This is the problem that "tunnel parameters" in XSLT 2.0 were designed to solve.

I used 2 or 3 # global parameters to manage things like the where to write # the file, how to format, etc. # # This process has been working fine because I have had a # single document that I want to process. Now I need to process # a group of documents into the help format. These documents # have sections that should cross-reference each, so processing # individually is not an option I want to look at. # # My problem is that each document may have a slightly # different combination of control parameters. I've started # converting my process over to use a configuration file that # lists the objects to process and their individual parameters. # # In making this conversion I've noticed a major programming # change. Where I could just rely upon the parameters being # available in the old model, I now have to pass these # parameters between templates directly. The problem is that I # don't have a template for every level in my document. What # happens is if I do not explicitly pass a parameter through a # template (called in document order, not by name or anything # else) then that template doesn't have access to the parameters value. # # What I would at least like to do is convert all my # <xsl:apply-templates/> to something like this: # # <xsl:apply-templates> # <xsl:with-param name="dir" select="$dir"/> # </xsl:apply-templates> # # If I have a structure like: # Body # Sect # Div # head # Listing # head # # I used to get away with not having to have explicit templates # for Div and Listing to have a template for head work just fine. # # Any ideas on how to re-arrange things so I don't have to add # all these "default like" templates? # # I would really like the apply-templates to create its own # default template setup where not only do modes get # automatically added, how about picking up the set of # parameters as well? # # Barring that from working, it would be nice to somehow use # the <xsl:include> somewhere other than the top of a stylesheet and use # document() to specify the include as well as the parameters # that should be used for that particular document. # # Anyone got another idea for how to tackle this? My current # design is going to be very buggy, depending upon how stable # the DTD remains in the future. # # ..dan # -------------------------------------------------------------- # ------------- # Danny Vint # http://www.dvint.com # # # # # # XSL-List info and archive: http://www.mulberrytech.com/xsl/xsl-list # #
