XML Menu Question

I’ve got a dynamically generated XML Menu. Works pretty well except for a couple of slight problems.

  1. I need the ‘menu’ node also be clickable to goto a URL
  2. If the ‘menu’ only has a single child node, I don’t want the child node to display.

Code is below. If anyone can help, that would be appreciated.



// generates a list of menu items (effectively one menu)
// given the inputted parameters.  This makes the main menu
// as well as any of the submenus
GenerateMenu = function(container, name, x, y, depth, node_xml,direction) {
    // variable declarations
    var curr_node;
    var curr_item;
    var curr_menu = container.createEmptyMovieClip(name, depth);
    
    // for all items or XML nodes (items and menus)
    // within this node_xml passed for this menu
    for (var i=0; i<node_xml.childNodes.length; i++) {
        // movieclip for each menu item
        if( direction == "horizontal"){
            curr_item = curr_menu.attachMovie("menuitem","item"+i+"_mc", i);
            curr_item._x = x + i*curr_item._width;
            curr_item._y = y;
        }
        //Assumre direction is vertical
        else{
            curr_item = curr_menu.attachMovie("submenuitem","item"+i+"_mc", i);
            curr_item._x = x;
            curr_item._y = y + i*curr_item._height;
            
        }
        curr_item.trackAsMenu = true;
        
        // item properties assigned from XML
        curr_node = node_xml.childNodes*;
        curr_item.action = curr_node.attributes.action;
        curr_item.variables = curr_node.attributes.variables;
        //curr_item.name.text = curr_node.attributes.name;
        curr_item.txt = curr_node.attributes.name;
        
        // item submenu behavior for rollover event
        if (node_xml.childNodes*.nodeName == "menu"){
            // open a submenu
            curr_item.node_xml = curr_node;
            curr_item.onRollOver = curr_item.onDragOver = function(){
                this.gotoAndStop("over");
                if(this._parent._name == "mainmenu_mc"){
                    var x = this._x+1;
                    var y = this._y + this._height ;
                }
                else{
                    var x = this._x + this._width - 3 ;
                    var y = this._y;
                }
                GenerateMenu(curr_menu, "submenu_mc", x, y, 1000, this.node_xml);
