcourrier.com>
-
-	* libxml++/io/Makefile.am: Made libio a non installed library.
-	* libxml++/document.cc: Fixed a serious issue with threading: callbacks
-	were defined only for the main thread.
-
-0.27:
-
-2003-10-28  Murray Cumming  <murrayc@usa.net>
-
-	* libxml++/nodes/element.[h|cc]: Changed get_child_content() to
-	get_child_text(), set_child_content() to set_child_text(),
-	add_comment() to add_child_comment(), and add_content() to
-	add_child_content() to make the API clearer.
-
-2003-10-25  Christophe de Vienne  <cdevienne@netcourrier.com>
-
-	* libxml++/document.[h|cc]: Added Document::add_comment and added some
-	documentation.
-
-2003-10-22  Murray Cumming  <murrayc@usa.net>
-
-	* libxml++/parsers/saxparser.[h.cc]: Added on_entity_declararation()
-	callback, and demonstrated it in examples/sax_parser/.
-	Added documentation to on_get_entity() giving clues about how to use
-	it, though it is too difficult for me to try.
-
-2003-10-18  Christophe de Vienne  <cdevienne@netcourrier.com>
-
-	* All: All private members previously having a leading underscore in their
-	name now have it postfixed. Ex: _impl becomes impl_.
-
-2003-10-18  Christophe de Vienne  <cdevienne@netcourrier.com>
-
-	* libxml++/io/outputbuffer.[h|cc]: Removed conversion operator to
-	underlying C structure. cobj() is now public.
-	* libxml++/document.cc: use OutputBuffer::cobj() instead of implicit
-	conversion.
-
-2003-10-18  Christophe de Vienne  <cdevienne@netcourrier.com>
-
-	* libxml++/nodes/Makefile.am: Removed some trailing white spaces after a
-	backslash.
-
-2003-10-14  Murray Cumming  <murrayc@usa.net>
-
-	* Added lots of doxygen documentation, try to document everything 100%.
-	* libxml++/nodes/element.[h|cc]: Made get_attributes() non-const
-	and added a const get_attributes() const overload, like
-	Node::get_children().
-	* Moved AttributesList typedef from Node to Element, because that's
-	where it is used.
-	* libxml++/parsers/parser.[h|cc]: Added get/set_substitute_entities(),
-	like get/set_validate(), which affects _context->replaceEntities in
-	initialize_context().
-	* Added libxml++/nodes/entityreference.[h|cc], with a
-	get_resolved_text() method.
-	* libxml++/document.cc:
- - on_libxml_construct(): For the default, used when a node is not
-	recognised, create a Node rather than a ContentNode. Everything is a
-	Node so this should have less chance of being wrong.
-	- Added case to create an EntityReference.
-	* Added examples/dom_parse_entities.
-
-2003-09-30  Jonathan Wakely  <redi@kayari.org>
-
-	* libxml++/document.cc, libxml++/nodes/element.cc,
-	libxml++/nodes/node.cc: Preserve const-quals when casting between
-	strings of different character types.
-
-2003-09-26  Christophe de Vienne  <cdevienne@netcourrier.com>
-
-	* libxml++/io/outputbuffer.[h|cc]: Yet another cleaning of the interface
-	and implementation. OutputBuffer is now non copyable, and the callback
-	process is now the same for write and close.
-	* libxml++/io/(ostream)outputbuffer.h: Added Doxygen documentation.
-
-2003-09-26  Christophe de Vienne  <cdevienne@netcourrier.com>
-
-	* libxml++/io/: Small corrections after Murray comments on the patch. It's
-	even more clean now.
-
-2003-09-26  Christophe de Vienne  <cdevienne@netcourrier.com>
-
-	* libxml++/io/: Added classes to wrap xmlIO output buffers. This classes
-	are OutputBuffer and OStreamOutputBuffer.
-	* libxml++/document.h:
-	- Added write_to_stream, which is implemented thanks to OutputBuffer.
-	- Removed virtual specifier on write_to_xxx functions. Their
-	implemention now calls a private virtual function do_write_to_xxx. This
-	also avoid having almost identical functions implementation in normal and
-	formatted versions of the functions.
-
-2003-09-24  Christophe de Vienne  <cdevienne@netcourrier.com>
-
-	* libxml++/examples/dom_build/main.cc: Now demonstrate add_comment
-	too.
-
-2003-09-24  Dan Dennedy
-
-	* libxml++/nodes/element.[h|cc]: Added Element::add_comment.
-
-2003-09-23  Christophe de Vienne  <cdevienne@netcourrier.com>
-
-	* libxml++/document.h, libxml++/keepblanks.h, libxml++/noncopyable.h,
-	libxml++/nodes/node.h: Updated documentation.
-
-0.26:
-
-2003-09-22  Christophe de Vienne  <cdevienne@netcourrier.com>
-
-	* examples/dom_build/main.cpp: Use Element::set_attribute instead of
-	Element::add_attribute which no longer exists.
-
-2003-09-19  Murray Cumming  <murrayc@usa.net>
-
-	* libxml++/node/element.h: Removed add_attribute because it is the same as
-	set_attribute.
-
-2003-09-18  Murray Cumming  <murrayc@usa.net>
-
-	* libxml++/node/element.h: Added set_namespace_declaration().
