Hi all, I would like to ask …
How to retrieve the exact XML data in AS3 ??

here is the XML set

 
<xml>
 <group>
  <id>1</id>
  <item>Item A</item>
 </group>
 <group>
  <id>2</id>
  <item>Item B</item>
 </group>
</xml>


 
var vReq:URLRequest = new URLRequest("theList.xml");
var ldr:URLLoader = new URLLoader(vReq);
ldr.addEventListener(Event.COMPLETE, onXMLLoaded);
function onXMLLoaded(e:Event):void {
 var xDoc:XMLDocument = new XMLDocument();
 xDoc.ignoreWhite = true;
 var vTrack:XML = new XML(ldr.data);
 xDoc.parseXML(vTrack.toXMLString());
 var vTotalTrack:Number = xDoc.firstChild.childNodes.length;
 for (var i=0; i < vTotalTrack; i++) {
  trace(xDoc.firstChild.childNodes*.childNodes[0]);
  trace(xDoc.firstChild.childNodes*.childNodes[1]);
 }
}

the output is :
<id>1</id>
<item>item A</otem>
<id>2</td>
<item>item B</item>

I have tried the
xDoc.firstChild.childNodes*.childNodes[0].value
xDoc.firstChild.childNodes*.childNodes[0].data
but it doesn’t work …

i just want the output :
1
item A
2
item B

anybody could help ??
Thanks
