Re: InflatedFileGenerator
Hi Jean, We use the OpenOffice format a fair bit here for other projects. I did write a simple generator to extract the 'content.xml' from the .sxw file but it was a bit of a kludgey hack as my java skills are still a bit infantile! I'd be interested in utilising your offering if that's possible.

RE: InflatedFileGenerator
You can read zipped content with the regular FileGenerator, using the jar: protocol.

Re: InflatedFileGenerator
I didn't know the FileGenerator zipped capabilities ...
Here it is my source. It's pretty simple. It inherits from the
FileGenerator.
You have to give 4 parameters :
* src : src archive path
* directory : dir where you want to store the unzipped content
* file : file to extract
* newfile : new filename
pipeline
map:match pattern=process-training-ooo-*
map:generate type=inflated src=training/{1}.sxw
map:parameter name=directory value=ooo/
map:parameter name=file value=content.xml/
map:parameter name=newfile value={1}.xml/
/map:generate
map:transform src=stylesheets/tranform.xsl/
map:serialize type=xml/
/map:match
/pipeline
Of course, don't forget :
map:generators
...
map:generator label=content logger=sitemap.generator.inflated
name=inflated pool-grow=4 pool-max=32 pool-min=8
src=org.apache.cocoon.generation.InflatedFileGenerator/
...
/map:generators
Hope that helps.

It's useful if you want to use, for example, standart OpenOffice.org
format .sxw instead of flat xml.
Of course you can use it with .zip format.
Usage example :
...
map:match pattern=process-ooo
map:generate
