Not exactly sure which code is correct as you have to return statements with two different types.

But if you want to have the contents of the XmlDocument you can one of the properties InnerXml or OuterXml, depending on what you want.

Maybe read some MSDN documentation.
XmlDocument.InnerXml Property[^]

return sw.ToString(); // Error shown here.

This means that you did not show us the code you actually use: before that line is a different return statement.

return WP_XMLdoc;

and that's a correct return statement. The statement where according to your words the error is shown will never be executed.

sw.ToString() returns a string. But the signature of the function says that the function returns an XMLDocument, hence the compiler tries to cast the string to XMLDocument, and that is not possible. To get an XMLDocument from a string, you can use the LoadXml function of XMLDocument.

But that's useless anyway, because you already have an XML document (WP_XMLdoc).
You try to accomplish something which you did not tell us - and all the code you showed is so weird because you got confused by not defining your requirements...
