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?
Oh that is easy. Use the Cocoon "Directory generator".
http://cocoon.apache.org/2.1/userdocs/generators/directory-generator.html
In addition to these docs you can see an example of it used in Forrest
in the photoGallery plugin.
