How to remove xmlns attribute from XDocument?

Question

In my C # code base, I have XDocumentforms:

<A>
 <B>
   <C xmlns='blabla' yz='blablaaa'> Hi </C>
   <D xmlns='blabla' yz='blablaaa'> How </D>
   <E xmlns='blabla' yz='blablaaa'> Are </E>
   <F xmlns='blabla' yz='blablaaa'> You </F>
 </B>
 <B>
   <C xmlns='blabla' yz='blablaaa'> I </C>
   <D xmlns='blabla' yz='blablaaa'> am</D>
   <E xmlns='blabla' yz='blablaaa'> fine</E>
    <F xmlns='blabla' yz='blablaaa'> thanks</F>
 </B>

Using Linq-to-XML or otherwise, I wanted to delete xmlnsfor all elements contained in element B.

Using the methodology here: How to remove specific attributes in an XMLDocument? I managed to remove all attributes except xmlns

What is the best way to remove the xmlns attribute from XDocument?
