How to update an XML node with LINQ?

How do we update the a node name with a new value using LINQ?

<test xmlns="http://www.mydomain.com/test/xyz" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" version="1.0">
  <Ribbon1>test</Ribbon1>
  <Ribbon2>test</Ribbon2>
</test>

I was trying as below:

var query = from lst in XElement.Load(fileLoc).Elements(ns + "Ribbon1")
            select lst.FirstNode ;

The below code is working now:

XNamespace ns = @"http://www.mydomain.com/test/xyz";
XElement xElement = XElement.Load(fileLoc);
foreach (XElement descendant in xElement.Descendants(ns + "Ribbon1"))
    descendant.Value = "Borra";
xElement.Save(fileLoc);

Your code use Elemnts and that only looks at the given level. To find something at an arbitrary level:

//XElement.Load(fileLoc).Elements(ns + "Ribbon1")
XElement.Load(fileLoc).Descendants(ns + "Ribbon1")

or to adhere to the structure:

XElement.Load(fileLoc).Element(ns + "test").Elements(ns + "Ribbon1")

be careful about Element() and Elements()
