Extracting Data from FRC-Spy

[Dkt01]

Hi everyone,
I want to use the xml data from FRC-Spy to automatically update match results on our team website. My issue is I don't know how to extract the xml data from FRC-Spy. I know you should be able to add "xml=2" to the end of the address to get all the match results in xml, but I can't manage to get the actual information off the website. I'm using php with simple xml.
So far this is what I'm having trouble with:

PHP Code:

$allmatches = simplexml_load_file("http://www.chiefdelphi.com/forums/frcspy.php?xml=2.xml"); 


This never actually loads the file so that I can use it. The server is running php 5.2.17.

Any suggestions or example code would be great, since I am pretty new to php.
Also, if I need to clarify anything, let me know.