-	  element, node: methods take prefix instead of uri and prefix, because
-	that's what we want to specify most of the time. If no such namespace
-	prefix has been declared then an exception will be thrown. If we want
-	to specify a node name and attribute namespaces by uri (which would
-	result in a prefix in the eventual .xml code) then we could add those
-	methods later. If anybody needs them.
-
-2003-09-17  Christophe de Vienne  <cdevienne@netcourrier.com>
-
-	* docs/reference/Doxyfile(.in): Doxyfile is now generated from Doxyfile.in
-	by configure so the version number is included in main page. The dot image
-	format is changed to png, the index is not disabled anymore.
-
-2003-09-15  Fredrik Arnerup
-
-	* libxml++/document.cc: Added a call to xmlInitParser to avoid
-	threading problems.
-
-2003-09-05  Murray Cumming  <murrayc@usa.net>
-
-	Based on the patch from Dan Dennedy, with changes:
-	* libxml++/node.[h|cc],
-	libxml++/element.[h|cc]: Added namespace_uri and namespace_prefix
-	parameters to methods, to support speficiation of nodes and children
-	also with namespace information.
-	* Added Node::get_namespace_prefix() and get_namespace_uri() and
-	set_namespace().
-	* examples/dom_build/: Modified the example to do namespace stuff,
-	to test this.
-
-2003-08-20  Murray Cumming  <murrayc@usa.net>
-
-	* libxml++/node.[h|cc]: import_node() now takes a _const_ Node, as
-	suggested by Rafael Vuijk.
-
-2003-07-20  Ephraim Vider <eff@eplication.com>
-
-	* win32_msvc6: libxml++.dsp, examples/import_node.dsp, examples/Makefile.am:
-		- added import_node example project
-
-0.25:
-
-2003-07-16  Christophe de Vienne  <cdevienne@netcourrier.com>
-
-	* libxml++.m4, xml++-config.in, configure.in, Makefile.am: removed old-style
-	autoconf libxml++ detection macro and script.
-
-2003-07-15  Christophe de Vienne  <cdevienne@netcourrier.com>
-
-	* all but exceptions/*.[h|cc]: removed throw specification from functions
-	declaration.
-
-2003-07-11  Eric Bourque <ericb@computer.org>
-
-	* nodes/node.[h|cc]: Added import_node function
-	* examples/import_node: Added an example of using import_node, and modified
-	autoconf files accordingly.
-
-2003-06-25  Ephraim Vider <eff@eplication.com>
-
-	* win32_msvc6: libxml++.dsp: added _REENTRANT to support libxml with threads
-	- examples/Makefile.am: added new example project
-
-2003-06-16  Christophe de Vienne  <cdevienne@netcourrier.com>
-
-	* docs/index.html: Added a link to Doxygen website.
-
-2003-06-16  Ephraim Vider <eff@eplication.com>
-
-	* win32_msvc6/*: Fixed MSVC6 project files.
-
-2003-06-13  Christophe de Vienne  <cdevienne@netcourrier.com>
-
-	* docs/Makefile.am: Fixed the post-html rule which was sending twice the
-	reference.
-	* docs/index.html: Added keyword "XML".
-
-0.24:
-
-2003-06-11  Christophe de Vienne  <cdevienne@netcourrier.com>
-
-	* libxml++/parsers/domparser.cc:
-		- Fixed parse_stream. Parsing success was not checked before creating
-		Document.
-		- Check for errNo after parsing.
-
-2003-06-02  Ephraim Vider
-	* libxml++/nodes:
-	Added ContentNode as a base class for all non-element nodes
-	- TextNode and CommentNode are derived from ContentNode
-	- Added CdataNode and ProcessingInstructionNode as specific types
-	derived from ContentNode
-	- Will create ContentNode as a default node type when assert is
-	disabled
-	- Modified dom_parser example to better handle new types
-	Modified files: textnode.[h|cc] commentnode.[h|cc]
-	Added files: contentnode.[h|cc] cdatanode.[h|cc] processinginstructionnode.[h|cc]
-
-	* node.cc: - Fix. return empty string and not 0
-	* updated MSVC projects to include new sources and example
-
-2003-06-10  Jonathan Wakely  <redi@kayari.org>
-
-	* libxml++/parsers/saxparser.cc: Replace <istream> with <iostream>
-	to support older compilers.
-
-2003-06-06  Christophe de Vienne  <cdevienne@alphacent.com>
-
-	* libxml++/document.cc: Little change in write_to_xxx_formatted. The
-	keepblanks parameter is kept to true, but xmlIndentOutputTree is set to 1.
-	This avoid libxml2 to add some significant whitespace into content nodes,
-	but still format the output.
-
-2003-06-05  Christophe de Vienne  <cdevienne@alphacent.com>
-
-	* libxml++/keepblanks.[h|cc]: Moved KeepBlanks::Default definition
-	to .cc file if compiler is MSVC 6.0.
-
-2003-06-04  Morten Hanssen  <morten.hanssen@pd.politiet.no>
-
-	* libxml++/Document.cc: Fixed a memory leak in
-	write_to_string[_formatted]() functions.
-
-2003-06-02  Murray Cumming  <murrayc@usa.net>
-
-	* libxml++/Document.[h|cc]: Removed the standalone parse_* methods
-	because they just duplicate functionality and nobody seems to be
-	using them.
