XML Menu Help - Delaying modules?

Hi there, I'm really new to actionscript, but I've managed to put together a flash xml menu. What I know want to do is delay the loading of each item so that the menu loads in a nice 1 at a time fashion. Can anyone help me with this? I'm pretty desperate!

This is the menu as it is:

MovieClip.prototype.Increment = function(maxAlpha, speed) {
this.onEnterFrame = function() {
this._alpha += speed;
if (this._alpha>=maxAlpha) {
this._alpha = maxAlpha;
delete this.onEnterFrame;
}
};
};
GenerateMenu = function(container, name, x, y, depth, node_xml) {
 var curr_node;
 var curr_item;
 var curr_menu = container.createEmptyMovieClip(name, depth);
 for (var i=0; i<node_xml.childNodes.length; i++) {
  curr_item = curr_menu.attachMovie("menuitem","item"+i+"_mc", i);
  
  curr_item._y = y + i*curr_item._height;
  curr_item._x = x;
  curr_item.trackAsMenu = true;
  
     with (curr_item) {
         _alpha = 0;
          Increment(2000, 20);
       } 
  
 

  
  
  
  
  

  curr_node = node_xml.childNodes[i];
  curr_item.action = curr_node.attributes.action;
  curr_item.variables = curr_node.attributes.variables;
  curr_item.name.text = curr_node.attributes.name;
  
  if (node_xml.childNodes[i].nodeName == "menu"){
   curr_item.node_xml = curr_node;
   curr_item.onRollOver = curr_item.onDragOver = function(){
    var x = this._x + this._width + 3;
    var y = this._y + 0;
    GenerateMenu(curr_menu, "submenu_mc", x, y, 1000000, this.node_xml);
    
    var col = new Color(this.background);
    col.setRGB(000000);
    
   };
  }else{ 
   curr_item.arrow._visible = false;
   
   curr_item.onRollOver = curr_item.onDragOver = function(){
    curr_menu.submenu_mc.removeMovieClip();
    
    var col = new Color(this.background);
    col.setRGB(000000);
    
    
    
   };
  }
  
  curr_item.onRollOut = curr_item.onDragOut = function(){
   
   var col = new Color(this.background);
   col.setTransform({ra:100,rb:0,ga:100,gb:0,ba:100,bb:0});
  };
  
  curr_item.onRelease = function(){
   Actions[this.action](this.variables);
   CloseSubmenus();
  };
 } 
};
   
CreateMainMenu = function(x, y, depth, menu_xml){
 
 GenerateMenu(this, "mainmenu_mc", x, y, depth, menu_xml.firstChild);
 
 mainmenu_mc.onMouseUp = function(){
  if (mainmenu_mc.submenu_mc && !mainmenu_mc.hitTest(_root._xmouse, _root._ymouse, true)){
   CloseSubmenus();
  }
 };
};
CloseSubmenus = function(){
 mainmenu_mc.submenu_mc.removeMovieClip();
};
Actions = Object();
Actions.loadMov = function(loadVar){
 loadMovie(loadVar, "Loader");
 menu_xml.load("menu3.xml");
};
Actions.unloadMov = function(urlVar){
 unloadMovie("Loader");
};
Actions.message = function(msg){
 message_txt.text = msg;
};
Actions.newMenu = function(menuxml){
 menu_xml.load(menuxml);
};
menu_xml = new XML();
menu_xml.ignoreWhite = true;
menu_xml.onLoad = function(ok){
 
 if (ok){
  CreateMainMenu(10, 10, 1, this);
  
 }else{
  
 }
};
menu_xml.load("menu1.xml");

Am I right in thinking I need to create a setinterval function perhaps where the loop begins? If so how would I implement.

Any thoughts and solutions on this problem will be greatly appreciated!

Many thanks
