XElement Displaying Child Node of parent if parent Empty

Question

Hello guys is there any way that i can force in the final output to Display the Empty ChildNodes of the parent Node. The thing is since all the Child nodes of the parent node are Empty i am getting this output (this is just a segment of my XML):

 

<fpc::Header>

<fpc:Data>?fpc:Data>

 

and i want to be displayed like this through all the nodes where this happens:

 

<fpc:Header>

<fpc:Data>

<fpc:Id>?fpc:Id>

<fpc:Access>?</fpc:Access>

<fpc:Password>?</fpc:Password>

>

 

and this is the code:

 

foreach (XElement child in body.DescendantNodes().OfType().ToList())

{

child.Name = nsCsdb.GetName(child.Name.LocalName);

if (String.IsNullOrWhiteSpace(child.Value) || child.IsEmpty)

child.ReplaceWith(new XElement(child.Name, "?"));

}

 

so how can i enforce this to generate my soap Envelope as desired?

PS: ahh i am replacing self-closing tags to the normal start and end tag that's why the creation of the new XElement
