Question

I’m coding a website in pure AS3 using FlashDevelop and have an object that loads an XML file on init. Is there a good way to make my main function wait until it has finished loading? I know about onComplete events and how to use them internally in the object but I’m not sure how to proceed.

Thanks in advance!

package
{
import flash.display.Sprite;
import flash.net.URLLoader;
import flash.net.URLRequest;
import flash.events.Event;
import flash.events.IOErrorEvent;

public class HandleXMLData extends Sprite
    {
    private var xmlData:XML;
    private var XMLFileURL:String = "myXML.xml";

    public function HandleXMLData()
        {
        var xmlLoader:URLLoader = new URLLoader();
        xmlLoader.addEventListener(IOErrorEvent.IO_ERROR, errorHandler);
        xmlLoader.addEventListener(Event.COMPLETE, xmlDataHandler);
        xmlLoader.load(new URLRequest(XMLFileURL));
        }

    private function xmlDataHandler(evt:Event):void
        {
        evt.target.removeEventListener(IOErrorEvent.IO_ERROR, errorHandler);
        evt.target.removeEventListener(Event.COMPLETE, xmlDataHandler);
        xmlData = new XML(evt.target.data);

        init();
        }

    private function errorHandler(evt:IOErrorEvent):void
        {
        throw(evt.text);
        }

    private function init():void
        {
        //Initialization Routine
        }
    }
}
