Having a big problem getting xml into as3 and working with it

Hi everyone, just thought I would christen my kirupa.com forum membership by hoping somebody could stop me from having a massive brain aneurysm…

so I have been following the brilliant tutorial on working with xml in as3 and I follow it perfectly but when I try to use my own code it wont work and I am getting this really annoying error:

TypeError: Error #1085: The element type “body” must be terminated by the matching end-tag “</body>”.
at testing2_fla::MainTimeline/LoadXML()
at flash.events::EventDispatcher/dispatchEventFunction()
at flash.events::EventDispatcher/dispatchEvent()
at flash.net::URLLoader/onComplete()

emphasis on the first line I would say. I am trying to load in a php file, would this matter as oppose to loading in an xml file directly?
