Question

Can anyone see whats wrong with either the code to grab the XML or the XML file itself? It looks well formed to me and I don’t see the cause of the error:

A TypeError has occured:
TypeError: Error #1088: The markup in the document following the root element must be well-formed.

    var file:String = 'config.xml';
    var loader:URLLoader = new URLLoader();
    var request:URLRequest = new URLRequest(file);
    loader.load(request);
    loader.addEventListener("complete", onComplete);
    loader.addEventListener("ioError", onIOError);

    private function onIOError(event:Event):void 
    {
        trace("IOERROR (maybe XML file does not exit or have an incorrect name)");
    }

    private function onComplete(event:Event):void 
    {
        var loader:URLLoader = event.target as URLLoader;
        if (loader != null) {
            try {
                var settings:XML = new XML(loader.data);
            } catch (e:TypeError) {
                trace("A TypeError has occured: \r\t" + e);
            }

        } else {
            trace("Loader is not a URLLoader!");
        }
    }

config.xml

<?xml version="1.0" encoding="UTF-8"?>
<settings>
    <setting1>1</setting1>
    <showDebug>2</showDebug>
    <someOtherSetting>3</someOtherSetting>
</settings>

What did you create the XML document in?

I had something similar occur the other day, depending on the text/xml editor it may add a Byte Order Mark to the beginning Wikipedia BOM . This instantly invalidates the XML file. Try copying and pasting what you have into notepad and re-saving it.

Or, if you have a Linux machine available, the BOM will appear in VI as ” and you can remove it.

Also, just for reference, the utf encoding for the BOM is ‘\ufeff’
