How to create and add an XML node at run time ?

Question

Hello and thanks to All of You i've been learning a lot since i use this forum..
I'm having another problem, !!! i would like that my executeShape function insert a new XMLChildnode called "adverts"  to my Pages:XML via the evenListener of the execute_bt. I tryed copying the nodes and it works but it copy a blank "adverts" node in betwen each node copied. so i tryed with appendChild, but it works only once, then it say error. so i tryed with inserChildafter or inserChildbefore but this one doesnt work at all because "advert" doesnt exist. I understand why all my suggestions does'nt work (copied or append or insertchild), but i dont figure out how to get what i want . i love AS but im no advance in enought..
My XML structure that I want is quite simple : i just want that every time I press the execute_bt, a new "adverts" is added to the Pages XML
<Pages>
  <page id="Page1">
    <adverts>
      <adfile>Null</adfile>
      <adwidth>1</adwidth>
      <adheight>50</adheight>
      <adposx>514</adposx>
      <adposy>200</adposy>
    </adverts>
   <adverts>
       <adfile>Null</adfile>
       <adwidth>1</adwidth>
       <adheight>50</adheight>
       <adposx>514</adposx>
       <adposy>200</adposy>
     </adverts>
  </page>
</Pages>
Here is the code of the clip:
execute_bt.addEventListener(MouseEvent.MOUSE_UP,executeShape);
var _adWidth:uint=uint(Adwidth.text);
var _adHeight:Number=Number(Adheight.text);
var _adFileName:String=String(adFileName.text);
var _adpage:String=String(PageInstanceName.text);
var _adPosx:Number;
var _adPosy:Number;
var _adArrayID:int;
var currentColor:Number;
var i:int=0;
var element:int=0;
var Pages:XML=<Pages />;
Pages.page = <page />;
Pages.page.@id=_adpage;
var boldText:TextFormat = new TextFormat();
with (boldText) {
    font="Verdana";
    size=10;
    color=0xFFFFFF;
    bold=false;
    multiline=true;
function executeShape(evt:MouseEvent):void {
    _adArrayID=i;
    currentColor=Adcolor.selectedColor;
    var Container:MovieClip= new MovieClip();
    Container.name=adFileName.text;
    Container.id=_adArrayID;
    var gr:Graphics=Container.graphics;
    gr.lineStyle();
    gr.beginFill(Adcolor.selectedColor, 2);
    gr.drawRect(0,0,(uint(Adwidth.text)*70),Number(Adheight.text)*1.68);
    gr.endFill();
    var Lbl:TextField = new TextField();
    Lbl.x=Lbl.y=1;
    Lbl.autoSize=TextFieldAutoSize.LEFT;
    Lbl.multiline=Lbl.wordWrap=true;
    Lbl.width=(uint(Adwidth.text)*65);
    Lbl.text=String(adFileName.text);
    Lbl.setTextFormat(boldText);
    var btn:Sprite=new CreateRoundRectButton(20,20,5,0,0xFFFFFF,"X",0xFF0000);
    btn.name="delete";
    btn.x=9;
    btn.y=50;
    addChild(Container);
    Container.x=514;
    Container.y=200;
    Container.addChild(Lbl);
    Container.addChild(btn);
    index.text=String(Container.id);
    file.text=String(Container.name);
    widht.text=String(uint(Adwidth.text));
    heigth.text=String(Number(Adheight.text));
    posx.text=String(Container.x);
    posy.text=String(Container.y);   
    Pages.page.appendChild(<adverts />);
   Pages.page.adverts.appendChild(<adfile />);
    Pages.page.adverts.appendChild(<adwidth />);
    Pages.page.adverts.appendChild(<adheight />);
    Pages.page.adverts.appendChild(<adposx />);
    Pages.page.adverts.appendChild(<adposy />);
    Pages.page.adverts.adfile=String(Container.name);
    Pages.page.adverts.adwidth=String(uint(Adwidth.text));
    Pages.page.adverts.adheight=String(Number(Adheight.text));
    Pages.page.adverts.adposx= String(Container.x);
    Pages.page.adverts.adposy=String(Container.y);
   //var templist:XMLList= Pages.page.adverts.copy();
    //templist[0].adfile = String(Container.name);
    //templist[0].adwidth = String(uint(Adwidth.text));
    //templist[0].adheight = String(Number(Adheight.text));
    //templist[0].adposx = String(Container.x);
    //templist[0].adposy = String(Container.y);

    trace(Pages);
    btn.addEventListener(MouseEvent.CLICK, deleteme, false, 0, true);
    Container.addEventListener(MouseEvent.MOUSE_DOWN,StartDrag);
    Container.addEventListener(MouseEvent.MOUSE_UP,StopDrag);

Sorry , i Found the solution......:
var Pages:XML=<Pages />;
Pages.page = <page />;
Pages.page.@id=_adpage;
var boldText:TextFormat = new TextFormat();
with (boldText) {
    font="Verdana";
    size=10;
    color=0xFFFFFF;
    bold=false;
    multiline=true;
function executeShape(evt:MouseEvent):void {
    _adArrayID=i;
    currentColor=Adcolor.selectedColor;
    var Container:MovieClip= new MovieClip();
    Container.name=adFileName.text;
    Container.id=_adArrayID;
    var gr:Graphics=Container.graphics;
    gr.lineStyle();
    gr.beginFill(Adcolor.selectedColor, 2);
    gr.drawRect(0,0,(uint(Adwidth.text)*70),Number(Adheight.text)*1.68);
    gr.endFill();
    var Lbl:TextField = new TextField();
    Lbl.x=Lbl.y=1;
    Lbl.autoSize=TextFieldAutoSize.LEFT;
    Lbl.multiline=Lbl.wordWrap=true;
    Lbl.width=(uint(Adwidth.text)*65);
    Lbl.text=String(adFileName.text);
    Lbl.setTextFormat(boldText);
    var btn:Sprite=new CreateRoundRectButton(20,20,5,0,0xFFFFFF,"X",0xFF0000);
    btn.name="delete";
    btn.x=9;
    btn.y=50;
    addChild(Container);
    Container.x=514;
    Container.y=200;
    Container.addChild(Lbl);
    Container.addChild(btn);
    index.text=String(Container.id);
    file.text=String(Container.name);
    widht.text=String(uint(Adwidth.text));
    heigth.text=String(Number(Adheight.text));
    posx.text=String(Container.x);
    posy.text=String(Container.y);   
    var adverts:XML= new XML;
    adverts=<adverts />;
    adverts.adfile=<adfile />;
    adverts.adwidth=<adwidth />;
    adverts.adheight=<adheight />;
    adverts.adposx=<adposx />;
    adverts.adposy=<adposy />;
    adverts.adfile=String(Container.name);
    adverts.adwidth=String(uint(Adwidth.text));
    adverts.adheight=String(Number(Adheight.text));
    adverts.adposx= String(Container.x);
    adverts.adposy=String(Container.y);
    Pages.page.appendChild(adverts);
    trace(adverts);
    btn.addEventListener(MouseEvent.CLICK, deleteme, false, 0, true);
    Container.addEventListener(MouseEvent.MOUSE_DOWN,StartDrag);
    Container.addEventListener(MouseEvent.MOUSE_UP,StopDrag);
    i++;
