as3加载外部xml文件解析代码

//LoadXml---------------------------------------------------------
var LoadXML:XML = new XML();
var exxml:XML;//set variable exxml as xml data type
var loader:URLLoader = new URLLoader();//set variable  loader as URLLLoader data type
var requestt:URLRequest=new URLRequest("as.xml");
//set variable  requestt as URLRequest data type with parameter(location of the external xml file)
loader.load(requestt);
//实例loader用方法load读取变量URLRequest实例,(读取路径)
loader.addEventListener(Event.COMPLETE, image_num_fromXML_OnComplete);
//实例loader注册侦听(事件为Event.COMPLETE,调用onComplete函数处理)
//----------------------------------------------------------------------


function image_num_fromXML_OnComplete(event:Event):void {

	//从XML文件中载入图片数量--------------------------------------------
	loader.removeEventListener(Event.COMPLETE, image_num_fromXML_OnComplete);
	exxml=new XML(loader.data);
	LoadXML=exxml;
	trace(LoadXML.children().length());//显示xml的children的数量 



	trace(LoadXML.photo.@thumbnail[1]);//直接读取第i个项的url值

}
