replacing it with & fixed the XML error. Thanks!

Interesting.. So to be consistent with proper XML formatting, should the server
hosting the XML file convert the & into & ?

I certainly feel like I'm missing something... Although I'm a bit at odds as to how
to troubleshoot this new file.
I no longer get the errors, but I'm not getting the results I'm looking for either.
The updated script is running here:
http://www.airdiv-cupe.org/portal/newsfeed_new_parser.php
I've also attached the full script (since I've made some changes to it).
Any additional help would be appreciated.
