flex读取xml数据并呈现在DataGrid中

新建一个flex工程，工程名为user，user.mxml 如下

<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute" creationComplete="srv.send()">
<mx:Script>
	<![CDATA[
		import mx.collections.XMLListCollection;
		import mx.rpc.events.ResultEvent;

    	[Bindable]
        private var users:XML;

		private  function resultUsers(event:ResultEvent):void{//处理结果
			users = XML(event.result);
			datagrid.dataProvider=users.children();//XMLList
         }
	]]>
</mx:Script>
<mx:HTTPService url="user.xml" useProxy="false" id="srv" resultFormat="xml" result="resultUsers(event)">
</mx:HTTPService>
<mx:DataGrid width="400" height="200" id="datagrid">
		<mx:columns>
			<mx:DataGridColumn headerText="ID" dataField="ID"/>
			<mx:DataGridColumn headerText="姓名" dataField="name"/>
			<mx:DataGridColumn headerText="年龄" dataField="age"/>
		</mx:columns>
	</mx:DataGrid>
</mx:Application>

在同一目录下简历如下xml文件，user.xml

<?xml version="1.0" encoding="utf-8"?>
<users>
    <user>
       <ID>213001</ID>
       <name>飞机</name>
       <age>22</age>
   </user>
   <user>
       <ID>213003</ID>
       <name>痞子</name>
       <age>23</age>
   </user>
   <user>
       <ID>213006</ID>
       <name>嗨嗨</name>

   </user>
   <user>
