Parsing XML in PHP5

I'm particularly looking for advice from anybody who is a Reflexive affiliate. Anyway...

I want to use their XML feed for my site. The path to their XML feed points to an .ras file - what's this?

Also, is it possible to do this using SimpleXML? How? I don't understand how to retrieve any info from this .ras file.

can you post the URL?

No, its restricted access by IP address. General advice on parsing XML will do, since I've tried it with regular XML and can't get anywhere with that either.

SoapAPI? This will point you in the right direction.

Never mind - sorted it with SimpleXML.

Royal pain in the arse but I got it working at last.
