btn.addEventListener(MouseEvent.CLICK,loadTxt);
function loadTxt(evt:MouseEvent):void
{
var urlLoader:URLLoader=new URLLoader();
urlLoader.load(new URLRequest("data.xml"));
urlLoader.addEventListener(Event.COMPLETE,finish);
}
function finish(evt:Event):void
{
var mydatas:XML=XML((evt.currentTarget as URLLoader).data);
mytxt.text=mydatas.c1.toString()+","+mydatas.c2.toString();
}
xml文件内容：
<?xml version="1.0" encoding="utf-8"?>
<cities>
<c1>北京</c1>
<c2>上海</c2>
</cities>
上述代码结果：
北京,上海
