It's likely that the HTML isn't well-formed XML, so you're going to have to
extract it as a string, put it through the tidy utility, parse it, and get
it back into the stylesheet in tree form before you can manipulate it at the
node level. 

I would tend to do this as a non-XSLT stage in a processing pipeline; you
could also do it by calling out to an extension function.
