Hello Fabian,
This was very helpful. Thanks for letting me know about this little glitch.
It almost resolves the problem that I was having. Now I no longer get xml
errors. However, I'm not able to output the XML either.
Any suggestions would be appreciated. The updated code is available here:
http://www.airdiv-cupe.org/portal/newsfeed_new_parser.php
And I've included the full script in the email (at the very bottom of this message).
Thanks.
Mike
