Re: Problem in designing pipelines

You should not use map:read but map:generate when you want to do further processing.    

 

              <map:match pattern="*/tree-expo-content">

                           <map:generate src="cocoon://{1}/tree-expo-get-children"/>

                           <map:transform src="exist/xsl/expotree2html.xsl"/>

                           <map:serialize type="html"/>

                     </map:match>

Subject: Problem in designing pipelines

 

Hi everybody,

 

I have a problem understanding how to write my pipelines.

 

I have a first pipeline :

 

                     <map:match pattern="*/tree-expo-get-children">

                           <map:generate type="xquery" src="exist/xq/get-children-rubriques.xq">

                                  <map:parameter name="parentid" value="{1}" />

                           </map:generate>

                           <map:transform src="exist/xsl/get-children-rubriques.xsl"/>

                           <map:serialize type="xml"/>

                     </map:match>

 

This pipeline works perfectly resulting a XML tree.

I would want to applicate another XSL to the resulting XML.

 

You will say that I just have to put another <map:transform> after the first one.

But I can't, because of a particularity :  the call to this first pipeline is iterative : the transform call this same pipeline.

 

So I thought about writing another :

 

                     <map:match pattern="*/tree-expo-content">

                           <map:read src="cocoon://{1}/tree-expo-get-children"/>

                           <map:transform src="exist/xsl/expotree2html.xsl"/>

                           <map:serialize type="html"/>

                     </map:match>

 

The problem is that when I execute this pipeline, I get the XML document resulting from the map:read but the transform is not performed.

If I put a map:generate replacing the map:read, the execution fails with an error in declaration of my XSL.

 

I don't understand how I can chain these transforms.

Which generator could work ?

 

Thanks for your help
