Question

Okay getting some weirdness. I have a simple URLLoader in AS3 that loads an external XML document. It’s loading just fine, I get a correct 302 Not Modified response in Charles, however flash tells me:

“URL Not Found”

Here is the relevant code:

        //=============================================================================================
    public function openXML(name:String):void { //decides what XML data feed and opens it
    //=============================================================================================


                var xmlLoader:URLLoader = new URLLoader();
        var xmlData:XML = new XML();

        //add event listener to URLLoader to call closeXML upon completion
        xmlLoader.addEventListener(Event.COMPLETE, closeXML);

        xmlLoader.load(new URLRequest("http://www.gessnerengineering.com/projects"));

        //=========================================================
        function closeXML(e:Event):void {
        //=========================================================
            xmlData = new XML(xmlLoader.data);
            xmlLoader.removeEventListener(Event.COMPLETE, closeXML);

            drawPage(name, xmlData);
        }

    }

The problem line according to the debugger is at:

    xmlLoader.load(new URLRequest("http://www.gessnerengineering.com/projects"));

I’ve verified that I can browse to the URL via my browser and cURL, and Charles says that my SWF can and IS successfully accessing it too. However I still get this URL Not Found error. According to the Flash Actionscript 3 documentation, this is the absolute correct way to use URLLoader to load external data including XML.

Updated code with pastie.

I’m finding your code’s structure a little odd – why do you have functions inside of a function?

I rewrote your code like this and it works perfectly fine (i just ran it on the timeline in flash cause i’m too lazy to set up a new project):

var xmlLoader:URLLoader = new URLLoader();
var xmlData:XML = new XML();
var request:URLRequest = new URLRequest("http://www.gessnerengineering.com/projects");
request.method = URLRequestMethod.GET;



//=============================================================================================
    function openXML(name:String):void { //decides what XML data feed and opens it
    //=============================================================================================



    //add event listener to URLLoader to call closeXML upon completion
    xmlLoader.addEventListener(Event.COMPLETE, closeXML);
    xmlLoader.addEventListener(IOErrorEvent.IO_ERROR, onIOError);
    xmlLoader.addEventListener(SecurityErrorEvent.SECURITY_ERROR, securityError);
    xmlLoader.load(new URLRequest("http://www.gessnerengineering.com/projects"));

}
function onIOError(e:IOErrorEvent):void {  
    trace("Error loading URL.");  
} 

function securityError(e:SecurityErrorEvent):void {
    trace("security error");
}


function closeXML(e:Event):void {
    trace('xmlLoader.data ' + xmlLoader.data);
    xmlData = new XML(xmlLoader.data);
    xmlLoader.removeEventListener(Event.COMPLETE, closeXML);
}



openXML('ljkl');
