Need a few pointers with XPL Pipeline please

Hi Alex

Thank you for your reply. I have managed to make some progress since posting and I have some questions based on the attached reference code.

In my 'analyse-preprocess' XPL I am trying to execute the external grep.exe with parameters resulting from an xmldb-query. I have debug turned on but can not find any visual reference in the log that tells me if any part of this XPL is working. In the log there are no errors and I can see entry/exit from the ProcessorService. I have also tried adding debug attributes to the input/output elements but these do not show up.

The install is as per the orginal WAR file so I am assuming (having looked at the eXist http://localhost:8080/orbeon/exist/rest/db/orbeon/...) is configured default as guest/guest?

Thanks, Ian.

I would suggest you look at the code of existing examples, for instance the "XForms translate" example calls an XPL from XForms:

https://github.com/orbeon/orbeon-forms/tree/master/src/resources/apps/xforms-translate

This will give you an idea of how you make such a request from XForms, hook the XPL through the page flow to run when a certain HTTP request comes in, and run processors in the XPL. Then I'd recommend you go through the XPL
doc:

http://wiki.orbeon.com/forms/doc/developer-guide/xml-pipeline-language-xpl

After this, I hope you'll be in a better place to start coding that pipeline, and of course, when doing so, you'll let us know if you have any question; at that point, your question are likely to be more specific, and we should be able to provide more useful answers.

Alex
