Found different forum threats with comments “super root correct” or “invalid XML structure” but don´t find any problems in my code. HTML is very easy and XML too (snip from your samples).
Tested with FF, IE and chrome

[/code]XML:
<?xml version="1.0" encoding="UTF-8"?>
<tree id="root">
<item text="Books" id="books" open="1">
<item text="Mystery & Thrillers" id="mystery">
