ActionScript 3.0 :: Automating Multi-file Flash Using XML File "run List"

I've created a multi-file interactive Flash "demo" for a client. It's very much like a website (though he's not using it as a website) in the way that it is laid out in that there is a main index page which can then direct you to different product categories, which you can click on to see. Each "page" contains product (or product category) information, photos, block diagrams, etc. There is nothing animated in the Flash.
 
My client also wants to be able to set it up so that the demo runs automatically from a configurable XML file. My ActionScript skills are pretty limited, but I've been able to using ActionScript 3 to load and read the XML file. Using a 'for' loop, I am able to read the XML file and return the path of each Flash file and the duration that each file should be displayed (my client requested that he be able to configure the duration of each page as well).
 
I've set up a loader for each movie clip and a timer for the display duration. Unfortunately, the thing that is throwing me off is that when I attempt to load the movie clip (as the last item in the for loop), it reads the entire XML file, returns all of the clips and durations (I'm using trace to see this) before it loads the movie clip. As a result, the only movie clip that is loaded is the last one read from the XML file.
 
As I said, I'm not very good at ActionScript, so everything that I've managed to cobble together has been from internet tutorials.
 
This is my code:
 
var xmlLoader:URLLoader = new URLLoader();
xmlLoader.addEventListener(Event.COMPLETE, xmlLoaded); 
var mcLoader:Loader = new

[Code].....
 
I removed the timer event because it, like everything else was getting repeated before anything got loaded, so I wanted to figure out out to get the clip loader (mcLoader) to load the movie clip for each file before I figured out where to put the time to ensure that each clip is displayed for the appropriate duration. I suspect that the timer event needs to occur in the 'playClip' function, but would take advice on that as well.
