Bill , I have tested your scenario with the following mediator configuration and the message. It worked.
Mediator configuration <filter xmlns="http://ws.apache.org/ns/synapse" xpath="boolean(//m:GetQuote/m:symbol/@sessionID)" xmlns:m=" http://www.webserviceX.NET/"> <log level="custom"> <property name="sessID" expression="//m:GetQuote/m:symbol/@sessionID" xmlns:m=" http://www.webserviceX.NET/"/> </log> </filter> Message <m:GetQuote xmlns:m="http://www.webserviceX.NET/"> <m:symbol *sessionID="one"*>IBM</m:symbol> </m:GetQuote> Out put *sessID = one* Thanks Indika