-	Renamed the private construct() and destruct() callbacks to
-	on_libxml_construct() and on_libxml_destruct() and added some
-	simple comments to explain their purpose.
-	* libxml++/node.[h|cc]: Added Node::is_white_space(), to make it
-	easier for the application to ignore white space. Used it in
-	the dom_parser example..
-
-2003-05-29  Murray Cumming  <murrayc@usa.net>
-
-	* Removed some struct keywords from method and variable definitions.
-	They don't seem to be necessary, and they do not match the method
-	definitions in the .cc files.
-	* Some syntax clean-up - tabs to spaces and adding spaces.
-	* examples/dom_parse/main.cc: Say when something is a text node.
-
-2003-05-28  Christophe de Vienne  <cdevienne@netcourrier.com>
-
-	* lixml++/document.[h|cc]: Added write_to_file_formatted and
-	write_to_string_formatted.
-
-2003-05-25  Jonathan Wakely  <redi@kayari.org>
-
-	* libxml++/parsers/saxparser.cc: Included <cassert>
-
-2003-05-23  Jonathan Wakely  <redi@kayari.org>
-
-	* libxml++/parsers/saxparser.[h|cc]: Correct comments.
-
-2003-05-23  Christophe de Vienne  <cdevienne@netcourrier.com>
-
-	* all header files: Removed libxml2 headers inclusion. Added necessary
-	forward declaration of libxml2 structures.
-	* libxml++/parsers/saxparser.[h|cc]: Moved static callback functions into
-	a struct defined only in the .cc file, SaxParserCallback.
-	Added boolean parameter to SaxParser constructor to activate on_get_entity
-	callback (default to false). This technique could eventually be extended to
-	other functions in the future.
-	* libxml++-1.0.pc.in: removed libxml headers include path from Cflags.
-
-2003-05-22  Christophe de Vienne  <cdevienne@netcourrier.com>
-
-	* libxml++/nodes/node.[h|cc]: Added Node::set_name().
-
-2003-05-20  Christophe de Vienne  <cdevienne@netcourrier.com>
-
-	* libxml++/nodes/[node.cc|element.h]: Minor syntax adjustments to allow
-	compiling with g++ -ansi -pedantic -Wall without any warning.
-
-0.23:
-
-2003-05-20  Christophe de Vienne  <cdevienne@netcourrier.com>
-
-	* libxml++/keepblanks.[h|cc]: New KeepBlanks class which change settings
-	related to xmlKeepBlanksDefault and xmlIndentTreeOuput.
-	* libxml++/[document.cc|parsers/*parsers.cc]: use KeepBlanks instead of
-	manually call xmlKeepBlanksDefault(). Significant white spaces are not
-	removed/added anymore.
-	* example/dom_read_write/example_output.xml: removed.
-
-2003-05-16  Murray Cumming  <murrayc@usa.net>
-
-	* libxml++/noncopyable.[h|cc]: New xmlpp::NonCopyable base class, which
-	should prevent people from using automatically-generated copy
-	constructors when they shouldn't. Not tested yet.
-	* libxml++/examples/dom_read_write: New example/test. This does
-	show that we are removing significant white space. This has been
-	discussed on the list and apparently Christophe has a fix for it.
-
-2003-05-06  Andy Glew <andy.glew@amd.com>
-
-	* libxml++/nodes/node.cc: Node::find( nonexistent_xpath ) now return
-	empty NodeSet
-
-2003-04-24  Christophe de Vienne  <cdevienne@netcourrier.com>
-
-	* libxml++/parsers/saxparser.cc: Fixed a memory leak pointed by "thierry"
-	<thierry.blanchard@digitech.fr>. The sax handler of the context is not reset
-	to 0 before context release anymore. In parse() the default one is saved
-	then restored after effective parsing, so libxml handle itself its
-	destruction.
-
-2003-04-20  Christophe de Vienne  <cdevienne@netcourrier.com>
-
-	* libxml++/document.cc: Removed a warning message that was put on std::cout
-	if an unknown type of node was created and replaced it by an assert. This
-	avoid the need to include iostream(.h).
-
-2003-04-18  Murray Cumming  <murrayc@usa.net>
-
-	* Applied Jaka Jejcic's patch to fix compilation on NetBSD, including
-	iostream.h instead of istream.h.
-
-2003-04-09  Eric Bourque <ericb@computer.org>
-
-	* libxml++.spec.in: modified spec file to be library version agnostic.
-
-2003-03-19  Ephraim Vider
-
-	* added msvc support in win32_msvc6.
-
-2003-03-17  Ephraim Vider
-
-	* Modified sax_exception example:
-	- corrected Clone() return type for MyException in myparser.[h|cc]
-	- catch all exceptions in main.cc - handle real errors too
-
-0.22:
-
-2003-03-15  Murray Cumming  <murrayc@usa.net>
-
-	* libxml++/parser/domparser.cc: Added const overload of get_document().
-
-2003-03-13  Christophe de Vienne
-
-	* libxml++/parser/domparser.cc: Test if context creation is
-	successfull in the different parse_xxx functions. If it is no an
-	internal_error is thrown.
