Loading JPGs from XML depending on date

Hi all!

I've been looking around to find out exactly how I can dynamically
load JPGs as the background to a flash movie I'm working on, which are
displayed based on date, i.e. they are diaplyed only until the enddate defined in the XML file.
I saw a post where an external XML file was used and this is the way I
want to go.
The file should be something like the following:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE images SYSTEM "promo.dtd">
<images>
<photos>
<img>foto1.jpg</img>
<startdate>01/11/2003</startdate>
<enddate>30/11/2003</enddate>
</photos>
<photos>
<img>foto2.jpg</img>
<startdate>01/12/2003</startdate>
<enddate>31/12/2003</enddate>
</photos>
</images>

As a complete novice actionscripter I dont know where to start at
reading this XML and then dispalying the image, so any help is much
appreciated.
I have 52 images - one per week for 2004.

Thanks!
