SelectSingleNode from SOAP Response

Hi

I need to get the InnerText from the following xmlfile ( From "NodeB")

<?xml version="1.0" encoding="utf-8"?>
<soap:Envelope xmlns:soap="http://www.w3.org/2003/05/soap-envelope&quot; xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance&quot; xmlns:xsd="http://www.w3.org/2001/XMLSchema"&gt;
  <soap:Body>
    <NodeA>xmlns="https://xxxxxxxxxx.com/"&gt;
      <NodeB>NEED TO GET THIS TEXT</NodeB>
    </NodeA>
  </soap:Body>
</soap:Envelope>

I have the XMLFile in a System.Xml.XmlDocument .DOTNET var. ( And in a Instream )


My first idea was to use codeunit 6224
Then use DOTNET

I have tried to google a lot


Someone that can help me out here..

THANKS
