Subject Re: Is there any tool or method to debug the pipeline?
Date Mon, 12 Apr 2004 08:09:08 GMT
How come no-one has mentioned views? Set up a view in your sitemap, and 
view your page with a URL like:
http://localhost:8888/yourpage?cocoon-view=yourview to see the XML at a 
certain point in your pipeline.
