AS3 simple save function in flash for desktop application xml

Question

I'm making a basic drag and drop application in flash. I would like all that is in the current flash screen to be saved into an XML file. (or any other straight forward solution) How should I go about this?

I want a simple save function on a mouse click so that when you click 'Save', all of the current arrangement is saved somewhere and ready to be reloaded when the player clicks 'restore'.

Thanks all. (P.S i'm a designer and novice to AS3, I studied AS2)

stop();

Mouse.hide();
stage.addEventListener(MouseEvent.MOUSE_MOVE,follow);
function follow(evt:MouseEvent){
    tweezer_cur.x = mouseX;
    tweezer_cur.y = mouseY;
}

//Resetter btn ---------------------

reset_btn.addEventListener(MouseEvent.CLICK, startover);

function startover(event:MouseEvent):void
 {
 gotoAndPlay(1);
 }

//------------------------------ fullscreen
function setFullScreen():void {
if (stage.displayState== "normal") {
stage.displayState="fullScreen";
stage.scaleMode = StageScaleMode.NO_SCALE;
} else {
stage.displayState="normal";
}
}

fullbtn.addEventListener(MouseEvent.CLICK, goFull); 
    // btn declared - - - - - - - - 

    function goFull(event:MouseEvent):void {
 setFullScreen();
 };

 //---------------------------- print project



printme_btn.addEventListener(MouseEvent.CLICK, startPrintJobHandler, false, 0, true);

    function startPrintJobHandler(event:MouseEvent):void
    {
     var printJob:PrintJob = new PrintJob();
     printJob.start()

     var printJobOptions:PrintJobOptions = new PrintJobOptions(); 
     printJobOptions.printAsBitmap = true; 

     printJob.addPage(artworkContainer, null, printJobOptions);

     printJob.send();
 }

 //--- all the draggables will live here
dragme.addEventListener(MouseEvent.MOUSE_DOWN, pickupObject);
dragme.addEventListener(MouseEvent.MOUSE_UP, dropObject);

function pickupObject(event:MouseEvent):void {
event.target.startDrag(true);
}
 function dropObject(event:MouseEvent):void {
 event.target.stopDrag();
}