-
-2003-03-06  Ephraim Vider
-
-	* made DomParser a wrapper around Document
-	removed all functions that were duplicates of document
-	functions and added get_document()
-	files: domparser.[h|cc] document.h
-
-	* fixed compilation errors for msvc:
-	- corrected Clone() return type for derived exceptions
-	- corrected getline to std::getline in saxparser.cc
-	- changed clear() to erase() in parser.cc
-	- added #define for vsprintf in parser.h
-	- fixed warning in element.cc
-
-0.21:
-
-2003-02-21  Eric Bourque
-
-	* Added spec.in, for creating RPMs.
-
-2003-02-20  Murray Cumming  <murrayc@usa.net>
-
-	* libxml++/nodes/node.[h|cc]: Moved get_child_content(),
-	set_child_content(), add_content(), and has_content() from Node to
-	derived Element class instead of just throwing an exception if it
-	isn't an Element. This means you can't use set_child_content() on a
-	TextNode - you should be using TextNode::set_content() anyway, which
-	makes a lot more sense. Corrected set_child_content() to create a
-	TextNode instead of creating a node with the content as the name,
-	fixing the output of the dom_build example.
-
-2003-02-20  Murray Cumming  <murrayc@usa.net>
-
-	* libxml++/parsers/parser.[h|cc]:
-	initialize_contex(): Request iniitialization and connect callbacks
-	check_exception(): Throw exception if any validation problems have
-	been found - the messages are built up gradually by repeated
-	callbacks.
-	set_validate(): Enables validation before calling parse_*().
-	Alternatively, use 2nd bool parameter to the DomParser constructor.
-	* libxml++/exceptions/: Added validation_error class.
-	* examples/dom_parser: Added a DTD and changed example.xml to
-	something that uses it. Also added example_invalid.xml to test
-	the exceptions.
-
-2003-02-12  Ole Laursen  <olau@hardworking.dk>
-
-	* examples/sax_parser/main.cc: Added chunk-wise parsing to the
-	example.
-
-	* libxml++/parsers/saxparser.[h,cc]: Added functionality for
-	parsing chunks of data.
-
-2003-02-17  Murray Cumming  <murrayc@usa.net>
-
-	* libxml++/parsers/*.[h|cc]: All parsing is now done via contexts,
-	which required a little duplication of the implementation of functions
-	such as xmlParseFile(), most of which is now in
-	DomParser::parse_context(). This avoids use of global functions such
-	as xmlKeepBlanksDefault() by setting these booleans directly in the
-	context, in Parser::initialize_context().
-	However, xmlCreateFileParserCtxt() does seem to be affected by
-	xmlKeepBlanksDefault so we still have to use it temporarily, restoring
-	the old value afterwards - see the comments in DomParser::parse_file().
-	This should allow us to add validation to the API.
-
-0.20:
-
-2003-02-15  Murray Cumming  <murrayc@usa.net>
-
-	* libxml++/nodes/node.cc: (remove_child): Implemented it with
-	xmlUnlinkNode and xmlFreeNode, so that it's actually removed.
-
-2003-02-15  Murray Cumming  <murrayc@usa.net>
-
-	* Added examples/dom_xpath, with code from Stefan Seefeld's dom
-	example.
-
-2003-02-15  Murray Cumming  <murrayc@usa.net>
-
-	* Reverted the Node::child_iterator API change because it was
-	undiscussed and is unfinished. The BRANCH_1_0 and HEAD branches are now
-	merged. BRANCH_1_0 should no longer be used. This was never in 0.19.
-
-0.19:
-
-2003-02-07  Murray Cumming  <murrayc@usa.net>
-
- 	* Moved method implementations such as get_attributes() into derived
- 	classes instead of using "using methodname();". That seems clearer.
- 	However it shows that we should probably create a shared base class for
- 	Content and Comment, as in the DOM.
-
-2003-02-06  Murray Cumming  <murrayc@usa.net>
-
-	* libxml++/parsers/saxparser.[h|cc]: Corrected some coding style.
-
-2003-02-06  Murray Cumming  <murrayc@usa.net>
-
-	* Changed c_obj() to cobj() because it's more like gobj() used in
-	gtkmm, gnomemm, etc.
-
-2003-02-06  Murray Cumming  <murrayc@usa.net>
-
-	* libxml++/nodes/node.*: Corrected code style.
-
-2003-02-06  Murray Cumming  <murrayc@usa.net>
-
- 	* libxml++/nodes/node.[h|cc], libxml++/attribute.[h|cc]: Made c_obj()
- 	accessors public so people can use them. Provided const and non-const
- 	versions of them. Put implementation in .cc file.
- 	* Reverted some of Stefan's coding style changes and corrected the
- 	coding style in libxml++/nodes/document.[h|cc].
- 	* libxml++/document.h: Made the destructor virtual, because there are
- 	virtual methods.
-
-2002-02-04  Stefan Seefeld <seefeld@sympatico.ca>
-
-	* libxml++/node.[h,cc]: add new insert_child and append_child methods
-	(using new iterators), add get_path and find methods for xpath lookup
-
-	* examples/dom: new example code to illustrate the new features
-
-2002-02-03  Stefan Seefeld <seefeld@sympatico.ca>
-
-	* libxml++/node.h, libxml++/parsers/saxparser.[h,cc],
-	examples/sax_parser/*.[h,cc], examples/sax_exception/*.[h,cc]:
-	SaxParser::AttributeMap is now a map<string, string>.
