Consider using lxml.

http://codespeak.net/lxml/

untested:

   import lxml.etree as et
   parser = et.HTMLParser()
   doc = et.parse(url, parser)

   doc.xslt(et.parse("mf-extract.xsl"))

   for el in doc.getiterator("*"):
       if '{' not in el.tag:
           el.tag = "{http://www.w3.org/1999/xhtml}"; + el.tag
