flex HTTPService读取XML并解析

读取如下的xml文件，并解析（ue.xml）

<?xml version="1.0" encoding="UTF-8"?>
<root>
	<nodes>
		<node id="1">a</node>
		<node id="2">b</node>
		<node id="3">c</node>
		<node id="4">d</node>
		<node id="5">e</node>
		<node id="6">f</node>
	</nodes>
</root>

flex的编写如下（使用的是flex4版本，flex3基本类似）

<?xml version="1.0" encoding="utf-8"?>
<s:Application xmlns:fx="http://ns.adobe.com/mxml/2009"
			   xmlns:s="library://ns.adobe.com/flex/spark"
			   xmlns:mx="library://ns.adobe.com/flex/mx" minWidth="955" minHeight="600" creationComplete="init()">

	<fx:Script>
		<![CDATA[
			import mx.controls.Alert;
			import mx.events.FlexEvent;
			import mx.rpc.events.ResultEvent;

			protected function init():void
			{
				dataXml.send();
			}

			protected function dataXml_resultHandler(event:ResultEvent):void
			{
				var data:XML = XML(event.result);
				for each(var nodeXML:XML in data.nodes.node){
					trace(nodeXML.@id+"\t"+nodeXML);
					Alert.show(nodeXML.@id+"\t"+nodeXML);
				}
			}

		]]>
	</fx:Script>
	<fx:Declarations>
		<!-- 将非可视元素（例如服务、值对象）放在此处 -->
		<s:HTTPService id="dataXml" url="../ue.xml" resultFormat="xml" result="dataXml_resultHandler(event)" />
	</fx:Declarations>
</s:Application>
