使用SAX在Java中解析自定义XML响应

import org.xml.sax.Attributes;
import org.xml.sax.SAXException;
import org.xml.sax.helpers.DefaultHandler;
import javax.xml.parsers.SAXParser;
import javax.xml.parsers.SAXParserFactory;

public class CustomXMLParser {

    public static void main(String[] args) {
        try {
            // 创建SAXParserFactory对象
            SAXParserFactory factory = SAXParserFactory.newInstance();
            // 创建SAXParser对象
            SAXParser parser = factory.newSAXParser();
            // 创建自定义的DefaultHandler对象
            CustomHandler handler = new CustomHandler();
            // 使用SAXParser解析XML文件，并传入自定义的DefaultHandler对象
            parser.parse("custom.xml", handler);
        } catch (Exception e) {
            e.printStackTrace();
        }
    }

    // 自定义的DefaultHandler类
    private static class CustomHandler extends DefaultHandler {

        @Override
        public void startElement(String uri, String localName, String qName, Attributes attributes) throws SAXException {
            // 处理元素开始事件
            System.out.println("Start Element: " + qName);
        }

        @Override
        public void endElement(String uri, String localName, String qName) throws SAXException {
            // 处理元素结束事件
            System.out.println("End Element: " + qName);
        }

        @Override
        public void characters(char[] ch, int start, int length) throws SAXException {
            // 处理元素内容事件
            String content = new String(ch, start, length);
            System.out.println("Element Content: " + content);
        }
    }
}
