Hello,
I have successfully configured and used Cocoon 2.0.3 on Linux to generate HTML and PDF
files on the
fly from XML source files. I've used primarily DocBook source, but I have a few other
types of
source files.
Part of what I want to do is generate complex documents from multiple source
locations. The DocBook
source files contain tags which are used by external programs (in this case RefDB) to
generate
information for the final document. While part of this process is the application of
stylesheets,
part of it is the execution of a separate client program which retrieves the
information from a
database.
My question is how can I run an external program/script and have the final output be
what is sent to
the Transformer for display? I'm guessing I'm missing something really obvious
because no one else
seems to ask this question. My initial observation was that I would need to write a
Generator to do
the work I need done by the RefDB client application. My second observation was I
might be able to
use Jython or JavaScript to execute the program for me using the ScriptGenerator.
For the case of JavaScript, I think I'm limited in its ability to access the server
OS. Jython
should be able to do the trick, but it seems a little kludgy to write a script which
simply calls an
executable on the OS and forwards the XML output.
Is there an easy way to do this? Am I destined to write a Generator? I looked at
XSP, but my
initial observation was that it probably wouldn't work, but I might have missed
something here also.
Thanks,
Al
