Hi,

I have a query on XPath:

Is it possible to add extra functions to XPath 1.0 specifications, such that Xalan could call those functions actually implemented by me in my application, without using XSL ?

For example: If I have some expression "cube('id('some-id')), where id() is XPath function and

cube() is mine.

Please let me know how to do it.

You can look at the ExternalFunction sample.
