programming flash

Hi there!
I?m having a problem loading a XML. Here is the code:

function loadXML(url:String):void {
var loader:URLLoader = new URLLoader();
loader.addEventListener(Event.COMPLETE, loadXMLComplete);
loader.load(new URLRequest(url));
}
loadXML(“galeria.xml”);

function loadXMLComplete(e:Event):void {
contentXML=new XML(event.target.data);
trace("IM here " + contentXML);

}

And here is the error:
1120: Access of undefined property contentXML.
