Retrieve parameter from an Object (Xml reader)

Question

hi,
I have 2 classes and im trying to receive the variable "xmlResult" from the object my_XML, but its always null.
I understand that is an asynchronous problem, but I dont know how to resolve this.
Thanks for you help.
XmlClass.as
package  {
   import flash.net.URLLoader;
   import flash.net.URLRequest;
   import flash.events.Event;
   import flash.events.EventDispatcher;
   import flash.display.Loader;
   import flash.events.MouseEvent;
   import flash.display.Sprite;
   import flash.display.SimpleButton;
   import flash.text.TextField;
   public class XmlClass  extends Sprite{
      public var loader:URLLoader;
      public var xmlResult:XMLList;
      public var pathXml:String;
        public function XmlClass(pathXml:String) {
         retrieveData(pathXml);
         //trace(xmlResult);
      private function retrieveData(pathXml:String):void{
         loader=new URLLoader();
         loader.addEventListener(Event.COMPLETE,onCompleteLoading);
         //var urlRequest:URLRequest= new URLRequest(pathXml);
         loader.load(new URLRequest(pathXml));                      
      private function onCompleteLoading(e:Event):void{
         xmlResult=(XMLList(e.target.data));
Main_1.as
package  {
   import flash.display.MovieClip;
   import flash.events.Event;
   public class Main_1 extends MovieClip{
      //private var xmlList:XMLList;
      private var my_Xml:XmlClass;
      public var resultXml:XMLList;
      //PATH TO XML File
      private var pathXml:String="assets/color.xml";
      public function Main_1() {
         createXml(pathXml);
      public function createXml(pathXml){
         my_Xml=new XmlClass(pathXml);
         trace(my_Xml.xmlResult);
}

I suppose the simplest way would be to redispatch Event.COMPLETE. Something like this:
<SNIP>
  public class XmlClass  extends Sprite{
      public var loader:URLLoader;
      public var xmlResult:XMLList;
      public var pathXml:String;
        public function XmlClass(pathXml:String) {
         retrieveData(pathXml);
         //trace(xmlResult);
      private function retrieveData(pathXml:String):void{
         loader=new URLLoader();
         loader.addEventListener(Event.COMPLETE,onCompleteLoading);
         //var urlRequest:URLRequest= new URLRequest(pathXml);
         loader.load(new URLRequest(pathXml));                      
      private function onCompleteLoading(e:Event):void{
         xmlResult=(XMLList(e.target.data));
          dispatchEvent(e);
Main_1.as
package  {
   import flash.display.MovieClip;
   import flash.events.Event;
   public class Main_1 extends MovieClip{
      //private var xmlList:XMLList;
      private var my_Xml:XmlClass;
      public var resultXml:XMLList;
      //PATH TO XML File
      private var pathXml:String="assets/color.xml";
      public function Main_1() {
         createXml(pathXml);
      public function createXml(pathXml){
         my_Xml=new XmlClass(pathXml);
                    if(my_Xml.xmlResult){doXMLDataReady();}
                   else{
               my_Xml.addEventListener(Event.COMPLETE, onXMLDataReady);
     function doXMLDataReady(){trace(my_Xml.xmlResult);}
     function onXMLDataReady(event:Event)
        my_Xml.removeEventListener(Event.COMPLETE, onXMLDataReady);
               doXMLDataReady();
