The default generator @type is the XML file generator. So if cocoon://{1}/tree-expo-get-children
returns XML you don't need to specify a type on the generator.

Yes, I understood this point I think.
But which the of generator must I call there ? No particular type ?
It may like this ?
Because if it's supposed to work, the error I meet when I use a generator must be due to something

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

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

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

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"/>

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
