Override, rather than overload.  Normally, yes.  Unless
you just want the list of links from an HTML page, in
which case this simple script will do it:

import htmllib
import formatter

parser=htmllib.HTMLParser(formatter.NullFormatter())
parser.feed(open('myfile.html').read())
parser.close()

print parser.anchorlist


Now, if, instead of just instantiating HTMLParser, you
instantiate a class of your own that derives from it
and overrides the methods you're interested in, then
you can do different things.  But it's hard to give a
meaningful example without knowing what it is you
want to do.  For some tasks, building your own
formatter-class and using the plain parser-class from
htmllib may be a simpler way, too.
