How to parse an XML element root an select some values of it in Java?

I am looking for a practical way to parse an xml root element an get some values from it. I have tried many ways, but none of them are efficient.

       DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();

                Document doc = factory.newDocumentBuilder().parse(fileLoaded);

                Element root = null;

                NodeList list = doc.getChildNodes();
               System.out.println(list.toString());
                for (int i = 0; i < list.getLength(); i++) {
                  if (list.item(i) instanceof Element) {
                    root = (Element) list.item(i);
                    System.out.println(root.toString());
                    break;
                  }
                }
                root = doc.getDocumentElement();
              }

XML file:

    <planes_for_sale id="planeId" num="1452" name="boing">
    <ad>
      <year> 1977 </year>
      <make> test </make>
      <model> Skyhawk </model>
      <color> Light blue and white </color>
      <description> New paint, nearly new interior,
        685 hours SMOH, full IFR King avionics </description>
      <price> 23,495 </price>
      <seller phone = "555-222-3333"> Skyway Aircraft </seller>
      <location>
      <city> Rapid City, </city>
      <state> South Dakota </state>
  </location>

In my case I want to load id, num, name from planes_for_sale root element.

For anyone who is looking for a pratical way here is one tested :

    DocumentBuilderFactory factory = DocumentBuilderFactory
                    .newInstance();

            Document doc = factory.newDocumentBuilder().parse(fileLoaded);
            doc.getDocumentElement().normalize();
            System.out.println("Root element :"
                    + doc.getDocumentElement().getNodeName());
            NodeList nList = doc.getElementsByTagName("planes_for_sale");

              System.out.println("----------------------------");

                 for (int temp = 0; temp < nList.getLength(); temp++) {
                    Node nNode = nList.item(temp);
                    System.out.println("\nCurrent Element :" + nNode.getNodeName());
                    if (nNode.getNodeType() == Node.ELEMENT_NODE) {
                        Element eElement = (Element) nNode;
                        System.out.println("Plane name : " 
                           + eElement.getAttribute("name"));
                    }
                 }
