namespace VTDTest
{
   class Program
   {
       static void Main(string[] args)
       {
           try
           {
               // open a file and read the content into a byte array
               VTDGen vg = new VTDGen();
               if
(vg.parseFile("./c82ebc4258954b01aa938174ad26af7b.xml", true))
               {
                   VTDNav vn = vg.getNav();
                   AutoPilot ap = new AutoPilot(vn);

//ap.selectElementNS("http://purl.org/dc/elements/1.1/", "*"); //
select name space here; * matches any local name
                   ap.selectElement("*");
                   int count = 0;
                   while (ap.iterate())
                   {
                       Console.Write("" + vn.getCurrentIndex() + "  ");
                       Console.WriteLine("Element name ==> " +
vn.toString(vn.getCurrentIndex()));
                       int t = vn.getText(); // get the index of the
text (char data or CDATA)
                       if (t != -1)
                           Console.WriteLine(" Text  ==> " +
vn.toNormalizedString(t));
                       Console.WriteLine("\n ============================== ");
                       count++;
                   }
                   Console.WriteLine("Total # of element " + count);
                   Console.ReadKey();
               }
               else
                   Console.WriteLine("ee");
           }
           catch (NavException e)
