XML loader class

programming flash
1

Hi everyone,

I’m just trying to write an XMLLoader class, that I can use over and over, and passing a string of the xml url to load.

the XMLLoader class is:


package classes
{
	import flash.display.Sprite;
	import flash.events.Event;
	import flash.net.URLLoader;
	import flash.net.URLRequest;
	
	public class XMLLoader extends Sprite
	{
		private var _xmlData:XML;
		private var loader:URLLoader;
		
		public function XMLLoader(xmlURL:String)
		{
			var xmlRequest:URLRequest = new URLRequest(xmlURL);
			loader = new URLLoader (xmlRequest);
			loader.addEventListener(Event.COMPLETE, onComplete);
			trace("XML Loader init()");
		}
		private function onComplete(event:Event):void
		{
			_xmlData = XML(loader.data);
			trace("xml is loaded");
		}
		public function get xmlData():XML
		{
			var _data:XML = _xmlData;
			return _data;
		}
	}
}

the main class is XMLSetup :


package classes
{
	import flash.display.Sprite;
	import flash.events.Event;
	public class XMLSetup extends Sprite
	{
		private var loader:XMLLoader;
		private var xmlURL:String = "xml/test.xml";
		
		public function XMLSetup()
		{
			init();
		}
		private function init():void
		{
			loader = new XMLLoader(xmlURL);
			trace(loader.xmlData);
			trace("XMLSetup init()");
		}
	}
}

now when I run a test it outputs:

XML Loader init()
null
XMLSetup init()
xml is loaded

so basically trace(loader.xmlData);
is being called before the xml is loaded; returning null.

what is the best way of fixing this? is there any event that I can fire for the main class to know that intance has loaded the xml? aor what is the best way to do this?

thanks
