My input message has a base64Binary “contents” field. I need to “pull it off” of the message and hand it to a C# function for processing. Can someone give me an example of the expression shape code needed to handle this “contents” field as a regular string?
It’s my intent to lift the “contents” field (as a string), pass it to the C# function, and then deal with the base64Binary conversion there.
My initial attempt (as follows) fails with an “InvalidOperationException”…
workString = xpath(inputMsg, “/*[local-name()=’submitDocument’ and namespace-uri()=’urn:mxdServices’]/*[local-name()=’contents’ and namespace-uri()=”]”);

Was the exception raised by the xpath() operation or by the code you’re calling? Have you checked that the xpath is correct and is only returning a single node (you might need to do a string() in there to ensure it)?
Other than that, it should be fairly straightforward, as your C# code can simply call Convert.FromBase64String() to convert the base64 content into a byte array.
