Please send a patch with whatever come up with, so others can make use
of it. I've already added Data.HTML.TagSoup.Tree to the latest darcs
version, which does as well as it can with tag matching, but is
entirely strict. Having a lazy version would be great.

I've been talking to the Java tagsoup author (http://tagsoup.info),
which does very clever processing of HTML to make it as structured and
normalised as possible. He said:

There is also some slides on his website (at the bottom) which detail
the Java TagSoup approach to reconstructing HTML, and have obviously
had a lot of thought put into them!
