Thanks for your help
For get the the tree in expanded form, I am using the expandAPath funtion by the following way.
public class XMLTreePanel extends JPanel {
       private JTree tree;
       private XMLTreeModel model;
       public XMLTreePanel() {
                setLayout(new BorderLayout());
        model = new XMLTreeModel();
     tree = new JTree();
     tree.setModel(model);
     tree.setShowsRootHandles(true);
     tree.setEditable(false);
     expandAPath(tree);
     JScrollPane pane = new JScrollPane(tree);
     pane.setPreferredSize(new Dimension(300,400));
     add(pane, "Center");
     final JTextField text = new JTextField();
                text.setEditable(false);
     add(text, "South");
     tree.addTreeSelectionListener(new TreeSelectionListener() {
          public void valueChanged(TreeSelectionEvent e) {
          Object lpc = e.getPath().getLastPathComponent();
          if (lpc instanceof XMLTreeNode) {
               text.setText( ((XMLTreeNode)lpc).getText() );
public void expandAPath(JTree tree){               
     for(int i=1; i<tree.getRowCount(); ++i) {
          tree.expandRow(i);            
public void setDocument(Document document) {
     model.setDocument(document);
public Document getDocument() {
     return model.getDocument();
}
