Hi Nelson,

the XPATH and REGEX access plugins check the message content (full text 
search) only
and the SQL92 plugin checks the client property only, see the examples:

http://www.xmlblaster.org/xmlBlaster/doc/requirements/mime.plugin.access.sql92.html
http://www.xmlblaster.org/xmlBlaster/doc/requirements/mime.plugin.access.regex.html
http://www.xmlblaster.org/xmlBlaster/doc/requirements/mime.plugin.access.xpath.html

Your XPathFilter example above can't access the qos client property.

Marcel
