使用SAX解析器解析XML时，需要获取元素标签的值

import org.xml.sax.Attributes;
import org.xml.sax.SAXException;
import org.xml.sax.helpers.DefaultHandler;

public class MyHandler extends DefaultHandler {
    private String currentElement;
    private String currentValue;

    @Override
    public void startElement(String uri, String localName, String qName, Attributes attributes) throws SAXException {
        currentElement = qName;
    }

    @Override
    public void characters(char[] ch, int start, int length) throws SAXException {
        currentValue = new String(ch, start, length);
    }

    @Override
    public void endElement(String uri, String localName, String qName) throws SAXException {
        if (currentElement.equals(qName)) {
            System.out.println("Element: " + currentElement);
            System.out.println("Value: " + currentValue);
        }
    }
}
