source writing transformer exception

[Reinhard Haller <re...@interactive-net.de>]

Hi,

I've set up a pipeline to sanitize a bunch of xml files.

The following matcher reads an xml file and stores the
changed file with the source writing transformer in the same
place.

<map:match pattern="**/*.*-transform">
   <map:generate src="{1}/{2}.xml" />
   <map:transform src="xslt/update/{3}.xslt" />
   <map:transform src="xslt/rssstore.xslt" >
      <map:parameter name="path" value="news" />
   </map:transform>
   <map:transform type="write-source-utf-8" >
      <map:parameter name="serializer" value="xml-utf-8"/>
   </map:transform>
   <map:serialize type="xml-utf-8" />			
</map:match>

Doing so, the pipeline stops with the exception:

"Could not process your document."

Storing the file to another place works. Is there a way to solve
the problem?

Thanks
Reinhard

When the source is an XML file, it's open and locked during pipeline 
processing. So you cannot write to it in the same pipeline (it's like 
reading from a text file one line at a time and trying to write that 
line back at the same time).

It worked for me if I put the source file inside an aggregate (I 
actually needed it there).
If you do not want to use aggregate, you can try using cocoon: protocol, 
but I am not sure if it will work.
Basically the idea is to isolate the source in a separate "request".