-
-2002-02-03  Stefan Seefeld <seefeld@sympatico.ca>
-
-	* libxml++/node.h: add child_iterators for simple C++ style
-	iteration (to get eventually rid of NodeList)
-
-2002-02-03  Stefan Seefeld <seefeld@sympatico.ca>
-
-	* libxml++/attribute.[h,cc], libxml++/nodes/node.[h,cc],
-	libxml++/document.cc: derive Attribute from Node, and make
-	get_value() use libxml2 accessor instead of raw pointer
-
-2002-02-03  Stefan Seefeld <seefeld@sympatico.ca>
-
-	* libxml++/document.[h,cc], libxml++/parsers/domparser.[h,cc],
-	libxml++/libxml++.h, libxml++/Makefile.am: introduce new Document type.
-	* examples/dom_build/main.cc: make dom_build example use new
-	Document type
-
-2002-02-03  Stefan Seefeld <seefeld@sympatico.ca>
-
-	* acinclude.m4: The AM_LIBXML macro now checks for a libxml2
-	version >= 2.5.1.
-	* libxml++/nodes/node.cc: compare strings, not pointers, in
-	get_attribute()
-
-2003-01-31  Stefan Seefeld  <seefeld@sympatico.ca>
-
-	* various: overall change to use libxml2 as implementation,
-	  not only as I/O backend. With corrections by Murray Cumming.
-    Further explanation by murrayc: Instead of maintaining its own
-    C++ data structures and then creating libxml data structures from them,
-    it now manipulates the libxml data structures directly, so the C++ and C

-2003-01-21  Valentin Rusu <sourceforge@valentinrusu.net>
-
- 	* added CDATA section handler to SaxParser
-
-2003-01-05  Valentin Rusu <sourceforge@valentinrusu.net>
-
- 	* fixed a potential buffer overflow problem into saxparser.cc
-
-0.18:
-
-2003-01-31  Stefan Seefeld  <seefeld@sympatico.ca>
-
-	* various: overall change to use libxml2 as implementation,
-	  not only as I/O backend.
-
-2003-01-05  Murray Cumming  <murrayc@usa.net>
-
-	* examples/dom_build/main.cc: Removed some useless test C code.
-
-2002-12-24  Morten Brix Pedersen  <morten@wtf.dk>
-
-        * Include <iostream> instead of <istream> to compile on gcc 2.95.4.
-
-2002-12-26  Murray Cumming  <murrayc@usa.net>
-
-	* libxml++/nodes/element.c (write): Add back the code to write the
-	attributes to the C libxml structure. This code got lost during the
-	refactoring.
-
-2002-12-25  Murray Cumming  <murrayc@usa.net>
-
-	* Removed unused constructors, to simplify things. Made Node's
-	destructor virtual, because we delete them polymorphically, and
-	because it has virtual methods.
-
-2002-12-25  Murray Cumming  <murrayc@usa.net>
-
-	* libxml++/nodes/node.[h|cc]: Removed the initialized member
-	variable and its accessor, because it's not used.
-
-2002-12-19  Murray Cumming  <murrayc@usa.net>
-
-	* libxml++/parsers/domparser.[h|cc]: get/set_root_node() now returns
-	an Element instead of a Node.
-
-2002-12-19  Murray Cumming  <murrayc@usa.net>
-
-	* Changed const & accessors to get_*() methods. For instance,
-	Node::name -> Node::get_name
-	Node::children() -> Node::get_children()
-	Element::attributes() -> Element::get_attributes()
-	Attribute::value -> Attribute::get_value()
-
-2002-12-18  Murray Cumming <murrayc@usa.net>
-
-	* Added libxml++/nodes/commentnode.[h|cc] and used it in Node so that
-	comments don't just show up as name=comment Nodes.
-	* examples/dom_parser/example.xml: Added a comment.
-	* examples/dom_parser/main.cc: Do a dynamic_cast<> check for comments
-	too.
-
-2002-12-18  Christophe de Vienne  <cdevienne@alphacent.com>
-
-	* libxml++/parser/saxparser.cc: Fixed a bug in exception handling in
-	parse_stream. Thanks to Fredrik Arnerup <e97_far@e.kth.se> for reporting
-	the bug.
-
-2002-12-17  Murray Cumming  <murrayc@usa.net>
-
-	* Added libxml++/nodes/textnode.[h|cc]. This should remove the
-	confusion about whether content()/set_content() should be used on
-	a text node or the parent of a text node.
-	* libxml++/nodes/node.[h|cc]:
-	- Node::write() is now virtual, and
-	different in TextNode.
-	- content() replaced by get_child_content, which returns a TextNode*
-	instead of a string.
-	- set_content() replaced by set_child_content().
-	* Added libxml++/nodes/element.[h|cc] so that TextNode can inherit
-	from a Node class without the attributes API. As per the Java DOM API,
-	Node still has the children API - I guess there's some reason for that,
-	though I don't see how a TextNode could have children.
-
-2002-12-17  Murray Cumming  <murrayc@usa.net>
-
-	* Moved node.[h|cc] into nodes sub directory, in preparation for the
-	multiple-node-types API change.
-
-2002-12-12  Jonathan Wakely <redi@kayari.org>
-
-	* libxml++/parsers/saxparser.cc, saxparser.h (on_get_entity): New
-	virtual function to allow derived classes to override entity handling
-
-2002-12-16  Murray Cumming  <murrayc@usa.net>
-
-	* libxml++/node.cc: write():
-	- Don't set the node->type directly. Let
-	xmlNodeSetContent take care of adding a suitable child node. This
-	was leading to segfaults when write() later tried to add a child node
-	to a text node.
