In the cocoon environment, XSP provides a great
way of address problems that don't fit into
the paradigm of an existing generator.
However, XSP can only be used at the first
step in a pipeline.
I find myself writing lots of custom transformers
to address issues that don't fit into any
of the existing standard generators.
Would there be a way to write an XSP Transformer?
How about we call this "XST" for now. Some of
it's characteristics would be:
o A conventional transformer class would exits.
o In a pipeline, one would specify the above
transformer and a particular xst file.
o The xst file would be compile automatically
when needed.
o A basic internal design would simply allow
hooks to the various SAX events (i.e. start and
end of element and document).
o Output events could be nicely written as in xsp
like "<yada><xst:expr>string</xst:expr></yada>"
o Perhaps a more a more interesting internal
model would come with a stack to facilitate
more complex processing.
