Using Xml in flash problems

I am getting this error code :
TypeError: Error #1006: value is not a function.
at ProjectMain_Scene5_fla::MainTimeline/frame1()

I am basically trying to load my xml file in flash and keep getting that error.

My code is:
stop();

btnPlay.addEventListener(MouseEvent.CLICK, clickedPlay2);

var my_xml = new XML();

my_xml.load(“I:\Final Year Project
umericGame.xml”);

function clickedPlay2(event:MouseEvent):void
{
trace (“play”);
}

Can anyone help please?
