Accessing character data or CDATA of XML element in JAVA

This code snippet will help to access character data of xml file while parsing it through java using SAX Parser.

import java.util.Stack;

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

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

public class Main extends DefaultHandler {
  private Stack currentElement = new Stack();

  public void startElement(String uri, String localName, String qName, Attributes attrs)
      throws SAXException {
    currentElement.push(qName);
  }

  public void endElement(String namespaceURI, String localName, String qName) throws SAXException {
    currentElement.pop();
  }

  public void characters(char[] ch, int start, int length) throws SAXException {
    String cdata = new String(ch, start, length);
    System.out.println("Element '" + currentElement.peek() + "' contains text: " + cdata);
  }

  public static void main(String[] args) throws Exception {
    SAXParserFactory factory = SAXParserFactory.newInstance();
    factory.setValidating(true);
    SAXParser parser = factory.newSAXParser();
    parser.parse("sample.xml", new Main());
  }
}
