c# - Get rid of xmlns attribute when adding node to existing xml -

i have xml-file:

<ns2:root xmlns:ns2="namespace">     <ns2:a>         <ns2:b>some content</b>         <ns2:c>some content</c>         <ns2:d>some content</d>     </a> </root> 

i need add new node in specific place, code is:

var doc = xdocument.load(file); xnamespace ns2 = "namespace"; doc.element(ns2 + "root").element(ns2 + "a").element(ns2 + "c").addafterself(     new xelement(ns2+"new",          new xelement("new1",              new xelement("new2","some content"),             new xelement("new3", "some content")))); 

the output is:

<ns2:root xmlns:ns2="namespace">     <ns2:a>         <ns2:b>some content</b>         <ns2:c>some content</c>         <ns2:new>             <new1 xmlns="">                 <new2>some content</new2>                 <new3>some content</new3>             </new1>         </new>         <ns2:d>some content</d>     </a> </root> 

desired output is:

<ns2:root xmlns:ns2="namespace">     <ns2:a>         <ns2:b>some content</b>         <ns2:c>some content</c>         <ns2:new>             <new1>                 <new2>some content</new2>                 <new3>some content</new3>             </new1>         </new>         <ns2:d>some content</d>     </a> </root> 

how can avoid adding xmlns atrribute node new1?

edited mistake in desired output.

add "ns2 +" before every element name needs in sitemap namespace

var doc = xdocument.load(file); xnamespace ns2 = "namespace"; doc.element(ns2 + "root").element(ns2 + "a").element(ns2 + "c").addafterself(     new xelement(ns2+"new",          new xelement(ns2+"new1",              new xelement(ns2+"new2","some content"),             new xelement(ns2+"new3", "some content"))));
