Hello Friend,

Simply use foreach loop to traverse through each element.
foreach (XElement somename in element.Descendants("filename"))
                {
               foreach (XElement item in n.Descendants())
                    {
                        //get value of all child nodes for your file
                  }
              }

for more detail visit MSDN site having good examples
Regards
D

there is one more simple way to retrieve all elements,like this

XDocument nameofDoc= new XDocument("path");
foreach (var xelem  in contact.Elements()) 
{
 Console.WriteLine(xelem.Name().ToString());
 }


Hope it helps!!
Regards

hi,

Try this below code for traverse each and every element from and existing XML
foreach (var element in doc.Descendants()) {
    Console.WriteLine(element.Name);
    foreach (var attribute in element.Attributes()) {
      Console.WriteLine("> " + attribute.Name + " = " + attribute.Value);
    }
  }
