Using XInclude to include other pages as chunks into an aggregated page

[Torsten Schlabach <TS...@gmx.net>]

Dear list,

I am trying to achieve this:

On the homepage of my site (publication) I want to be able to aggregate
content from several separate pages in Lenya. I want to keep them separate
for purposes of distributed editing and other resons.

This is what I have done:

I have been introducing a XInclude-Transformer so I can have an aggregatinng
page with several xi:include statements that should include other pages from
Lenya.

This is the problems / questions I have:

- Should this be done that way? Did I overlook a better way to to that.
- I have used xi:include href="cocoon:/lenya-document-view/..." to make sure
I will include an xhtml document even if the document I try to include is
not straight xhtml. For example, I have a gallery doctype in my publication
which will render a list of image names (custom XML) as a gallery in xhtml
through the existing custom doctype mechanism.

This all works fine except that I so far hard-coded all the parameters in
the href= piece. I have no idea where to look for if I want to use
variables. For example, when Live I need to use .../live/... and not
.../authoring/... .

I am open to comments and hints.

I did not post this on the Cocoon Users list because to me this is a
question of Lenya philosophy in the frist place. (Should it be done like
that or different?) I am not sure if a URL rewriting transformer could do
the trick, but even it it could, how would that interfer with the rest of
the Lenya framework?

Regards,
Torsten

xinclude and map:aggregate can be used to do the same thing. i prefer to 
use map:aggregate for clarity but would not mind to use it for one-offs.

this would probably be easier in the sitemap because you have access to 
input modules. for xsl, you would have to pass them in.

xinclude (and cinclude) are an alternate to aggregation.  Lenya
tends to use aggregation more often.  I prefer the xinclude approach
myself and use it in all our publications.

This is a limitation of xinclude.  The way we get around this is to
parameterize the href piece and have a simple transformer that does
parameter substition before invoking the xinclude transformer.  You
could also use the JX generator for this parameterization.
