Java：如何在JTree中显示XML文件

这是我使用的代码。它基于Dom4J的API，但是您可以轻松地将其转换为您喜欢的XML库的API：

public JTree build(String pathToXml) throws Exception {     SAXReader reader = new SAXReader();     document doc = reader.read(pathToXml);     return new JTree(build(doc.getRootElement()));}public DefaultMutableTreeNode build(Element e) {   DefaultMutableTreeNode result = new DefaultMutableTreeNode(e.getText());   for(Object o : e.elements()) {      Element child = (Element) o;      result.add(build(child));   }   return result;         }
