Additional error information:

SOLUTION: This is because the node to be copied belongs to another Xml document and is not recognized by the destination xml document. In order to make it work, you will need to import it first. If you read MSDN's documentation for the XmlNode.AppendChild() method, you will notice the following description:

...
If the node being inserted was created from another document, you can use XmlDocument.ImportNode to import the node to the current document. The imported node can then be inserted into the current document. ...

Therefore, all you need to do is to add XmlDocument.ImportNode() method in the message assignment expression editor:

Construct MsgB

{

    theXmlDoc.DocumentElement.AppendChild

    (

       theXmlDoc.ImportNode

       (

           xpath

           (

               MsgA,

               "//*[local-name()='someElement']"

           )

       )

    );

    MsgB = theXmlDoc;
