JAXB 很好用，直到我需要做一些复杂的事情。有哪些替代方案

JAXB（Java Architecture for XML Binding）是一个Java库，可以将XML文档和Java对象之间进行转换。它提供了简单易用的方式来处理XML数据。然而，当需要处理一些复杂的任务时，JAXB可能会显得有些不足。在这种情况下，可以考虑使用其他替代方案来完成这些复杂的任务。本文将介绍几种替代方案，并提供相应的案例代码。

java
import org.w3c.dom.*;
import javax.xml.parsers.*;
import java.io.*;
public class DOMExample {
    public static void main(String[] args) {
        try {
            File xmlFile = new File("example.xml");
            DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
            DocumentBuilder builder = factory.newDocumentBuilder();
            Document document = builder.parse(xmlFile);
            
            Element rootElement = document.getDocumentElement();
            NodeList nodeList = rootElement.getElementsByTagName("name");
            
            for (int i = 0; i < nodeList.getLength(); i++) {
                Element element = (Element) nodeList.item(i);
                String name = element.getTextContent();
                System.out.println("Name: " + name);
            }
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}

java

import org.xml.sax.helpers.*;
import java.io.*;
public class SAXExample {
    public static void main(String[] args) {
        try {
            File xmlFile = new File("example.xml");

                public void characters(char[] ch, int start, int length) throws SAXException {
                    if (nameElement) {
                        String name = new String(ch, start, length);
                        System.out.println("Name: " + name);
                        nameElement = false;
                    }
                }
            });
            
            xmlReader.parse(new InputSource(new FileInputStream(xmlFile)));
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}
