The standard answer is to use tidy to convert to XHTML.
http://tidy.sourceforge.net/ and then parse it with an
ordinary XML parser.
The possibly wacky answer is to use Javascript in a browser if
at all possible. For better or worse (mostly worse!) the browser
vendors have worked hard to "accept the flaws and build a
tree anyway", and then expose that tree with the DOM API. You
can essentially pretend the ill-formed HTML is XML and use the
XML Core DOM to work with it. You might need to use some
server-side PHP or whatever to grab web pages, filter in the
Javascript code, and feed it to the browser to work around
the browser/Javascript "sandbox" limitations.
