Thanks!
Hi Chris!
Could you be a little more concrete?
Thanks!
You do realise that pyexpat has a limitation of 8192 bytes between xml
tags - if your parse string is longer than this, it will fail.  You can
recompile your expat parser to accept larger sizes, but this drastically
affects performance.

Buff! Complicate

There are any out-of-the-box solution on Zope?

I mean: there are any other xml library on a standard Zope installation?

Thanks!
