How do I add an Xpath2.0 function to Xalan2.6?

[hicks]

I'm using a stylesheet that was created with a custom xslt engine which
makes use of Xpath2.0 features, specifically the exists() function.

Xalan 2.6 does not support Xpath2.0.

So I need to write a custom exists() function and register it
programatically in Java with Xalan.

I've consulted the Apache website, and their examples typically involve
creating extension functions in a custom namespace, then modifying the
stylesheet to use these functions. In my case I am not able to modify
the stylesheet.

My question is how do I provide and register an implementation of
exists() with the Xalan engine so it can process my stylesheet?

Any examples would be very useful.

Thanks for any help.
Andrew.

http://xml.apache.org/ lists various mailing lists dedicated to users
and/or developers of Apache XML software so I think your chances to find
expertise on that processor are much higher on such a dedicated list
than in this general group.
