[xmlblaster-devel] python xml-rpc client, key with embedded ampersand

["Brad Clements" <bkc at murkworks.com>]

I am running xmlBlaster version 1.0.6 Xmas 2005-08-10

I'm using pyblaster, sending a key that contains an element, whose 
element text includes an amper sign.

xml-blaster receives the xml-rpc request, but seems that somewhere, the 
escaping of the amper is not handled properly.

I added a print statement to pyblaster.py, in XMLBlasterClient.publish()

XMLKEY = '<key contentMime="text/xml"><sfi type="instance">
        <messageprocessor type="instance">
            <dn>cn=brad.clements,o=sfiusa,dc=public,dc=strader-ferris,dc=com</dn>
            <organization>Dew Engineering &amp; Development In</organization>
            <admin_message_type>party_username_signup</admin_message_type>
            <message_type>admin_email</message_type>
            <recipient_dn>cn=james.gendron,o=dew,dc=public,dc=strader-ferris,dc=com</recipient_dn>
        </messageprocessor>
    </sfi></key>'


You'll note that in the publish call, the amper in the <organization> 
element is escaped.

However I get an xml-rpc error back from the publish call
(in this example, the key is slightly different, but it's the same basic 
problem)

          Module pyBlaster.pyBlaster, line 213, in publish

                    <recipient_dn>cn=Janet.Collins,o=dew,dc=public,dc=strader-ferris,dc=com</recipient_dn>
                </messageprocessor>
            </sfi>\n 
        </key>">


Note that the returned error text does not show that the amp is escaped..

Etherreal shows that the xml text is all escaped.

        </param>

This looks like a problem in the xml-rpc server component of xml-blaster. 
Is there  a fix?
