Getting (xml) data into a swf file

hi,

I am now trying to read in parameters from my html file into my as3 file.

The original code that I am reading in from used the same file name for the XML each time-I would rather add a date-stamp to the end of the XML file and then more than one person can use the app at the same time :-)

So what I want to do is to read in a parameter name and value and then add this to the file name already in my as3 file and use that.

I know its dead simple but having read around about inputting parameters and retrieving them, I'm struggling.

original code------------------------------------------------------------------------------------

import fl.containers.ScrollPane;import fl.containers.ScrollPane;

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

var cell_spacing:Number = 0.4425;

var strXML:String = "seq_list.xml";

xmlLoader.addEventListener(Event.COMPLETE, LoadXML); 
xmlLoader.load(new URLRequest(strXML + "?" + Math.random())); //

var sp:ScrollPane = new ScrollPane();
this.addChild(sp);

var mcHolder:MovieClip = new mc_holder();

....more code.....

my alterations in bold---------------------------------------------------------------------

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

var cell_spacing:Number = 0.4425;

var myXmlId:String;

this.loaderInfo.addEventListener(Event.COMPLETE, xmlLoaderComplete);

var strXML:String = "seq_list_"+myXmlId+".xml";

xmlLoader.addEventListener(Event.COMPLETE, LoadXML);
 
xmlLoader.load(new URLRequest(strXML + "?" + Math.random())); //

var sp:ScrollPane = new ScrollPane();
this.addChild(sp);

var mcHolder:MovieClip = new mc_holder();

function xmlLoaderComplete(myEvent:Event):void
{
  var myQueryStrings=this.loaderInfo.parameters;
  myXmlId=myQueryStrings.xmlId;
}

....more code.....

The result that I am getting is that my application is looking for a file named "seq_list_null.xml" so presumably I'm not setting myXmlId correctly.

I'm sending it from the html file like:

<param name="movie" value="/seq_list.swf?xmlId=2" />

I presume this line is ok and the problem is coming in with the loading in the as3 file.

Can anyone point out what is wrong?

Thanks,

Sandy
