主要有两个方法：

（1）通过HTTPService

（2）通过URLLoader

代码如下：

mxml代码

<?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>


config.xml文件

<colors>
<color name="LightGrey" value="#D3D3D3"/>
<color name="Silver" value="#C0C0C0"/>
<color name="DarkGray" value="#A9A9A9"/>
<color name="Gray" value="#808080"/>