-	- Throw internal_error exception when xmlNewChild returns NULL.
-
-
-0.17:.
-
-2002-12-10  Christophe de Vienne <cdevienne@alphacent>
-
-	* configure.in: updated version numbers for next release. Generic
-	version is now 0.17, library version is 3:0:0
-	* NEWS: updated with changes since 0.16 version.
-
-2002-12-10  Christophe de Vienne <cdevienne@alphacent.com>
-
-	* libxml++/node.cc: fixed write() which was using the accessors content()
-	and has_content(). Since they return something for both the text
-	node and the parent node, the output was weird.
-
-2002-12-09  Murray Cumming  <murrayc@usa.net>
-
-	* libxml++/node.cc: content(): If the cached content string is empty,
-	try to get the content of a child "text" node. This makes content()
-	work as expected after creating a document with set_content() and
-	later reparsing it.
-
-2002-12-09  Murray Cumming  <murrayc@usa.net>
-
-	* libxml++/parsers/dom_parser.cc (release_underlying): Set pointers
-	to 0 so that the get_*() methods generate new instances instead of
-	returning invalid pointers.
-
-2002-12-09  Murray Cumming  <murrayc@usa.net>
-
-	* libxml++/node.cc: Node::remove_child() and Node::remove_attribute:
-	delete the objects when forgetting about them.
-	* libxml++/node.h: Added reference docs explaining the above.
-
-2002-12-07  Murray Cumming  <murrayc@usa.net>
-
-	* libxml++/parsers/domparser.cc, saxparser.cc: Added comments about
-	the use of xmlKeepBlanksDefault() and xmlLineNumbersDefault().
-	* libxml++/parsers/saxparser.[h|cc]: Change exception & to exception&.
-
-2002-12-06  Christophe de Vienne <cdevienne@alphacent.com>
-
-	* libxml++/parsers/domparser.cc: Enabled xml option LineNumbers
-	and disabled KeepBlanks before each parsing.
-	* libxml++/parsers/sax_parser.cc: Enabled xml option KeepBlanks
-	before each parsing.
-	* example/dom_parser/main.cc: Added line number display for each
-	non-content node. Changed a bit content display
-	* Note: in a near future I may change these options settings to
-	let the user choose which options he wants/wants not.
-
-
-2002-12-03  Jone Marius Vignes <jmvignes@broadpark.no>
-
-	* libxml++/parsers/domparser.cc: Changed the exception in
-	write_to_string() to "write_to_string() failed."
-	* libxml++/parsers/domparser.h: Corrected documentation of
-	write_to_string() and write_to_file() to clarify that these methods
-	doesn't return booleans
-
-2002-12-02  Christophe de Vienne <cdevienne@alphacent.com>
-
-	* libxml++/exceptions/*.[h|cc]: Added and implemented virtual
-	methods Raise() and	Clone.
-	* libxml++/parser/sax_parser.[h|cc]: Each callback method can now
-	throw some exceptions as long as they herit from xmlpp::exception
-	AND implement Raise() and Clone().
-	* libxml++/examples/sax_exception/: Added an example which demonstrate
-	the use of exceptions inside a SaxParser.
-
-2002-11-29  Murray Cumming  <murrayc@usa.net>
-
-	* autogen.sh: Added libtoolize to generate files such as ltmain.sh.
-
-2002-11-28  Christophe de Vienne <cdevienne@alphacent.com>
-
-	* acinclude.m4: The AM_LIBXML macro now checks for a libxml2
-	version >= 2.4.1.
-
-2002-11-21  Christophe de Vienne <cdevienne@alphacent.com>
-
-	* libxml++/parsers/*.[h|cc]: added Parser::parse_stream method
-	and implemented it in both DomParser and SaxParser. Tests based
-	on the examples (not commited in the cvs) worked perfectly.
-
-2002-11-20  Christophe de Vienne <cdevienne@alphacent.com>
-
-	* libxml++/parsers/saxparser.cc: fixed a memory leak (thanks
-	to Chris Leishman <masklin@debian.org> who reported it.
-
-2002-11-20  Murray Cumming  <murrayc@usa.net>
-
-	* Changed use of the term properties to attributes in the API,
-	because that is the correct terminology.
-
-0.16:
-
-2002-11-19  Christophe de Vienne <cdevienne@alphacent.com>
-
-	* configure.in: updated version numbers for next release.
-	version is set to 0.16, library version to 2:0:0
-
-2002-11-19  Murray Cumming  <murrayc@usa.net>
-
-	* docs: Added index.html, which can be a main website page.
-	* docs/Makefile.am: Added rsync command to upload the html,
-	including the reference documentation.
-
-2002-11-19  Murray Cumming  <murrayc@usa.net>
-
-	* Added Dtd class, which is just a collection of std::strings.
-	* libxml++/parsers/domparser.[h|cc]: Added set_internal_subset() and
-	get_internal_subset() to set the DTD declaration. This is set in the
-	underlying C xmlDoc during write_to_file() and write_to_disk().
-
-2002-11-18  Murray Cumming  <murrayc@usa.net>
-
-	* libxml++/node.[h|cc]:
-	- Rename is_content() to has_content(), because that's what it tells
-	us. Removed _is_content member bool - we can check _content.empty()
-	instead.
