Subject Re: Can I use a message translator with an xpath expression?
Date Thu, 07 May 2009 10:00:27 GMT

What do you expect as output from the xpath expression?
Its a NodeList if for instance the xml contains multiple students.

Can you post an example? What you send IN and what your expect as OUT ?
