Can I load xml file from a url on an iphone app?

You can use the IOErrorEvent.IO_ERROR listener and trace for debugging to see if your xml is being received.

example...

var pageData:XML;

private function getInfo():void {

var url:String = "urlTo.xml";

var myXMLLoader:URLLoader = new URLLoader();

myXMLLoader.addEventListener(Event.COMPLETE, onLoaded, false, 0, true);

myXMLLoader.addEventListener(IOErrorEvent.IO_ERROR, errorXML, false, 0, true);

myXMLLoader.load(new URLRequest(url));

}

private function onLoaded(e:Event):void {

pageData = new XML(e.target.data);

pageData.ignoreWhitespace = true;

//for testing in Flash

trace("Data received: "+pageData);

//for testing to device

// example: textfieldOnStage.htmlText = pageData;

}

//handle xml load error

private function errorXML(e:Event):void {

trace("XML Error:"+ e);

// example: textfieldOnStage.htmlText = pageData;

}
