我一直在绞尽脑汁试图从 xml 中提取 cdata，但没有成功。这是我的代码。

<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml"
      xmlns:s="library://ns.adobe.com/flex/spark" 
     creationComplete="myData.send();" backgroundColor="white" >

<mx:HTTPService id="myData" resultFormat="e4x" url="./assets/rawXML.xml" result="handleResult1(event)"/>
<mx:Script><![CDATA[
    import mx.collections.XMLListCollection;
    import mx.rpc.events.*;
    [Bindable]
    private var firstName:String;
    [Bindable]
    private var myXML:XMLList;

    private function handleResult1(event:ResultEvent):void{
        myXML = event.result.ROW;
        for each(var siteXML:XML in myXML){
            firstName = siteXML..SC_DF_FIELD_3.text();
        }
    }
]]>
</mx:Script>        
<mx:TextArea text = "{firstName}" height="200" width="800"/>
</mx:Application>

这是我的 XML；

关于如何让 SC_DF_FIELD_3 字段增加的任何建议？无论我尝试什么，我都只会出现姓氏（Woodsman，Kevin）。我很确定它会覆盖 for each 循环中的 firstname 变量，但我不确定如何更改它。任何帮助将不胜感激！

假设您想要显示TextArea组件中的所有名称，并假设您的代码有效。

如果你想显示这个：

ulo
Joseph
Woodsman
Kevin

也许这会很有用：

<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml"

      xmlns:s="library://ns.adobe.com/flex/spark" 
     creationComplete="myData.send();" backgroundColor="white" >

<mx:HTTPService id="myData" resultFormat="e4x" url="./assets/rawXML.xml" result="handleResult1(event)"/>
<mx:Script><![CDATA[


    import mx.collections.XMLListCollection;
    import mx.rpc.events.*;

    private var names:String;
    [Bindable]
    private var myXML:XMLList;

    private function handleResult1(event:ResultEvent):void{
        myXML = event.result.ROW;
        names= "";

        for each(var siteXML:XML in myXML){
            names= names + '-' + siteXML..SC_DF_FIELD_3.text();
        }
        txtArea.text = names;
    }
]]>
</mx:Script>        

<mx:TextArea id="txtArea" height="200" width="800" />
</mx:Application>

试一试，告诉我它有效。
