Hi
Follow the steps .
This is the XML file .
<?xml version="1.0"?>
<company>
     <employee>
          <firstname>Tom</firstname>
          <lastname>Cruise</lastname>
     </employee>
     <employee>
          <firstname>Paul</firstname>
          <lastname>Enderson</lastname>
     </employee>
     <employee>
          <firstname>George</firstname>
          <lastname>Bush</lastname>
     </employee>
</company>
Java Code of this to fetch the details.
public class XMLReader {
public static void main(String argv[]) {
  try {
  File file = new File("c:\\MyXMLFile.xml");
  DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
  DocumentBuilder db = dbf.newDocumentBuilder();
  Document doc = db.parse(file);
  doc.getDocumentElement().normalize();
  System.out.println("Root element " + doc.getDocumentElement().getNodeName());
  NodeList nodeLst = doc.getElementsByTagName("employee");
  System.out.println("Information of all employees");
  for (int s = 0; s < nodeLst.getLength(); s++) {
    Node fstNode = nodeLst.item(s);
    if (fstNode.getNodeType() == Node.ELEMENT_NODE) {
           Element fstElmnt = (Element) fstNode;
      NodeList fstNmElmntLst = fstElmnt.getElementsByTagName("firstname");
      Element fstNmElmnt = (Element) fstNmElmntLst.item(0);
      NodeList fstNm = fstNmElmnt.getChildNodes();
      System.out.println("First Name : "  + ((Node) fstNm.item(0)).getNodeValue());
      NodeList lstNmElmntLst = fstElmnt.getElementsByTagName("lastname");
      Element lstNmElmnt = (Element) lstNmElmntLst.item(0);
      NodeList lstNm = lstNmElmnt.getChildNodes();
      System.out.println("Last Name : " + ((Node) lstNm.item(0)).getNodeValue());
  } catch (Exception e) {
    e.printStackTrace();
