即时消息灵活开发并需要帮助。Flex更新XML

我有一个xml文件,其中包含我想要更新的数据,如果用户更改了任何内容,则该文件将保存在其本地程序文件的应用程序所在的位置。

这里是我的代码读取XML文件:

<fx:Declarations> 
    <s:HTTPService id="systemData" url="data/system.xml" method="POST"/> 
</fx:Declarations> 

<fx:Script> 
    <![CDATA[ 
     import mx.collections.ArrayCollection; 
     import mx.rpc.events.ResultEvent; 

     [Bindable] 
     private var systemInfo:Object = new Object(); 

     private var interval:uint; 

     [Bindable] 
     private var xmlData:ArrayCollection = new ArrayCollection(); 

     private function viewMain(event:Event):void 
     { 

      mainWindow.visible = true; 
      systemWindow.visible = false; 
     } 

     private function viewSystem(event:Event):void 
     { 

      mainWindow.visible = false; 
      systemWindow.visible = true; 


     } 

     public function init():void 
     { 

      systemData.addEventListener(ResultEvent.RESULT, getXML); 
      systemData.send(); 

      interval = setInterval(reloadXML, 1800000); 

     } 

     private function getXML(e:ResultEvent):void 
     { 

      systemInfo = systemData.lastResult.system; 
      systemIP.text = systemInfo.systemip; 
      systemPort.text = systemInfo.systemport; 
      systemUsername.text = systemInfo.systemusername; 
      systemPassword.text = systemInfo.systempassword; 

     } 
     private function reloadXML():void 
     { 
      systemData.send(); 
     } 


    ]]> 
</fx:Script> 


<s:BorderContainer id="mainWindow" width="100%" height="100%" visible="false"> 
    <s:Button x="434" y="102" label="System Settings" click="viewSystem(event)"/> 
    <s:Button x="468" y="147" label="Button" /> 

</s:BorderContainer> 


<s:BorderContainer id="systemWindow" width="100%" height="100%" visible="true"> 
    <s:Panel width="800" height="600" horizontalCenter="0" title="System Settings" 
      verticalCenter="0"> 
     <s:Label x="33" y="41" text="Server IP:"/> 
     <s:Label x="33" y="66" text="Port:"/> 
     <s:Label x="33" y="90" text="Username:"/> 
     <s:Label x="33" y="115" text="Password:"/> 
     <s:TextInput x="182" y="31" width="250" id="systemIP"/> 
     <s:TextInput x="182" y="56" width="250" id="systemPort"/> 
     <s:TextInput x="182" y="80" width="250" id="systemUsername"/> 
     <s:TextInput x="182" y="105" width="250" id="systemPassword"/> 
     <s:Button x="345" y="135" label="Save to XML" /> 
     <s:Button x="718" y="-26" label="Main" click="viewMain(event)"/> 
    </s:Panel> 
</s:BorderContainer> 

的XML文件:

 <?xml version="1.0" encoding="utf-8" standalone="no"?> 
    <system> 
    <systemip>127.0.0.0</systemip> 
    <systemport>80</systemport> 
    <systemusername>rootu</systemusername> 
    <systempassword>passu</systempassword> 
    </system> 

在此先感谢
