package  {
	
	import flash.display.MovieClip;
	import flash.net.URLLoader;
	import flash.net.URLRequest;
	import flash.net.URLLoaderDataFormat;

	import flash.events.IOErrorEvent;

		public function Main() {
			var xmlLoader:URLLoader = new URLLoader();
			xmlLoader.dataFormat = URLLoaderDataFormat.TEXT;
			xmlLoader.addEventListener(Event.COMPLETE, onXmlLoader_COMPLETE);
			xmlLoader.addEventListener(IOErrorEvent.IO_ERROR , onXmlLoader_IO_ERROR);
