RE: Complex transformations using Jade

["joseph, Gershon" <Gershon_joseph@xxxxxxxxxxxxx>]

Yes, please post the stylesheet. I'll try to use it to write my own
transformation stylesheet. If I can get it to work, I'll publish the result,
because it's a semi-generic RTF to DocBook transformation, which I'm sure
many people will find useful.

   While I do, personally, believe that the DSSSL transformation
language would serve as a better base for implementing these types of
transformations, Jade's non-standard SGML transformation backend works
quite nicely for this sort of thing.  Just look at what Norm Walsh has
done with it to create the Docbook->HTML style sheet.
   I'm not sure I completely understand your concern about elements
inside other elements, but I'm relatively sure you can do it with this
method.
   If you'd like, I could post a stylesheet (with example input and
output documents) that I created to transform a custom DTD into HTML
(which is just another SGML DTD, really).  It probably shows most of
the constructs that you'd use, as well as a few neat tricks to make
some parts of the process a little easier (such as an interesting
"template" mechanism for transforming certain parts).  Let me know.
