Xalan-c, bdbxml and the document() function

[Ivan Bogouchev / Иван Богушев]

Hi all,

I am considering the integration of Xalan-c and sleepycat's berkley dbxml.

It is no problem to extract a document from the db, and then reparse/transform it with Xalan (there is also the possibility to get directly a Xerces-c DOM tree from the db).
But I need to be able to load new documents coming from the db from within my stylesheets.

So I guess one solution would be to write an extension function for the XalanTransformer that loads a document from the db (or even executes a XQuery), but I was wandering if it is possible to extend the existing document() function, in order to be able to do document('bdbxml://container/document').

And now the question: is it possible to extend the document() function in such a way and if yes can someone give me some hints on where to start?
