Unless you have a really compelling reason to parse HTML with ANTLR,
I'd recommend using something like Jericho HTML or TagSoup instead.

Otherwise, you can check out the XML parsing example in the wiki, as
it's probably the best route to an HTML parser.

Sadly, any use of predicates or backtracking seems to make using the
nifty tools for ANTLR kinda hard...

I'm a tad crazy, and am working on a HTML-ish parser using ANTLR, but
it's still pretty rough.
