RE: [xsl] Trax and how to pass parameters to

["Michael Kay" <mhk@xxxxxxxxx>]

You can't. There's a recent thread on the Saxon forum about this:

http://sourceforge.net/forum/forum.php?thread_id=1027851&forum_id=94027

The answer is, instead of generating your transformation as an XMLFilter,
use a SAXTransformerHandler. You can still pipeline transformations, and in
many ways the code is easier.

Other options:

(a) In Saxon 7.x, you can cast the XMLFilter to a net.sf.saxon.Filter, which
provides access to getTransformer().setParameter()

(b) Pass the parameter values down the pipeline so they arrive as part of
the source document

(c) Write a URIResolver to deliver the parameter values in response to a
call on document()

# Subject: [xsl] Trax and how to pass parameters to
# 
# Can anyone tell me how to pass parameters to Trax (javax) if you are
# using a filter? I have included my sample code below.
# 
# Note that I have actually compiled one stylesheet and passed a parameter
# to it, but I can't actually use the passed parameters in my chain below.
# 
# I asked this question on the Sun mailing list with no responses. It
# seems using XMLFilter is still kind of a black art!

# Thanks

#      // If one success, assume all will succeed.
