Aplly transformation to a xml post data
hello all,
I handle a upload request send by cocoon forms with flowscript :
var uploadWidget = form.lookupWidget("upload");
var stream = uploadWidget.getValue().getInputStream();
I'd like to transform the upload stream (which is XML) via a pipeline :
cocoon.processPipelineTo(
'uri',
stream,
??);
what kind of generator i must use ?
<map:match pattern="uri">
<map:generator type ="/*????????*/"/>
<map:transform src="tranform.xsl"/>
<map:serialize type="xml"/>
</map:match>
thanks,
Sébastien.

Well -- that's the part I'm working on right now, but I have a
working stub.
( See other thread about realpath: I want to move the file to a work
area,
display styled results and as whether to move to published area,
after
checking for file-exists, login and session attributes, and some
other things.)
For the stub, so far, the pipeline is:
<map:pipeline>
<map:match pattern="xml-upload-process">
<map:call function="upload" >
<!-- <map:parameter name="temp_dir" value="/tmp" /> -->
<map:parameter name="temp_dir" value="{contextpath:./
work}" />
</map:call>
</map:match>
</map:pipeline>
( I just changed temp/work destination from /tmp to {contextpath:./
work} which will
resolve to ./work directory under my mounted sitemap directory. )
And the flowscript stub (after removing some site specific parameter
processing) is:
importClass( Packages.org.apache.commons.transaction.util.FileHelper );
function upload() {
var docsrc = cocoon.request.getParameter( "pubxml");
// make a copy of uploaded file to tmp ...
if ( FileHelper.fileExists( docsrc ) ) {
var doc = java.io.File( docsrc );
FileHelper.copy( doc, java.io.File
( cocoon.parameters.temp_dir, doc.getName() ));
}
cocoon.sendPage( 'xml-upload-doc' , {} );
}
Parameter pubxml ( which is the name of the file input in the form,
and is also used as the partname in upload:/pubxml ) gets the pathname
of the file uploaded to cocoon's temporary upload directory.
The files get removed from that directory at the completion of the
pipeline,
so it is copied to another location. The pipeline in 'xml-upload-doc' is
using upload:/pubxml as the source -- it still works in the sub-
pipeline,
but at one point I inserted an interim sendPageAndWait call, but the
uploaded file disappears before the continuation is resumed so that
breaks the xml-upload-doc pipeline. Any processing after resumption of
a continuation would have to use the copied file as the source.
The display of the uploaded xml would work without the flowscript --
you would just need to call xml-upload-doc pipeline from the form
action,
but in that case, the file would disappear after it was displayed.
But perhaps a SourceWriter could be inserted in the middle of the
pipeline
to write the uploaded file somewhere.

Could you send us an example of your flowscript ?
The one which call the pipeline xml-upload-xml for instance.
Thanx a lot !

I'm not using the uploadWidget -- I just have this in my form:
<input type="file" name="pubxml" />
My form action is calling a flowscript, which then calls one
of these pipelines, using the upload://partname internal protocol:
<!-- display upload as xml -->
<map:pipeline>
<map:match pattern="xml-upload-xml">
<map:generate src="upload://pubxml" />
<map:serialize type="xml" />
</map:match>
</map:pipeline>
<!-- display upload styled as html -->
<map:pipeline>
<map:match pattern="xml-upload-doc">
<map:generate src="upload://pubxml" />
<map:transform src="xsl/document.xsl" />
<map:serialize type="html" />
</map:match>
</map:pipeline>

Thanx,
i've found this page http://cocoon.apache.org/2.1/861.daisy.html which
describe what you 'v mentioned.

You can use the normal resource generator, and a 'module:' source URI to
fetch the content from a flow attribute:
cocoon.processPipelineTo(
'uri',
stream,
{stream:stream});
<map:generator src="module:flow-attr:stream" />
