I see.. that does make some sense. So just now I did the following:-
Downloaded and installed expat 2.0
Re-compiled Apache
Re-compiled Python (I switched to 2.4.3 as well)
Re-compiled the latest PyXML (0.8.4)
Re-compiled mod_python
Restart apache...
Which did not change anything. Then I read Graham's post, and read the article, and discovered even though I had installed a new expat, my old libraries were still being used, so did some library moving around and re-compiled Apache and now it works great.

Thank you very much for the help guys, much appreciated.
I hope the weather is nice in Liverpool & Aus! In Kent (South east England) its miserable and rainy... joy!

Thank you once again for resolving this issue,
Kind regards,
Dom

As pointed out by someone else, it is probably a versioning issue with expat. See the following article for how to debug which versions of expat are being
used and thus whether there might be a conflict.

Hi,
I'm in the middle of re-writing an application that uses mod_python for serving to the web, and have decided to switch to an XML model to store some information, however, I encountered an issue that I don't quite understand, see this short example that isolates the problem:

from xml.sax import make_parser, SAXException

def index(req):
        req.write("Hello...")

        try :
            test = make_parser()
        except SAXException:
            req.write("Failed")

        req.write("\n Can you see me?")

When I try to view this page I just get the "Hello..." text and then nothing else, the program seems to terminate at the make_parser () call. Which is most confusing. Run locally from the command prompt there are no problems. I was using mod_python 3.1.4 in a hope to fix the problem I downloaded 3.2.8, but this did not change anything. Here is my Apache info (Apache/2.0.54 (Unix) mod_python/3.2.8 Python/2.4 PHP/5.0.4)
Does anyone else get this problem?
Could this be a potential bug, I'm not quite sure what would be causing it though, some kind of serialization problem?

Regards,
Dominic Orchard
