关于Flex修改XML文件的问题，急！！！

如何使用Flex修改xml的指定节点
repeater如下
<mx:XML id="imageXML" source="assets/image.xml" />
<mx:Repeater id="rep" dataProvider="{imageXML.image}">
<mx:Tile paddingLeft="20" paddingTop="12" paddingRight="12" paddingBottom="12">
<mx:Image source="{rep.currentItem.@src}" width="130" height="177" />
<mx:VBox>
<mx:Label text="{rep.currentItem.@name}" fontSize="12" />
<mx:Label text="{rep.currentItem.@number}" fontSize="12" />
<mx:Label text="{rep.currentItem.@clazz}" fontSize="12" />
<mx:Label text="共计得{rep.currentItem.@counts}票" fontSize="12"/>
<mx:Button label="投他一票" click="vote(event)" fontSize="12" />
</mx:VBox>
</mx:Tile>
</mx:Repeater>
外部XML文件为
<images>
<image src="assets/29051242785099776.jpg" alt="Button" name="张三" number="200936263" clazz="11040801" counts="22" />
</images>
要求点击一下Button后xml对应节点的counts属性增加1vote函数怎么写？？？

Answer 1

var _xml:XML=你的xml;

function vote(e:Event):void
{
var n:Number = Number(_xml.image[0].@counts);
_xml.image[0].@counts = n+1;
}
