How to parse this XML using Java?

Java SAX API

import java.io.File;
import java.util.ArrayList;
import java.util.List;

import javax.xml.parsers.SAXParser;
import javax.xml.parsers.SAXParserFactory;

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

public class Main {
  public static void main(String[] args) throws Exception {
    SAXParserFactory factory = SAXParserFactory.newInstance();
      SAXParser saxParser = factory.newSAXParser();
      MyHandler myHandler = new MyHandler();
      saxParser.parse(new File("g:/temp/x.xml"), myHandler);

      for(Pair p : myHandler.result) {
        System.out.println(p.a + ":" + p.b);
      }
  }

  public static final class Pair {
    public final String a;
    public final String b;

    public Pair(String a, String b) {
      this.a = a;
      this.b = b;
    }
  }

  public static class MyHandler extends DefaultHandler {    
    public final List<Pair> result = new ArrayList<Pair>();
    private StringBuilder sb = new StringBuilder();

    @Override
    public void endElement(String uri, String localName, String qName)
        throws SAXException {
      String s = sb.toString().trim();
      if(s.length() > 0)
        result.add(new Pair(qName, s));
      sb = new StringBuilder();
    }

    @Override
    public void characters(char[] ch, int start, int length)
        throws SAXException {
      sb.append(ch, start, length);
    }
  }
}
