Change Movie Clips from XML file

programming flash
1

I have a gallery I am trying to update. It’s in AS2.
Basically the gallery has full size images, some are light, some are dark. I have 2 logos, one for the light images, one for the dark. Can you tell me how I would write a function or create a vraible so I could tell which movieclip to be ‘on’ and fade up, while fading the other one down, and do it from the same xml that loads the images?

Here’s the xml for the images:

<?xml version=“1.0” encoding=“utf-8” ?>
<gallery>
<globals
nameColor="#FFFFFF" nameFontSize=“20” nameBgColor="#000000" nameBgAlpha=“40”
nameLocation=“top” namePosition=“left”
radius=“6” cssFile=“css/gallery.css”
/>
