Is there a way in XSLT to convert a string to XML?
That's called parsing. As Michael said XPath 3 drafts include a
parse-xml function, or many xslt 1 and 2 processors have such an
extension function, or, if you are feeling strange you could write
a parser in xslt.
Is there any possibility of getting the XPath 3 functions to _not_
require balanced trees?
I suspect xpath3 is virtually done but you can put in a feature request
via bugzilla for xpath n (I'm not on the working group, so can't say how
well received that would be:-)
In practice you can do something along those lines already as (as for
top level document parsing) many products allow the xml parser to be
specified external to the xslt, and as long as the parser returns
xml-like sax parse events xpath doesn't really care what the input
syntax looks like, so you can supply an html parser (tag soup for
example for java xslt processors) which will consume (and "fix up")
markup that is not well formed.
The only time I've had to use this kind of functionality, it was to
take a horrible mess of semi-colon-space separated link-like things
embedded in a mass of text where the text could be decorated with
various bits of markup -- bold, italic, "term", actual link markup of
various flavours -- and serialize it so it could be split at the
semi-colon spaces.
The results of tokenization had to go back into XML and be
processed, and the tokens certainly weren't balanced trees.
It's not that hard to write a function to do this, but it would be
nice to not have to.
