removing/extracting soap header and body from soap message

I have a soap message shown below. I would like to get only request element and its child nodes. 

<?xml version="1.0" encoding="UTF-8"?>
<soap:Envelope xmlns:soap="http://www.w3.org/2003/05/soap-envelope"
               xmlns:xlink="http://www.w3.org/1999/xlink" 
               xmlns:ds="http://www.w3.org/2000/09/xmldsig#" 
               xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
               xsi:schemaLocation="http://location.xsd">
  <soap:Header xmlns="http://www.server.net/schema/request.xsd">
  </soap:Header>
  <soap:Body>
   <Request ReqRespVersion="large" Version="1" EchoToken="1.0" xmlns="http://mynamespace.com">
     .....
   </Request>
 </soap:Body>
</soap:Envelope>

I am able to get it using this code.

Dim myXDocument As XDocument = XDocument.Load(New StringReader(Request))
Dim Xns As XNamespace = XNamespace.Get("http://mynamespace.com")
SoapBody = myXDocument.Descendants(Xns + "Request").First().ToString

But I dont want to use specific name like "Request" because I have more than soap messages and each have different xml element name. so I need a general function instead of making a specific function for each.

I followed that suggestion(s): Extract SOAP body from a SOAP message

but with this code below, but it doesnt work for me. where am I doing the mistake or how do I extract inside the body part?

Dim myXDocument As XDocument = XDocument.Load(New StringReader(Request))
Dim Xns As XNamespace = XNamespace.Get("soap="http://www.w3.org/2003/05/soap-envelope")
SoapBody = myXDocument.Descendants(Xns + "Body").First().ToString

You have the wrong namespace in your second example, and you didn't follow the complete example from the linked answer.

XNamespace.Get("soap="http://www.w3.org/2003/05/soap-envelope")

The parameter passed in to XNamespace.Get should be the URI only:

XNamespace.Get("http://www.w3.org/2003/05/soap-envelope")

Then your second example will return something like:

<soap:Body xmlns:soap="http://www.w3.org/2003/05/soap-envelope">
  <Request ReqRespVersion="large" Version="1" EchoToken="1.0" xmlns="http://mynamespace.com">
  </Request>
</soap:Body>

If you want just the child(ren) elements of the Body, then you need to add FirstNode like this:

SoapBody = myXDocument.Descendants(Xns + "Body").First().FirstNode.ToString()

Which will give you this:

<Request ReqRespVersion="large" Version="1" EchoToken="1.0" xmlns="http://mynamespace.com">
</Request>
