Listing all nodes from a xml sheet

programming flash
1

Alo all

Ive got an xml sheet that is 3 levels deep (part example below)

<flashNav>
   <navItem itemName="1" itemPath="" itemClip="">
          <navItem itemName="1.1" itemPath="" itemClip="">
               <navItem itemName="1.1.1" itemPath="" itemClip=""/>
               <navItem itemName="1.1.2" itemPath="" itemClip=""/>
               <navItem itemName="1.1.3" itemPath="" itemClip=""/>
               <navItem itemName="1.1.4" itemPath="" itemClip=""/>
          </navItem>
          <navItem itemName="1.2" itemPath="" itemClip="">
          <navItem itemName="1.3" itemPath="" itemClip="">
          <navItem itemName="1.4" itemPath="" itemClip="">
               <navItem itemName="1.4.1" itemPath="" itemClip=""/>
          </navItem>
</navItem>
</flashNav>

That i want to read into an array in sequental order.

At the moment i can only get the first level showing up with the following code:

var menuItems = this.firstChild;
		for (var i = 0; i<menuItems.childNodes.length; i++) {
			menuTitles.push(menuItems.childNodes*.attributes.itemName);
			menuLinks.push(menuItems.childNodes*.attributes.itemPath);
		}
		trace(menuItems.childNodes.length);

How would i go about adding the rest of the nodes into the array?
