[orbeon-user] Combining multiple results of XPL - new thoughts.

[stephan]

Hi there,

I'm just wondering how to do that. We have an app that retrieves people from a database, then pulls deals (of that people) from another database and finally uses a webservice to retrieve exchange rates.

I have managed to write 3 XPL that return XML Files with the information needed and now need to combine them into one structured XML file to hand it over to the caller. What would be the appropriate way to do so. Thought that I had:

- Wrap all results in a common header element and use aggregate() ... as suggested before.
- Can I use document() in an XLST transformation that points to an XPL file that gets executed?
- Would the XUpdate processor be an option? Replace on tag in the "main" document with an xpath result from the others?

Sufficiently confused.
