You can get a string array containing the 6 attribute values using LINQ to XML as follows:

using System.Linq;

using System.Xml.Linq;

using System.IO;

// ...

XElement root = XElement.Load("maha.xml");

string[] values = root.Element("Serial").Element("Current").Attributes().Select(a => 

a.Value).ToArray();

You should find that:

values[0] will contain : 11 March 2011

values[1] will contain : 10 Rabi-Ul-Awal 1434

and so on.

It's then just a matter of assigning the appropriate values to your textblocks.
