Hi Geert Jorsten,
thank you for your detailed explanation. But now I'm a little but
confused ;-) I'll try to set up an action but at the moment struggling
with some .tmp files issues. So therefore I would also like to try your
why as it sound very good but on the other way a little bit confusing.
Hopefully I can ask you few questions to this to fully understand. I
know how transformer work ad at the end i only need and xml file
containing the information in the way the transformer needs for writing.
So far so good _but: how can I receive the directory and files as well
as all subdirectory and subfiles within the zip file I want to extract?_
And the second question will be, how I have to set this instruction in
the xml file, that contains the save information. cocoon wiki only tells me
<save:file
src="mySourceUrl"
target="myTargetFileName"
xmlns:save="http://daidalos.nl/cocoon/save/1.0"; />
I_n what kind of why I have to set the src attribute, as at the end it has to
read the files and folder within the zip file?_
Perhaps you can give me another hint ;-) Hopefully, H.

Hi,
It was a rather short and quick answer, but yes, depending on the
component that extracts the files and writes them, it is in principle
possible to extract all types of files. SourceWriting component however
uses XML/DOM as intermediate, so that component is unuseable as it is.
(At least how it was around versions 2.1.4 - 2.1.6..)
The SaveFiles transformer however is exactly written for this task. It
doesn't cache anything, it redirect an inputstream to an outputstream
internally and is therefore capable of handling binary. Only the outcome
(fail or success) is passed to cocoon as xml. More about it on wiki:
http://wiki.apache.org/cocoon/SaveFilesTransformer
My zipsource produces on long xml with the full contents. One xsl pass
converts this to savefiles instruction sheet, just a long list of
save:file elements with a src and a target attribute. These can be
processed in a single pass with the transformer. The end result of this
transform can be used to produce a fail/success report.
One final note on Cocoon Actions, the alternative on which Joerg
Heinicke responded:
be aware of the moment on which actions are executed. Regardless of
where they are called within a request-chain, they are always executed
_before_ the actual processing in a pipeline. This is only important if
you intend to process the files with the same request that also extracts
the files. It might be very useful, but can be a bottle-neck just as
easily.
Kind regards,
Geert

Subject: Re: unpack/unizp a complete zip file?
Thank you for your answer ,
but I'm a little bit confused, would this methode also work,
if the zip file contains not only xml-files but also
pictures. For example ein Open Document Writer file. I would
like to have a methode where I can unpack the full odt files.
Best regards,
H.

Hi,
I extended the ZipSource component to accept zip-protocol patterns
without the addition of special files. But the Source is
supposed to
produce content and you cannot produce the literal zip
contents, so I
chose to produce a dir-listing of the zip. I use that to
generate new
zip-url's that exhaustingly point to all files inside zip.
Processing
that list with a component like savefiles or writesource
should result
in extraction of a complete zip.
HTH,

Subject: unpack/unizp a complete zip file?
Hi,
how can I unzip a zip file with an sitemap instruction. I
have access
to a special file with zip:/file.zip!/file.xml but I would like to
have an instruction to unzip the complete file.zip. Is
there a easy
way to do so in Cocoon 2.1.? I did't found a answer on
wiki as well
as apache cocoon homepage.
Regards,
Holger
