jython lacks working xml processing modules?

Hmm, pity about that. To be honest, I'm not going to try and make it
work. Any time I need XML processing in jython, I use native Java xml
parsers, such as Xerces. I think most jython users work the same way.

I kind of figured that. My focus with the question was "Why do you
need a tree model"? Do you need to data extraction, structure
validation, xpath/xslt, etc?

If this helps, here is a jython snippet that creates a DOM using
Apache Xerces.

from  java.io  import StringReader

import  org.xml.sax as sax
import  org.apache.xerces.parsers.DOMParser as domparser

if __name__ == "__main__":
  parser = domparser()
  document = """<doc><a href="http://www.python.org"/></doc>"""
  parser.reset()
  documentIS = sax.InputSource(StringReader(document))
  parser.parse(documentIS)
  domtree = parser.getDocument()
  results = domtree.getElementsByTagName('a')
  for ix in range(results.getLength()):
    print "Link found: uri=%s" % results.item(ix).getAttribute('href')
