TagSoup is a SAX-compliant parser written in Java that, instead of
parsing well-formed or valid XML, parses HTML as it is found in the wild: nasty
and brutish, though quite often far from short. TagSoup is designed for people
who have to process this stuff using some semblance of a rational application
design. By providing a SAX interface, it allows standard XML tools to be
applied to even the worst HTML.
