Thanks optik but modifying the .htaccess file for that directory to something like AddType application/x-httpd-php .xml would mean the entire xml file would be processed and there are many formatitng issues that would have to be addressed. I would get many unexpected T_STRING issues. For example it would throw an error on the first line <?xml version='1.0'?>
Well, you wouldn't, like any PHP file, it would only execute PHP between <?php and ?>. But it's a bit of overkill to mod the entire system for a few files with the Flash player. Just output XML from a script, also works fine, solution above.
