Java JTree / Prestashop categories

I am not familiar with JTree component and XML. I Have an XML File which represents Categories in Prestashop ecommerce platform : 

<?xml version="1.0" encoding="UTF-8"?>
<prestashop xmlns:xlink="http://www.w3.org/1999/xlink">

I could not change XML file format because it's generated by prestashop webservices. What I would like to do is to populate a JTree with all my categories inside the XML with hierarchical.

For example, here you have Firt one : "Racine". Under Racine, you have "Accueil". The result should be : 

Racine
    Accueil
        Télécommande
        Audio-Vidéo
            Casque Yurbuds
        Multimédia

How could I do that ? Thanks

Solution

  • Found a solution.

    Create a class "MyTreeModel" which implements TreeModel. Inside this class, add an Object that represents my category. Get all childs of Categories and add to a HashMap with

    Contruct a JTree with MyTreeModel as parameter. Voilà
