Okay, my real question is how to aggregate unknown number of documents?
Here is my case (using Forrest 0.6): In my xdocs folder I have a folder called
tasks. It contains a collection of XML formatted files, where each file
describes a single task. I like to aggregate them all in one single document
"Task Summary". Here is what I have in site.xml file:
--- site.xml ---
<about label="MyProd" tab="home">
<index label="Welcome" href="index.html" description="Welcome to MyProd"/>
<tasksummary label="Task Summary" href="tasksummary.html"/>
</about>
Here the tasksummary.html points to a tasksummary.xml pipeline defined in
sitemap.xmap (It took me a significant time to figure out that a pipeline is
matched by its "pattern" instead of sort of ID)
<map:pipeline>
<map:match pattern="teamtask2section">
<map:generate src="{project:content.xdocs}/tasks/B001.teamtask"
/>
<map:transform
src="{project:resources.stylesheets}/teamtask2sec.xsl" />
<map:serialize type="xml"/>
</map:match>
</map:pipeline>
<map:pipeline>
<map:match pattern="tasksummary.xml">
<map:aggregate element="document">
<map:part src="{project:content.xdocs}/task_header.xml"
element="header"/>
<map:part src="cocoon:/teamtask2section"
element="body"/>
<map:part src="{project:content.xdocs}/footer.xml"
element="footer"/>
</map:aggregate>
<map:serialize type="xml"/>
</map:match>
</map:pipeline>
where:
task_header.xml is a generic header file.
footer.xml is a generic footer XML file
The real problem is that in the teamtask2section pipeline I can specify only
one task file B001.teamtask. And I have multiple: B002, B003 and so on. I tried
wildcards such as :
<map:generate src="{project:content.xdocs}/tasks/*.teamtask" />
But it does not work. So how do I aggregate unknown number of XML files located
in subdirectory of xdocs?
Thanks
Stefan

http://cocoon.apache.org/2.1/userdocs/concepts/sitemap.html#Aggregating
http://cocoon.apache.org/2.1/userdocs/concepts/sitemap.html#Protocols
There is an example in the Forrest core, but perhaps we should
put a very basic example in the "forrest seed" site.
You have not told us which version of forrest you are using.
For the current trunk (i.e. 0.7-dev) see webapp/sitemap.xmap
around line 490 and follow the aggregation where it gets its
parts from other sitemap matches using the "cocoon:" protocol.

Aggregation is done in the sitemap.xmap ... that is nothing
to do with site.xml ... We need an FAQ to reduce the
confusion caused by the name site.xml
