        private var xmlLoader:URLLoader;        private function loadXML():void{            //设置外部XML的路径            var request:URLRequest = new URLRequest("TestInfo.xml");            xmlLoader = new URLLoader();            try {                xmlLoader.load(request);            }            catch (error:SecurityError)            {                trace("A SecurityError has occurred.");            }            xmlLoader.addEventListener(IOErrorEvent.IO_ERROR, xmlloader_ioError);            xmlLoader.addEventListener(Event.COMPLETE, xmlloader_complete);        }        private function xmlloader_complete(event:Event):void {            var externalXML:XML;             var _name:String;                try {                    externalXML = new XML(xmlLoader.data);                    //此处为 获取XML里第一个节点里的属性Name的值；                    _name= externalXML.elements()[0].attribute("Name");                    //sendData();                } catch (e:TypeError) {                    trace("Could not parse the XML file.");                }        }        private function xmlloader_ioError(e:IOErrorEvent):void {            trace("Had problem loading the XML File.");        }
