Question

我不熟悉JTree组件和XML。我有一个XML文件，代表Prestashop电子商务平台中的类别：

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

我无法更改XML文件格式，因为它是由prestashop webservices生成的。我想要做的是使用层次结构在XML中填充我的所有类别的JTree。

例如，这里有第一个：“拉辛”。在拉辛下，你有“Accueil”。结果应该是：

Racine
    Accueil
        Télécommande
        Audio-Vidéo
            Casque Yurbuds
        Multimédia

我怎么能这样做？感谢

找到解决方案。

创建一个实现TreeModel的类“MyTreeModel”。在此类中，添加一个表示我的类别的Object。获取所有类别的子项并使用

添加到HashMap

使用MyTreeModel构造一个JTree作为参数。瞧
