public class xmldisplay {
public static void  main(String args[]){
  try{
    DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
    DocumentBuilder builder=factory.newDocumentBuilder();
    Document doc=builder.parse("links.xml");
    doc.normalize();
    NodeList links =doc.getElementsByTagName("link");
    for (int i=0;i<links.getLength();i++){
      Element link=(Element) links.item(i);
      System.out.print("Content: ");
      System.out.println(link.getElementsByTagName("text").item(0).getFirstChild().getNodeValue());
      System.out.print("URL: ");
