XML load image

I’m trying to modify an XML jukebox by adding an artwork functionality to it. The problem is that the jukebox is a component so I’m not able to pull it to pieces. I would like to use the same XML file though to add an extra variable (is that the right term?) called artwork.

Here is the modified XML:

<?xml version=“1.0” encoding=“utf-8” ?>
<mp3s>
<file name=“Song 1” file=“song1.mp3” artwork=“song1.jpg” />
</mp3s>

I’m having a little trouble finding a similar XML example with similar formatting so am a little confused as to what nodes/childs etc are in terms of this file. If I wanted to use loadMovie to load the song1.jpg into an empty movieclip - what is the actionscript I need?
