<p class=MsoNormal>Hi,<br>
<br>
Seo has already done a basic pyexpat wrapper. He posted about it in:<br>
<br>
<a
href="http://lists.ironpython.com/pipermail/users-ironpython.com/2005-November/001227.html">http://lists.ironpython.com/pipermail/users-ironpython.com/2005-November/001227.html</a><br>
<br>
And it can be found at:<br>
<br>
<a href="http://sparcs.kaist.ac.kr/~tinuviel/fepy/old/pyexpat.py">http://sparcs.kaist.ac.kr/~tinuviel/fepy/old/pyexpat.py
</a><br>
<br>
I have used this with ElementTree. There are limitations like iterparse<br>
doesn't work and if the XML you are parsing contains an empty element<br>
i.e <doc /> it fails. I have modified Seo's pyexpat.py to handle the <br>
second limitation and have included the source in this email. I have<br>
used this for my elementtree requirements but the XML I parse is simple<br>
so there may be other as yet undiscovered issues.<br>
<br>
Regards<br>
<br>
Mark<br>
