Xml and arrays

hi,
ive been workin on an app to display different musical projects that my brothers and i have worked on. i want to have all info in one xml file but have been having a tough time thinking of an efficient way to travese the <tracks> nodes.

<album>[INDENT] <name></name>
<artists></artists>
<tracks>[INDENT] <track>[INDENT] <title></title>
<mood></mood>
[/INDENT]</track>
<track>[INDENT] <title></title>
<mood></mood>
[/INDENT]</track>
[/INDENT]</tracks>
[/INDENT]</album>

im thinking it best to turn out to be some sort of double array (like album[1].name, album[1].artist, album[1].tracks[2].mood ?) but my AS knowledge doesnt take me far enough to solve this. but thats why im here!
any help would be great.

if that array idea is correct, can anyone help me firgure out how to implement it?
thanks you,
yiannis
