Can you give a short example of a what you are doing to get this error to show up? I've done some basic testing and can't get the compiler to throw an issue. I'd like to be able to reproduce before I merge this.

Hi!

If i recall, you only need to add a template tag within the "main" template tag, e.g.:

<template web>
    <div>
        <template v-if="someCondition">
            <p>Something</p>
            <button>My button</button>
        </template>
        <template v-else>
            <p>Something else</p>
            <button>My other button</button>
        </template>
    </div>
</template>

<template native>
    <StackLayout>
        <template v-if="someCondition">
            <Label text="Something"/>
            <Button text="My button"/>
        </template>
        <template v-else>
            <Label text="Something else"/>
            <Button text="My other button"/>
        </template>
    </StackLayout>
</template>

I'm going to reject the PR as I could not reproduce this. However, I have left your regex statement in v0.2.0 as commented out in case we need to revisit this.

Try 0.2.0 and see if this still happens. It may very well happen for you, but in my test, I could not get any error to come up. This may be because with with 0.2.0, we are updating everything to Nativescript 6.1 and more importantly, to NS-Vue 2.4.0.
