/**
14+
* Extracts the 'subid' from a PubSub subscription response.
15+
*
16+
* For example, if we sent a PubSub subscription request for node "princely_musings",
17+
* and the server returned this response:
18+
*
19+
* <iq type='result' from='pubsub.shakespeare.lit' to='francisco@denmark.lit/barracks' id='sub1'>
20+
* <pubsub xmlns='http://jabber.org/protocol/pubsub'>
21+
* <subscription
22+
* node='princely_musings'
23+
* jid='francisco@denmark.lit'
24+
* subid='ba49252aaa4f5d320c24d3766f0bdcade78c78d3'
25+
* subscription='subscribed'/>
26+
* </pubsub>
27+
* </iq>
28+
*
29+
* Then this method would return "ba49252aaa4f5d320c24d3766f0bdcade78c78d3".
30+
*
31+
* It is common to store the subid as it often a required attribute when unsubscribing.
