Subject RE: Writing a DigesterTransformer
Date Fri, 23 Aug 2002 05:52:21 GMT
Hi Per,

As far as I know it should work under 2.0.3. We are using a nightly build of
Cocoon so I am not really sure. I'll probably have a first version finished
today which will be donated to Cocoon. It can be configured to use a command
class to process the resulting Java structure, .

Thanks for the feedback ;-)

This is cool! Do you know of any dependencies on 2.1 or should this work
I try under 2.0.3?
