[flexcoders] Newbie XML to ArrayCollection Confusion

[t_singe]

I'm hoping someone can help explain how to retrieve an XML doc via
webservice and then create an ArrayCollection from it.  Using the code
and xml below, I am able to retrieve the xml alright and access the
nodes, but when I attempt to convert the xml object to an array I end
up with a single element array.  

My xml document looks like:
  <?xml version="1.0" encoding="UTF-8" ?> 
- <scores>
     <score position="1">4</score> 
     <score position="2">1</score> 
     <score position="3">2</score> 
     <score position="4">3</score> 
     <score position="5">5</score> 
     <score position="6">0</score> 
     <score position="7">9</score> 
     <score position="8">6</score> 
     <score position="9">8</score> 
     <score position="10">7</score> 
  </scores>

My webservice event handler looks like:
public function hScoresHandler(event:ResultEvent):void {
   var xmlResult:XML ;
   var hScores = new ArrayCollection();   

   xmlResult = new XML(event.result);
   
   // This properly outputs the entire XML document
   trace(xmlResult);
   
   // These properly output the content from different nodes in the
   // XMLM document
   trace("first (0) position: " + xmlResult.score[0]);
   trace("five position: " + xmlResult.score[5]);
   trace("five position: " + [EMAIL PROTECTED]);
                                
   // Convert XML to Array
   hScores = ArrayUtil.toArray(xmlResult);

   // For some reason this outputs a null string
   trace(hScores);
   
   // Why is the length only one?
   trace("length: " + hScores.length);
}
