Referencing Text Field within Custom Class

programming flash
1

I have set up two classes, one is the DocumentClass and it imports a custom class i have made called XMLLoader. The problem is I want to change the value of a dynamic text field on the stage with the instance name xml_txt from within the XMLLoader class…


package classes
{
    import flash.display.MovieClip;
    import classes.XMLLoader;
    
    public class DocumentClass extends MovieClip
    {
        public function DocumentClass():void
        {
             var xml:XMLLoader = new XMLLoader();
        }
    }
}



package classes
{
    import flash.events.*;
    import flash.net.URLLoader;
    import flash.net.URLRequest;
    
    public class XMLLoader
    {
        var req:URLRequest = new URLRequest("myXML.xml");
        var loader:URLLoader = new URLLoader();
        
        public function XMLLoader():void
        {
            loader.addEventListener(ProgressEvent.PROGRESS, loadProgress);
            loader.addEventListener(Event.COMPLETE, loadComplete);
            loader.load(req);
        }
        
        private function loadProgress(event:ProgressEvent):void
        {
           var percent:Number = ( 100 / event.bytesTotal ) * event.bytesLoaded;
           trace(Math.round(percent));
        }

        private function loadComplete(event:Event):void
        {
            var newLoader:URLLoader = URLLoader(event.target);
            trace(newLoader.data);
        }
    }
}
