that should be 2.2 and later, right?

note that if you don't use do/start/end handlers, you can support
earlier versions by falling back on SGMLParser:

try:
    from HTMLParser import HTMLParser
except ImportError:
    from sgmllib import SGMLParser
    # hack to use sgmllib's SGMLParser to emulate 2.2's HTMLParser
    class HTMLParser(SGMLParser):
        # the following only works as long as this class doesn't
        # provide any do, start, or end handlers
        def unknown_starttag(self, tag, attrs):
            self.handle_starttag(tag, attrs)
        def unknown_endtag(self, tag):
            self.handle_endtag(tag)
