Flex读取XML文件主要通过以下两种方式：

(1) 通过HTTPService
(2) 通过URLLoader
代码如下：

<?xml version="1.0" encoding="utf-8"?><mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute" creationComplete="init()"><mx:Script>   <![CDATA[    import mx.collections.ArrayCollection;    import mx.rpc.events.ResultEvent;    import mx.rpc.http.HTTPService;    public const xmlUrl:String = "config.xml";    [Bindable] private var colors1:ArrayCollection;    [Bindable] private var colors2:XML;     private function init():void{     //方法一：通过HTTPService     var service:HTTPService = new HTTPService();     service.url = xmlUrl;     service.addEventListener(ResultEvent.RESULT, resultHandler);     service.send();        //方法二：通过URLLoader     var request:URLRequest = new URLRequest(xmlUrl);     var loader:URLLoader = new URLLoader(request);     loader.addEventListener(Event.COMPLETE, loaderCompleteHandler);    }    private function resultHandler(event:ResultEvent):void{     colors1 = event.result.colors.color;    }    private function loaderCompleteHandler(event:Event):void{     colors2 = new XML(event.target.data);    }   ]]></mx:Script><mx:List x="100" y="150" dataProvider="{colors1}" labelField="name"></mx:List><mx:List x="300" y="150" dataProvider="{colors2.color}" labelField="@name"></mx:List></mx:Application>
