  public static void main(String arg[]) throws Exception{

String xmlRecords = “<data><employee><name>A</name>”
+ “<title>Manager</title></employee></data>”;


    DocumentBuilder db = DocumentBuilderFactory.newInstance().
newDocumentBuilder();
    InputSource is = new InputSource();
    is.setCharacterStream(new StringReader(xmlRecords));


    Document doc = db.parse(is);
    NodeList nodes = doc.getElementsByTagName("employee");


    for (int i = 0; i < nodes.getLength(); i++) {
      Element element = (Element) nodes.item(i);
