I need to parse a large (>800MB) XML file from Jython. The XML is not deeply nested, containing about a million relevant elements. I need to convert these elements into real objects. 
I've used nu.xom.* successfully before, but now that I've switched from Java to Jython, the library fails with the following message:

The parser has encountered more than
  "64,000" entity expansions in this
  document; this is the limit imposed by
  the application.

I have not found a way to fix this, so I probably have to look for another XML library. It could be either Java or Jython-compatible Python and should be efficient. Pythonic would be great, nu.xom.* is simple but not very pythonic. Do you have any suggestions?
there is a lxml python library, that can parse large files, without loading data to memory.
but i don't know if i jython compatible
