tools(xml_tools): fixed `<div>` unwrapping + added `parse` instance:
`<div>` unwrapping could fail when a text node was a sibling of the top element (could
easily happen ith a `\n` line feed added by an editor). This is fixed by filtering on
IElement with `elements()`.
A `parse` instance has been added as it is not necessary to create a new `ElementParser`
each time that we want to parse something.
