I've got some content related to my issue from net but still it won't solve my problem

private function init():void {

                                        var ldr:Loader = new Loader();

                                        ldr.contentLoaderInfo.addEventListener(Event.COMP LETE, imgLoaded);

  var s:String = "my/jpgPath/myjpgName.jpg";

                                        ldr.load(new URLRequest(s));

                              }

                              private function imgLoaded(e:Event):void{

                                        var info:LoaderInfo = e.target as LoaderInfo;

                                        var xmpXML:XML = getXMP(info.bytes);

  //trace(xmpXML);

                                        var meta:XMPMeta = new XMPMeta(xmpXML);

  //var packet:XML = meta.serializeToXML();

                                        var photoshop:Namespace = XMPConst.photoshop

                                        trace(meta.photoshop::AuthorsPosition);

                              }

                              private function trim(s:String):String{

  return s.replace( /^([\s|\t|\n]+)?(.*)([\s|\t|\n]+)?$/gm, "$2" );

                              }

                              private function getXMP(ba:ByteArray):XML{

                                        var LP:ByteArray = new ByteArray();

                                        var PACKET:ByteArray = new ByteArray();

                                        var l:int;

                                        ba.readBytes(LP, 2, 2);

                                        /*

                                        http://www.adobe.com/devnet/xmp.html

                                        read part 3: Storage in Files.

                                        that will explain the -2 -29 and other things you see here.

                                        */

                                        l = LP.readInt() - 2 -29;

                                        ba.readBytes(PACKET, 33, l);

                                        var p:String = trim(encode(PACKET) as String);

  var i:int = p.search('<x:xmpmeta xmlns:x="adobe:ns:meta/"');

  /* Delete all in front of the XMP XML */

                                        p = p.substr(i);

                                        /*

                                        For some reason this left some rubbish in front, so I'll hardcode it out for now

                                        TODO clean up

                                        */

                                        var ar:Array = p.split('<');

                                        var s:String = "";

                                        var q:int;

                                        var j:int = ar.length;

                                        for(q=1;q<j;q++){

                                                  s += '<'+ar[q];

                                        }

                                        i = s.search('</x:xmpmeta>');

                                        i += ('</x:xmpmeta>').length;

                                        s = s.slice(0,i);

  /* Delete all behind the XMP XML */

                                        return XML(s);

                              }

                              private static function encode(ba:ByteArray):String {

  var origPos:uint = ba.position;

  var result:Array = new Array();

   for (ba.position = 0; ba.position < ba.length - 1; )

   result.push(ba.readShort());

  if (ba.position != ba.length)

   result.push(ba.readByte() << 8);

  ba.position = origPos;

                                                  return String.fromCharCode.apply(null, result);

                              }

It seems there is a bug in XMPMeta class where it always throws an exception "The XMPMeta object cannot have qualifiers", Even created with default (no param).

Does anyone have any clue on this? please help

Thanks
