Actually, PyXML now incoporates 4DOM as its DOM library.  The old code
mentioned above is no longer maintained by anyone.

Here is code given in the article

import sys
from xml.dom import core
from xml.dom.html_builder import HtmlBuilder

# Construct an HtmlBuilder object and feed the data to it
b = HtmlBuilder()

# Get the newly-constructed document object
doc = b.document

# Output it as XML
print doc.toxml()

And here is how it would look in PyXML or 4DOM

import sys
from xml.dom import ext
from xml.dom.ext.reader import HtmlLib

#Create a reusable reader object
reader = HtmlLib.Reader()

#Construct a DOM from stdin
doc = reader.fromStream(sys.stdin)

#Output the HTML as XHTML
