[xsl] Xslt transformation of an xslt transform

[Andy Bailey <andy@xxxxxxxxxxxxxxxxx>]

I have a tricky question thats been bugging me for a while. I am
using forrest to do transforms for my company's website, but am
interested in offloading the xslt processing to the browser (when it
is able to do it). However the xslt processing is in a pipeline, so
what I am really interested in doing is combining several xslt
transforms in one. I havent found any information on Internet.

My pipeline are like:

Xml (any format) > Docbook xml > i18n transform > xhtml

Although it seems to be possible it doesnt look like a trivial task.

Has anyone implemented this?

Can you modify the DOM of the xslt parse tree of a transformer directly
before it does the transformation? (a plugin or callback perhaps)

Or I suppose you could do it outside of the transformer, write a
stylesheet that transforms the xslt stylesheet for xml into an xslt
stylesheet for xslt, repeat for each xslt apart from the first, then
chain the results together to get the single xslt stylesheet. Is this
feasible? (I can see functions being a problem but if its just
standard xslt it just might work)

Another idea: is it possible to send a pipeline of xslt transforms for
the browser to perform (I imagine not and also it would slow the
browser down)?

Is there any active development going on in this area?

Cocoon goes to great lengths to cache intermediate results of
transforms, to speed the pipeline up but my hunch is that this would
speed the pipeline up a lot more (if its possible).

Thanks in advance,

Andy Bailey
