Using sitemap parameters in a cinclude transformation

[Björn Voigt <bv...@hs-harz.de>]

Moin Cocooners,

I want aggregate some internal pipelines. The generated file
should have a more complex structure instead of only one root element,
which the simple sitemap aggregation is providing.

I want use the cinclude mechanism, but it seems to be not able to
handle parameters from the sitemap. Is this not possible with cinclude?

I will replace this:

       <map:match pattern="*.html">
         <map:aggregate element="site">
           <map:part src="cocoon:/menu-{0}"/>
           <map:part src="cocoon:/body-{0}"/>
         </map:aggregate>
    	<map:transform type="encodeURL"/>
	[...]
       </map:match>

with something like this:

<map:match pattern="pattern="*.html"">
   <map:generate src="aggregation.xml"/>
   <map:transform type="cinclude">
	<map:parameter name="value" value="{1}"/>
   </map:transform>
   [...]
</map:match>

<site xmlns:cinclude="http://apache.org/cocoon/include/1.0">
     <cinclude:include src="cocoon:/menu-{value}"/>
     <cinclude:include src="cocoon:/menu-{value}"/>
</site>

Thank you for helpfull ideas,

Björn Voigt

Re: Using sitemap parameters in a cinclude transformation

The cinclude transformer itself does not have the capability to pass and
fill in parameters. You should combine the cinclude with another technique
such as:

   1)  JXTemplateGenerator:(preferred way)  this uses Jexl and JXPath to
access variables, you got some standard objects you can use here such as
request/parameters and session, look for the docs in your cocoon under flow
    <map:generate type="jx" ....>
        <map:parameter name="url" value=""/>
    </map:generate>

        ->sourcefile: something like <cinclude:include
src="#{$cocoon/parameters/url}"/>

 2)   XSP: (old way) in XSP you can create your cinclude tags and use logic
to get your sitemapparameter (parameters.getParameter(..))
    <map:generate type="serverpages"...>
        <map:parameter name="" value=""/>
    </map:generator>

    ->sourcefile
    <xsp:logic>
        String url = paramters.getParameter("...");
    </xsp:logic>
        create your element and add an attribute
    <cinclude:include>
        <xsp:attribute name="src"><xsp:expr>url</xsp:expr></xsp:attribute>
    </cinclude:include>

thus replace your normal xml generator with one of the previous generators
and adjust your source file.

Kind Regards,
Jan
