Accessing XML data from a different class

Question

Hi all,
I have an xml class that loads xml data, I need to access the data from another class. I have imported the xml classinto the new class and created a new instance of it. However when I try to access the xml data it is coming back as null. I understand this is almost certainly because when it is called the xml data hasn't completed it's load. How can I get round this?
xml class:
package {
    import flash.xml.*;
    import flash.events.*;
    import flash.net.*
    import flash.display.*
    public class xml extends MovieClip
        public var xmlRequest:URLRequest;
        public var xmlLoader:URLLoader;
        public var xmlImages:XML;
        public function xml()
            xmlRequest = new URLRequest("images.xml");
            xmlLoader = new URLLoader(xmlRequest)
            xmlLoader.addEventListener(Event.COMPLETE, xmlLoaded);
            xmlLoader.load(xmlRequest);
        private function xmlLoaded(event:Event):void
            trace(xmlLoader.data);
            xmlImages = new XML(xmlLoader.data);
Thanks in advance

One of the ways:
package {
     import flash.xml.*;
    import flash.events.*;
    import flash.net.*
    import flash.display.*
    public class XMLLoader extends EventDispatcher
          public var xmlRequest:URLRequest;
          public var xmlLoader:URLLoader;
          public var xmlImages:XML;
          public function XMLLoader()
          public function loadXML(url:String):void {
               xmlLoader = new URLLoader()
               xmlLoader.addEventListener(Event.COMPLETE, xmlLoaded);
               xmlLoader.load(new URLRequest(url));
          private function xmlLoaded(event:Event):void
               trace(xmlLoader.data);
               xmlImages = new XML(xmlLoader.data);
               dispatchEvent(event);
Usage:
var xmlLoader:XMLLoader = new XMLLoader();
xmlLoader.addEventListener(Event.COMPLETE, onXMLLoad);
xmlLoader.loadXML("images.xml"):
function onXMLLoad(e:Event):void{
     trace(xmlLoader.xmlImages);
