如何在 JTree 中的节点旁边显示特定的属性名称和值？

Question

我想在 JTree 中的节点名称旁边显示属性的名称和值。谁能告诉我该怎么做？这是我用来显示 JTree 的代码：

import javax.swing.*;
import java.awt.*;
import java.awt.event.*;
import java.awt.Event.*;
import java.io.*;
import javax.swing.tree.*;
import org.xml.sax.*;
import org.xml.sax.helpers.*;
import org.apache.xerces.parsers.*;

public class XMLTreeView {

    private SAXTreeBuilder saxTree = null;
    private static String file = "";

    public static void main(String args[]) {
        JFrame frame = new JFrame("XMLTreeView: [ games.xml ]");
        frame.setSize(400, 400);

        frame.addWindowListener(new WindowAdapter() {
            public void windowClosing(WindowEvent ev) {
                System.exit(0);
            }
        });
        file = "example1.xml";
        new XMLTreeView(frame);
    }

    public XMLTreeView(JFrame frame) {
        frame.getContentPane().setLayout(new BorderLayout());
        DefaultMutableTreeNode top = new DefaultMutableTreeNode(file);
//              DefaultMutableTreeNode top = new DefaultMutableTreeNode("XML Document"); 
        saxTree = new SAXTreeBuilder(top);
        try {
            SAXParser saxParser = new SAXParser();
            saxParser.setContentHandler(saxTree);
            saxParser.parse(new InputSource(new FileInputStream(file)));
        } catch (Exception ex) {
            top.add(new DefaultMutableTreeNode(ex.getMessage()));
        }
        JTree tree = new JTree(saxTree.getTree());
        JScrollPane scrollPane = new JScrollPane(tree);

        frame.getContentPane().add("Center", scrollPane);
        frame.setVisible(true);
    }
}

class SAXTreeBuilder extends DefaultHandler {

    private DefaultMutableTreeNode currentNode = null;
    private DefaultMutableTreeNode previousNode = null;
    private DefaultMutableTreeNode rootNode = null;

    public SAXTreeBuilder(DefaultMutableTreeNode root) {
        rootNode = root;
    }

    public void startDocument() {
        currentNode = rootNode;
    }

    public void endDocument() {
    }

    public void characters(char[] data, int start, int end) {
        String str = new String(data, start, end);
        if (!str.equals("") && Character.isLetter(str.charAt(0))) {
            currentNode.add(new DefaultMutableTreeNode(str));
        }
    }

    public void startElement(String uri, String qName, String lName, Attributes atts) {
        previousNode = currentNode;
        currentNode = new DefaultMutableTreeNode(lName);
        // Add attributes as child nodes //
        attachAttributeList(currentNode, atts);
        previousNode.add(currentNode);
    }

    public void endElement(String uri, String qName, String lName) {
        if (currentNode.getUserObject().equals(lName)) {
            currentNode = (DefaultMutableTreeNode) currentNode.getParent();
        }
    }

    public DefaultMutableTreeNode getTree() {
        return rootNode;
    }

    private void attachAttributeList(DefaultMutableTreeNode node, Attributes atts) {
        for (int i = 0; i < atts.getLength(); i++) {
            String name = atts.getLocalName(i);
            String value = atts.getValue(name);
            node.add(new DefaultMutableTreeNode(name + " = " + value));
        }
    }
}

在JTree中，我想在NE节点旁边显示NEType属性，在EQHO节点[=21]旁边显示equipmentHolderType属性=]

NE NEType=WBTS
    EQHO equipmentHolderType=Subrack

我想要这样的东西:

您可以更改用于构造树节点的字符串：

public void startElement(String uri, String qName, String lName, Attributes atts) {
    previousNode = currentNode;
    // Use the result of the getNodeText method to construct the tree node.
    currentNode = new DefaultMutableTreeNode(getNodeText(lName, atts));
    // Add attributes as child nodes //
    attachAttributeList(currentNode, atts);
    previousNode.add(currentNode);
}

private String getNodeText(final String lName, final Attributes atts) {
    final String postfix;

    if ("NE".equals(lName) && atts.getValue("NEType") != null)
        postfix = " NEType=" + atts.getValue("NEType");
    else if ("EQHO".equals(lName) && atts.getValue("equipmentHolderType") != null)
        postfix = " equipmentHolderType=" + atts.getValue("equipmentHolderType");
    else
        postfix = "";

    return lName + postfix;
}

在下面的变体中，我使用了 javax.xml.parsers、修改后的 getNodeText() 和更新后的 xml。
