Yes, this wasn't intended as the final patch. If it's not wanted right 
now, that's fine too. I just wanted to get it on the record as possibly 
something useful when we do come to reconsider the whole mess. Getting 
to grips with the libxml2 API is no fun, and it's better not to have to 
repeat it if possible ;-)

The tokens were chosen with some care to be such that no whitespace 
tolerance would be needed (or correct). XML is case sensitive, so that's 
not an issue either.