-	- write(): Do not manually set the xmlNode's type field to TEXT. This
-	corrupted the tree. Tested content nodes in example/dom_build.
-
-2002-11-18  Murray Cumming <murrayc@usa.net>
-
-	* libxml++/parsers/domparser.cc (write_to_*): Corrected no-root-node
-	check.
-
-2002-11-18  Murray Cumming  <murrayc@usa.net>
-
-	* libxml++/exceptions/exception.[h|cc]: Corrected signature of what()
-	method, adding const throw().
-
-2002-11-18  Murray Cumming  <murrayc@usa.net>
-
-	* libxml++/parsers/domparser.[h|cc]: Added DomParser::set_root_node().
-	* examples: Added dom_build, to show runtime construction of an XML
-	tree.
-
-2002-11-18  Murray Cumming  <murrayc@usa.net>
-
-	* Parser, DomParser, SaxParser: parse_file() and parse_memory() now
-	throw exceptions.
-	* DomParser::write_to_file(): throws exception instead of using a bool
-	return value.
-	* examples/domparser/: Catches exceptions.
-
-2002-11-18  Christophe de Vienne <cdevienne@alphacent.com>
-	* libxml++/exceptions: splitted exception.[h|cc] in this directory.
-	The libxml_error has been removed for now, and a parse_error added.
-
-2002-11-17  Christophe de Vienne <cdevienne@alphacent.com>
-	* libxml++/attribute.h: Changed macro __LIBXMLPP_PROPERTY_H to __LIBXMLPP_ATTRIBUTE_H
-	* libxml++/exception.[h|cc]: Added xmlpp::exception, xmlpp::libxml_error and
-   	xmlpp::internal_error classes. It's very basic for now.
-
-2002-11-17  Murray Cumming  <murrayc@usa.net>
-
-	* Node, Attribute: set_*() method now have void return types.
-	* DomParser: Now has an empty underlying in-memory document when the
-	default constructor is used. This means that get_root_node() should
-	always return something, so we can build XML documents in memory
-	without loading any XML first.
-
-2002-11-16  Murray Cumming  <murrayc@usa.net>
-
-	* libxml++/attribute.h: Added explicit to constructor.
-
-2002-11-16  Murray CUmming  <murrayc@usa.net>
-
-	* libxml++/parsers/domparser: Renamed write() method to write_to_file()
-	and added write_to_string().
-
-2002-11-16  Murray Cumming  <murrayc@usa.net>
-
-	* libxml++-1.0.pc.in: More corrections. This was hopelessly broken
-	before.
-
-2002-11-16  Murray Cumming  <murrayc@usa.net>
-
-	* libxml++-1.0.pc.in: Corrected typo.
-
-2002-11-16  Murray Cumming  <murrayc@usa.net>
-
-	* docs/reference/Doxyfile: Used doxywizard to mark the Recursive
-	option, so it reads the libxml++/parsers directory too.
-
-2002-11-16  Murray Cumming  <murrayc@usa.net>
-
-	* Attribute, Node: Added Doxygen class comment block. Changed some
-	something * to something*.
-
-2002-11-16  Murray Cumming  <murrayc@usa.net>
-
-	* libxml++/node.[h|cc]: Added parameter names. Made const and non-const
-	overloads of children() method.
-	* libxml++/parsers/domparser.[h|cc]: Added const get_root_node() const
-	overload.
-
-2002-11-16  Christophe de Vienne <cdevienne@alphacent>
-	* libxml++/parsers/*: renamed method Parser::parse to
-	Parser::parse_file
-
-2002-11-16  Christophe de Vienne <cdevienne@alphacent>
-	* libxml++/parsers/saxparser.[h|cc]: rewritten
-	SaxParser::parse(filename) and SaxParser::parse_memory(string).
-	They both use a SaxParser::parse()
-	method. The parse_chunk and finish methods has been removed.
-	* example/sax_parser/parser.cc: minor bugfix: the Attribute pointer
-	was printed instead of the value.
-
-2002-11-16  Christophe de Vienne <cdevienne@alphacent.com>
-	* Property: has been renamed to Attribute. However, the "properties"
-	token has been kept when speaking of all the attributes of a node,
-	as in the libxml library.
-	* node.cc: rewritten a few loops so they have a more 'c++' looking.
-	rewritten some portions of code where an attribute is searched by name.
-
-2002-11-15  Murray Cumming  <murrayc@usa.net>
-	* Changed e.g. std::string &something to std::string& something,
-	using regexxer.
-
-2002-11-15  Christophe de Vienne <cdevienne@alphacent>
-	* example/sax_parser/parser.cc: #included <iostream>
-
-2002-11-15  Christophe de Vienne <cdevienne@alphacent>
-	* libxml++/parsers/saxparser.cc: #included cstdarg instead of stdarg.h
-	to follow the c++ standard. #included <iostream> to have std::cerr - it's
-	needed on strict c++ compiler (g++ 3.2 for instance).
-	* example/dom_parser/main.cc: #included <iostream>
-
-2002-11-15  Murray Cumming  <murrayc@usa.net>
-
-	* libxml++/parsers/saxparser.cc: #included stdarg.h - it seems to
-	be necessary with some compilers.
-
-2002-11-15  Murray Cumming  <murrayc@usa.net>
-
-	* DomParser:: Added get_encoding() and write() methods.
