You could subclass HTMLParser.HTMLParser and override handle_starttag
and handle_endtag (also, if needed, handle_charref, handle_entityref,
and last but not least handle_data -- that's assuming that while you
only talk about processing _tags_ you may in fact also want to process
references and text nodes... possibly handle_comment, too, btw).
