Convert a Xml to an ArrayCollection in AS3

Here is a quick method to convert a xml to an array collection. Because you pass the XML url (Eg: './assets/data.xml') to the first argument you will receive the array asynchronous using the callback function. If you have already the xml content in a variable use only the code in the anonymous function at the event.COMPLETE dispatch.

static public function convertXmlToArrayCollection( xmlUrl:String, rootTag:String, repeatedElement:String, callback:Function ):void
{
	var xmlLoader:URLLoader = new URLLoader();
	xmlLoader.addEventListener(Event.COMPLETE, function(e:Event):void
	{
		var xml:XMLDocument = new XMLDocument( e.target.data );
		xml.ignoreWhite = true;

		var decoder:SimpleXMLDecoder = new SimpleXMLDecoder();
		var data:Object = decoder.decodeXML( xml );
		var array:Array= ArrayUtil.toArray(data[rootTag][repeatedElement]);

		callback(new ArrayCollection( array ));
	});
		xmlLoader.load(new URLRequest(xmlUrl));
}
