how to read particular xml value using flex?

Question

I used HTTPService for reading xml, but I want only a particular xml field value like the first node id.

The HTTPService object is:

<mx:HTTPService result="getid(event)" id="xml_coupon" url="###" useProxy="false" resultFormat="e4x"/>

The getid(event) function is:

public function getid(evt:ResultEvent):void
{
    var id:number=evt.result.id;
    Alert.show(id.tostring);
}

The getid function shows all ids, but I want the first index id only. How can I read this? I tried Alert.show(evt.getChildAt(1).id); but it shows an error. If you know, please help me.

hey do some thing like this

if xml is like this

<mx:XML id="usersXML">
  <root>
    <users>
      <user id="1" lovesDonuts="Yes">
        <firstname>Tariq</firstname>
        <lastname>Ahmed</lastname>
      </user>
      <user id="2" lovesDonuts="Yes">
        <firstname>Jon</firstname>
        <lastname>Hirschi</lastname>
      </user>
    </users>
  </root>

usersXML.users.user[1].@id

This is the right idea, but so there is no confusion, you are returning "Jon" and "2", not "Tariq" and "1". The first user is the [0] index.
