XML an AS3 'addItem(s)"

I was following a tutorial on the Adobe developer network that is a video playlist being populated by an XML file. I’m new to using XML and I’m kind of stumped and I was hoping someone would help me. I would like to add another element or attribute to the XML file but how do I call it in the Action Script?

AS3>>>There is a class constructor and a method which loads the XML data which in turn loads another method (‘initMediaPlayer’) below which is what is going through the XML nodes :


public function initMediaPlayer(event:Event):void {
    var myXML:XML = new XML(xmlLoader.data);
    var item:XML;
    for each (item in myXML.vid) {
// populate playlist.
// Get thumbnail value and assign to cellrenderer.
    var thumbnail:String;
    if (item.hasOwnProperty("@thumbnail")>0) {
        thumbnail = item.@thumbnail;
        }
// Send data to tileList.
    tileList.addItem({label:item.attribute("description").toXMLString(), 
        data:item.attribute("src").toXMLString(),
        source:thumbnail});
    }

XML file looks like this:


<?xml version="1.0" encoding="UTF-8"?>
<playlist id="My Video Player" >
    
    <vid description="Lorem ipsum dolor sit amet" 
        src="movies/myMovie.flv" 
        thumbnail="thumbnails/smallPic.jpg" />
    
</playlist>

So now I would like to add another element


<?xml version="1.0" encoding="UTF-8"?>
<playlist id="My Video Player" >
    
    <vid description="Lorem ipsum dolor sit amet" 
        **details="consectetuer adipiscing elit. Maecenas quis nunc"**
        src="movies/myMovie.flv" 
        thumbnail="thumbnails/smallPic.jpg" />
        
</playlist>

How do I modify the method to get another element …or does anyone know of a tutorial out there. Thanks.
