Re: [Jython-dev] Jython 2.5 alpha 0

SourceForge Headquarters 225 Broadway Suite 1600 San Diego, CA 92101 +1 (858) 454-5900

Jim,

I am using Java's org.xml.sax and not Jython's xml.sax.

I made the code available at http://code.google.com/p/jython-elementtree.
Only elementtree/ElementTree.py and elementtree/JythonHotfix.py are of 
interest.
The other files are identical to what is found in the elementtree 1.3 
alpha svn repository:
http://svn.effbot.org/public/tags/elementtree-1.3a3-20070912/

I don't guarantee anything beyond the 'jython2.5a0 selftest.py' good score
at this point ... I also guess that my ElementTree target version -- 
1.3, still
in alpha and not the one in Python 2.5 standard lib -- may be an issue for
direct inclusion in Jython 2.5.

However, if you feel that this work can be adapted for the Jython 2.5
standard library, please go ahead !

Regards,

SB
