Hello,

I'm using xalan-j 2.6, and trying to invoke a transformation using XSL
file that contains the function "empty", but I'm getting the below
exception, I think the empty function is a valid XPath function, and
XML Spy can translate docuements using this XSL file without any
problems.

Is it a bug in xalan? I tried 2.7 but I got the same exception.

Any idea what's happening?

Sorry, couldn't resist.

Do you mean that you think empty is a standard function, or that you
have defined a function called "empty" in the XSLT file? If the former,
why do you think that? If the latter, Xalan does not support XSLT 2.0 as
yet, which I believe is necessary to define a function without
non-standard extensions.
