[cxml-devel] Escaped characters

Mon Jan 23 02:49:37 UTC 2006

I am running into an issue in which any time cxml encounters an
escaped character
such as ", &, etc. while parsing a socket stream, it throws
an error (pasted below).  I have tried parsing xml with such
characters using cxml:parse-file and have not encountered any issues. 
I've taken a look at the data going across the socket using tcpdump
and it appears to be transmitted correctly.

Here is an example of the type of element that causes the problem:

<message type="groupchat" id="ac0ca" to="20 at conference.shiva.guruza.com" >
<body>Hello"</body>
</message>

I'm using the cxml distributed in the cxml-2006-01-05 tar file with
sbcl 0.9.8 with unicode support.

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