Hi Wendell,

I think I would use p:wrap-sequence with multiple pipe bindings on its
input. You are aware that you can put multiple p:pipe elements inside a
p:input?

Kind regards,
Geert

Onderwerp: Aggregating results: hints wanted

Hi,

Not having quite the time to give to XProc as I'd like, I'm fumbling
along and managing mostly, but occasionally need some advice. (Honestly,
I feel the way many XSLT newbies must. I get the general idea, but the
core concepts -- to say nothing of specific aspects of its design -- are
just not embedded well enough into my brain for me to have much
confidence that I'm thinking about it right.)

My current problem is as follows: I have a pipeline of XSLT
transformations (it's actually twelve steps long), which works well, but
I would also like to intervene at points with Schematron validation. I
get how I can capture the results of a validation (its 'report' port)
while the input, having been validated, can go on to the next step in
the pipeline.

However, I'd like to do this with several discrete Schematrons operating
on the results of several of my XSLT steps, but bundle all their reports
together into a single result (which I might then process with more XSLT).

(I know this may seem odd, but the pipeline is a sort of upconversion
from arbitrary inputs, and I'm trying to detect problems in the input at
the time when they are easiest to detect.)

I can see how I could use p:pack to pack two of them together, but what
if I have more than two?

Do I have to use p:pack repeatedly? (And perhaps p:unwrap to unwrap the
wrappers that get introduced every time I pack?)

I imagine there must be a more graceful way, and would be grateful for
any advice or corrections.

Cheers,
Wendell
