There has been support for Jython in the ElementTree subversion repository since 2005 in the form of a  file named JavaXMLTreeBuilder.py .

Below is a  sample of its explicit use as a parameter with the version 1.2.7 of ElementTree, by passing a TreeBuilder instance to the ElementTree.parse as the default parser. Of course you can set it as the default parser in ElementTree.py by modifying the DefaultParserAPI line to be:

parser_api = default_parser_api = DefaultParserAPI(parser=JavaXMLTreeBuilder())
