From source file:Main.java

public static void main(String[] args) throws Exception {
    DocumentBuilderFactory docBuilderFactory = DocumentBuilderFactory.newInstance();
    DocumentBuilder docBuilder = docBuilderFactory.newDocumentBuilder();
    Document doc = docBuilder.parse(new File("D:/test.xml"));

    NodeList elt = doc.getElementsByTagName("EMPLOYEE");
    for (int k = 0; k < elt.getLength(); k++) {
        Node firstNode3 = elt.item(k);
        Element elt1 = (Element) firstNode3;
        String att = elt1.getAttribute("PERMANENT");
        System.out.println("\n\nPERMANENT: " + att);

        NodeList nodes = elt1.getElementsByTagName("DETAILS");
        for (int i = 0; i < nodes.getLength(); i++) {
            Node childNode = nodes.item(i);
            Element elt2 = (Element) childNode;
            System.out.println("---" + elt2.getNodeName());
            System.out.println("NAME:" + elt2.getAttribute("NAME"));
            System.out.println("ID:" + elt2.getAttribute("ID"));
            System.out.println("AGE:" + elt2.getAttribute("AGE"));
        }// ww  w.  j  a va2 s  . c o  m
    }
}
