Question

I have created an aspx page which dynamicaly creates an xml string and posts it back to the client.

        protected void Page_Load(object sender, EventArgs e)
    {
        Response.Clear();
        Response.ContentType = "text/xml";
        Response.ContentEncoding = Encoding.UTF8;

        var flashAssets = Asset.GetScrollingFlashAssets();

        var xmlResponse = new StringBuilder(@"<?xml version=""1.0"" encoding=""UTF-8"" ?><assets>");
        flashAssets.ForEach(asset => xmlResponse.Append(@"<asset>handlers/ImageHandler.ashx?liAssetID=" + asset.AssetID + "</asset>"));
        xmlResponse.Append("</assets>");
        Response.Write(xmlResponse.ToString());
    }

It creates valid XML and when I save this code to a static .xml file the flash can read it fine, though when it tried to read it from the ASPX it fails with “1090 XML parser failure: element is malformed”.

I do not have http compression on.

Flash code.

//---------loading the external xml file-------
var urlRequest:URLRequest = new URLRequest("../xml/CaseStudyFlashAssets.aspx");
var urlLoader:URLLoader = new URLLoader();
var myXML:XML = new XML();
var xmlList:XMLList;
myXML.ignoreWhitespace = true;
urlLoader.addEventListener(Event.COMPLETE,fileLoaded);
urlLoader.load(urlRequest);

Any ideas?

It sounds like when flash calls the aspx page it gets a different response than you’re expecting, try using this fileLoaded function:

public function fileLoaded(event:Event):void{
     trace('urlLoader.data is ' + urlLoader.data);
     try{
          var xmlData:XML = XML(urlLoader.data);
     } catch (e:Error) {
          trace('Error creating XML: ' + e);
     }
}

which should hopefully give you some more info about whats going wrong.
