Linq to XML, C# -

i have xml in xdocument object (linq xml). need add namespace each xelement/node in xdocument.

i dont want add in below way. beceause have xml in xdoc.

xdocument xdoc = new xdocument( new xelement(ns + "root", new xelement(ns + "person", new xattribute("id", 1), new xelement(ns + "firstname", "jack"), 

below format have

<root>   <person>1</person>   <firstname>jack</firstname> </root>
