我在 flex 中做了一个小项目。用户可以查找书评。当输入书名时，我会返回所有评论，而不是该特定书的评论。
我的代码：
<?xml version="1.0" encoding="utf-8"?>

import mx.rpc.events.ResultEvent;
public function handleMenu(event:ResultEvent):void{
DescrBooks.dataProvider = event.result.menu.menuitem;
}
public function Start():void{
//favorieten.addEventListener(ResultEvent.RESULT,handleMenu);
favorieten.send();
}
public function ShowBooks(SelectedBooks:Object):String{
var descr:String = SelectedBooks.itemDesc;
var D:String = descr
return D;
}

echo $xml_output;?>
表 RMA_Reviews 如下所示：（无法发布屏幕截图，因为我没有足够的代表）

所以我的问题是：我怎样才能只显示你在文本字段中输入的书籍的值。
