What do you mean exactly? Do you want to manipulate the HTML document in the
browser while displaying it or do you want to change an in-memory
representation of a HTML document (read from and written to a file again perhaps)?

The former would have to be done with JavaScript and you should probably ask on
a JavaScript list how to do this (though I'd highly recommend you look at the
MochiKit JavaScript library <http://mochikit.com/>).

For the latter, you could parse the HTML into a DOM representation and then use
DOM methods to add and change Nodes in it. There are several libraries in
Python that allow you to do so. A recent favourite with the Python community is
ElementTree <http://effbot.org/zone/element.htm>, though you might have to
clean up the HTML input a little bit before you feed it into ElementTree (e.g.
with BeautfulSoup <http://www.crummy.com/software/BeautifulSoup/>.
