[cxml-devel] READ-TOKEN-3 bad data from CL+SSL stream? - cxml-devel - mailman3.common-lisp.net

14 Nov 2005


      Using CVS cl-xmpp, cl+ssl and the latest cxml release I get the
following error when trying to parse xml from the ssl stream:
* (defparameter *c* (xmpp:connect-tls :hostname "talk.google.com"

Perhaps I'm missing something and have missed a step in how to convert
my stream to an SSL stream.  Here's the code:
(setf (server-stream connection)
    (cl+ssl:make-ssl-client-stream (server-stream connection))
Then I proceed to write and read to the stream as if it were an
(unsigned-byte 8) stream just like the original one.  Is this correct?
What's that Unknown character #\Etb about?  I would've expected at
this point to get <?xml version='1.0' ?> from the server.
Any pointers would be helpful.
Thanks,
Erik.
