Welcome to TheScripts TSDN...

You may use XMLDocument class.
See these links:
Manipulate XML data with XPath and XmlDocument
and
Modify XML Data by Using DOM in .NET Framework

You need to use SelectSingleNode() method and to update the InnerText property of the selected XmlNode. Then call the Save() method.

I hope to succeed. Otherwise, let us know.

but i have all the time node = null that means that something in the Xpath Query is incorrect
