XML from external class

programming flash

I am having some difficulties loading XML from an external class. I would like to place the firstChild into a Dynamic Text Box. In my Flash movie the text box is labeled LevelTitle. This is my code at the moment:

class SelectTest extends XML {
	var Testlist: XML;
	var curContainer:XMLNode
	
	function SelectTest() {
		var Testlist = new XML;
		Testlist.load("TestList.xml");
		Testlist.ignoreWhite = true;
		Testlist.onLoad = getTest()
		
	}

	function getTest() {
		trace ("success");
		var LevelTitle= Testlist.firstChild
	 	trace (LevelTitle);
	}
}

It always traces “sucess” leading me to believe that the xml is loading successfully, but when I try to trace LevelTitle, (or Testlist.firstChild, or Testlist.toString()) I always get undefined. What am I doing wrong?
