First point: you're using a noNamespaceSchemaLocation, whereas my
example showed a schemaLocation attribute. I'd have to run your
code to see what happens here.

You seem to have commented all of the interesting lines out.

How do you know ? You don't seem to have set an error handler,
or enabled the correct features, due to the comments above, and you
don't seem to be checking $@.

I may be misunderstanding what you're doing in the code, as what
you've shown above looks rather odd.

Two points

1. Please don't send HTML based messages, as not all readers
support HTML

2. I don't know what you mean by "the script exists there".
It seems to me that the script doesn't exist there, as you've
commented it out.
