如何在xml中转换字符串并循环Node？

import org.w3c.dom.*;
import javax.xml.parsers.*;
import java.io.*;

public class XMLParser {
    public static void main(String[] args) {
        try {
            // 将字符串转换为XML文档对象
            String xmlString = "<root><node1>Value 1</node1><node2>Value 2</node2></root>";
            DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
            DocumentBuilder builder = factory.newDocumentBuilder();
            Document document = builder.parse(new InputSource(new StringReader(xmlString)));

            // 循环遍历节点
            NodeList nodeList = document.getDocumentElement().getChildNodes();
            for (int i = 0; i < nodeList.getLength(); i++) {
                Node node = nodeList.item(i);
                if (node.getNodeType() == Node.ELEMENT_NODE) {
                    // 执行相应的操作，例如获取节点值
                    String nodeName = node.getNodeName();
                    String nodeValue = node.getTextContent();
                    System.out.println("Node Name: " + nodeName);
                    System.out.println("Node Value: " + nodeValue);
                }
            }
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}