-	* Removed Tree - Use DomParser instead.
-
-2002-11-15  Murray Cumming  <murrayc@usa.net>
-
-	* SaxParser now inherits from Parser, with parse() and parse_memory()
-	methods.
-	* Added example/sax_parser example, but the start_element callback
-	doesn't seem to be called.
-
-2002-11-15  Murray Cumming  <murrayc@usa.net>
-
-	* Parser, DomParser: Added parse_memory() method.
-	* Node::children(): Removed bad early-optimisation hack - it returned
-	a static function variable instead of returning by value. This meant
-	that >1 results of children() could not be used simultaneously.
-	For instance, this meant that it could not be called recursively.
-
-2002-11-12  Murray Cumming  <murrayc@usa.net>
-
-	* Node, Property: Used explicit keyword on constructors.
-
-2002-11-12  Murray Cumming  <murrayc@usa.net>
-
-	* Added parsers directory.
-	* Renamed Parser to SaxParser.
-	* Added DomParser, intended as a replacement for Tree, but that has
-	not yet been removed. I don't intend to implement the libxml-1
-	compatibility stuff.
-	* Added examples directory structure, with one tiny dom_parser example.
-
-2002-11-12  Christophe de Vienne <cdevienne@alphacent.com>
-	* node.[h|cc]: name() method now return a reference.
-	* Tree/Node: The readnode and writenode functions have been removed
-	and transfered somehow into Node as a new constructor and write().
-	The libxml++-private.[h|cc] has been removed.
-
-2002-11-12  Murray Cumming  <murrayc@usa.net>
-
-	* Parser: It's no longer a templated type - to provide your own
-	callback implementations you can now just derive your own parser and
-	override the on_*() methods.
-
-2002-11-12  Murray Cumming  <murrayc@usa.net>
-
-	* Moved implementation into the .cc files.
-        * Changed n, v and p parameter names to name, value and properties.
-
-2002-11-12  Murray Cumming  <murrayc@usa.net>
-
-	* Split the single xml.[h|cc] files into node, property, tree and
-	parser files, with a libxml++.h header file that includes them all.
-	* Removed the XML prefixes from type names - we don't need it because
-	we use a namespace now.
-	* Placed typedefed lists and map inside their classes. For instance,
-	XMLNodeList is now xmlpp::Node::NodeList.
-	* Node::children(): Use !(n.empty()) instead of (n.length() == 0), for
-	perfomance.
-	* Tree: changed fn parameter names to filename.
-
-2002-11-12  Christophe de Vienne <cdevienne@alphacent.com>
-	* AUTHORS: Added Murray Cumming to the contributors
-
-2002-11-08  Christophe de Vienne <cdevienne@alphacent.com>
-	* libxml++/xml.cc: corrected _line initialisation in XMLNode::XMLNode(const XMLNode *from)
-
-2002-11-08  Christophe de Vienne <cdevienne@alphacent.com>
-
-	* libxml++/xml.cc: Test if doc encoding is not null before
-	reading it (thanks to Marcel Bosc).
-
-2002-11-05  Murray Cumming  <murrayc@usa.net>
-
-	* Added docs/reference/. Run make in this directory to generate
-	reference documentation with doxygen.
-	* libxml++/xml.h: Removed macros around namespace - all compilers
-	must now support namespaces.
-	* libxml++/xml.[h|cc]: Replaced (void) with () - it's not necessary
-	in C++.
-
-2002-11-05  Murray Cumming  <murrayc@usa.net>
-
-	* libxml++/Makefile.am and configure.in: Implemented shared library
-	interface versioning.
-
-2002-11-05  Murray Cumming  <murrayc@usa.net>
-
-	* Put source code in libxml++ directory, ready for it to be split up
-	into separate files. Client code should now include
-	libxml++/xml++.h rather than just xml++.h.
-
-2002-11-05  Murray Cumming  <murrayc@usa.net>
-
-	* Headers are now installed in a versioned directory, to allow
-	coexistence with future major versions of libxml++. You may need to
-	remove the previously installed xml++.h file.
-	* Library name changed to libxml++-0.1, to be changed to libxml++-1.0
-	when libxml++ stabilizes its API. This is also to allow future versions
-	to be parallel installed.
-	* Added pkg-config file as a simpler and more maintainable alternative
-	to the -config file and m4 script.
-
-Version 0.14
-	* Ported to g++ 3.2. The code should now also compile on compilers which are a bit more strict about c++ than previous versions of g++
-	* Added method XMLNode::line() wich returns the line number of a non content node in the source file.
-	* Added encoding file support through XMLTree::encoding() and XMLTree::set_encoding() methods
-	* Replacement of hash_map by map for node properties lists, since it has been reported to be faster, and to simplify porting to other plarfoms.
-	* libxml++ classes has been put in a separated namespace, libxmlpp. If you don't want namespace, just undefine the LIBXMLPP_USE_NAMESPACE
-	* encoding and compression settings are now loaded at parsing of file/buffer.
-
-
-Version O.12 to 0.13
-	No Changelog.
-
-Version O.11
-	* Modified interface to allow for more complete coverage of possible uses of XML files.
-
-Version O.10
-	* Added SAX parser.
-
-Version O.2 to 0.9
-	No Changelog.
-
-Version O.1
-	* Original release.
