Reading this a bit closer, if you have a base64 blob, you would need to
first decode it back into the original XML text. You can use the Xerces
Base64 class, but the decode method is very strict and will fail if there's
any whitespace, which is a pain. When I use it, I actually have to copy the
data, strip/collapse ws bytes, and then decode it.

Anyway, once you have the text, just pass the bytes into a stringstream
object on the stack and then you can use the stream constructor to build the
request.

If you need a sample, look at the SAMLPOSTProfile::accept() method. It
parses a response from base64.
