My XML document:
www.llcrew.com/test/xml/discography.xml
My PHP script:
www.llcrew.com/test/xml/index.php
I'm trying to display the tracks of each release seperately. However, my current script is displaying the tracks (for all releases combined). Here is my source:
<head>
<title>Discography</title>
<link rel="stylesheet href="../styles/stand.css" type="text/css">

<body bgcolor="#ffffff" topmargin="10" leftmargin="10" marginheight="10" marginwidth="10">
