[cl-xmpp-devel] Trouble with escapes

Mon Jan 23 01:08:25 UTC 2006

This is probably a question for cxml, but I thought I'd check with you
(Erik) first.  CXML appears to have trouble parsing escaped
characters.  For example, when calling read-stanza on a stream that
contains &apos, I get the stacktrace below.  It also happens when I
send messages containing single quotes, double quotes, and ampersands.

I can see from the stacktrace that cxml is trying to process the
', but something is throwing it off.

Here is the debug output from cl-xmpp (just to show how far the parser gets):
<message from='awt at shiva.guruza.com/Psi' to='gernika at shiva.guruza.com'
type='chat' id='ac28a'>
<body>hey man what is up &apos

Any ideas?

The value NIL is not of type CXML::STREAM-NAME.
   [Condition of type TYPE-ERROR]
