[C3] Passing parameters from sitemap to generator
Hi all,
recently I have been in the situation for which I need to parametrize an
XML file of my application; I thought there was a simpler way but I
ended up by using an additional XSLT transformation step (since the
XSLTTransformer can accep parameters from the pipeline).
With C2.1 I used to put in place the JXGenerator [1] (or JXTransformer
[2] depending on the case): this saved me, in many cases, from an
additional transformation step in the pipeline.
Even though it is true that everything you could do with JXGenerator can
always be done with XMLGenerator + XSLTTransformer, do you think that
such component can be a "nice to have" in C3?
Cheers.

This was exactly my scenario: I am writing a (kind of) JCR generator
that reads from a Jackrabbit repository depending on (sub) request path.

This could also be the case.

Hi,
Maybe the Generator is sufficient?
To pass parameters from the sitemap is not it is not a big deal.
What sort of parameters do you want? Parts of the path?
controlStuff{tat}/{tit}/{tot}
request parameters?
Kind regards,
Jos

Hi,
JXGenerator is really useful, its a must have for me.

After taking a closer look to cocoon-stringtemplate, I ended up by doing
some adjustments to the previous implementation, updating to latest
StringTemplate available to maven and adding, besides the
StringTemplateGenerator, a StringTemplateTransformer.
I have also updated cocoon-sample so that it should be straightforward
to check these two components running.
In this way, we (well, at least I) have something that should cover the
principal use cases of JX* or VelocityGenerator.
Cheers.

How long should it be to add sitemap parameter handling there?

As far as the "sitemap parameter handling" part is viable, the
VelocityGenerator could be fine.
Cheers.

So far there is only the StringTemplateGenerator component, that
dynamically generates XML based on a template.
There are also no 'build-in' objects like request, session, etc. which
were supported by the JXGenerator or the VelocityGenerator in Cocoon 2.x
I have no strong opinion on what should be migrated to C3 as long as it
goes into a new module or the cocoon-optional module ;-)
I suggest that you choose that technology that fits your requirements
and your time constraints (VelocityGenerator should be rather straight
forward, migrating JX* is definitly more-timeconsuming) best.
