Change the Namespace and Root Node Name

Question

Hi,
I have following xml :
<ns2:Students xmlns:ns2="http://MyProject.CommonSchema">
    <ns2:Student>
      <HeaderSegment>
        <FName>AA</FName>
        <LName>AA</LName>
      </HeaderSegment>
    </ns2:Student>
  </ns2:Students>
Now I want to change the root node name and namespace name.
I want the following output:
<ns2:MyStudents xmlns:ns2="http://MyProject.MySchema">
    <ns2:Student>
      <HeaderSegment>
        <FName>AA</FName>
        <LName>AA</LName>
      </HeaderSegment>
    </ns2:Student>
  </ns2:Students>
I searched on the google but not found any right solution.
Any kind of help would be appreciated.

You should have told us that you wanted an XmlDocument. Anyway, you could use a XDocument to create and modify the XML and then return an XmlDocument like this:
public static XmlDocument CreateXmlDocument(string xml) {
//load the XML data
XDocument doc = XDocument.Parse(xml); //or use XDocument.Load to load a file
//change from old to the new namespace:
XNamespace newNs = "http://MyProject.MySchema";
var elemens = doc.Root.Elements();
foreach (var elem in doc.Root.Elements()) {
if (elem.Name.Namespace != string.Empty) {
elem.Name = newNs + elem.Name.LocalName;
//remove old namespace attribute:
XAttribute atr = doc.Root.Attributes(XNamespace.Xmlns + "ns2").FirstOrDefault();
if (atr != null)
atr.Remove();
//add the new namespace
doc.Root.Add(new XAttribute(XNamespace.Xmlns + "ns2", newNs));
doc.Root.Name = newNs + "Students2";
string newXml = doc.ToString();
XmlDocument xmlDocument = new XmlDocument();
using (var xmlReader = doc.CreateReader()) {
xmlDocument.Load(xmlReader);
return xmlDocument;
Usage:
string xml = "<ns2:Students xmlns:ns2=\"http://MyProject.CommonSchema\"><ns2:Student><HeaderSegment><FName>AA</FName><LName>AA</LName></HeaderSegment></ns2:Student></ns2:Students>";
XmLDocument doc = CreateXmlDocument(xml);
