import org.xml.sax.InputSource;

public class Main {
  public static void main(String[] argv) throws Exception {
    DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();

    InputSource is = new InputSource();
    is.setCharacterStream(new StringReader(xmlRecords));
    
    Document doc = factory.newDocumentBuilder().parse(is);

    CDATASection cdataNode = doc.createCDATASection("");

    CharacterData cdata = cdataNode;

    
    cdata.setData("from java2s.com");
    System.out.println(cdataNode.substringData(2, 4));
  }
  static String xmlRecords = "<data></data>";
