Creation of GUI from contents of xml file

Hi,

I have an xml file containing a list of items as-

<?xml version="1.0"?>
<catalog>
<book id="bk101">
<author>Gambardella, Matthew</author>
<title>XML Developer's Guide</title>
<genre>Computer</genre>
<price>44.95</price>

</book>
<book id="bk103">

</book>
</catalog>

My question is: How do I code in java in order to display this in a tree structure in a GUI?

It should be displayed as:

bk105
Gambardella, Matthew

Computer

bk102

A former architect battles corporate zombies, an evil sorceress, and her own childhood to become queen of the world.

Added to it, there should be an option to expand and compress the contents of the tree also.
