Sending a resulting XML document to another pipeline

[Goetzmann Bertrand]

Hello to the community,
 
Another question : in my sitemap.xmap I have a pipeline containing a matcher 
that generates an XML document (by the XML serializer) ; and I would want a way 
to send this result to another matcher that will take this document by a 
generator to do another transformation.
It's seems I need to use the stream generator, but I will approciate an example 
or indication.
 
Thank you !
