Dynamically transform a generators output

["Shaw, Chris" <Ch...@ecb.int>]

Hi

I have the following scenario...

The user choses, on an HTML Form, for which format they want the output
(e.g. PDF, XML, HTML, etc)...and the parameter called 'format' gets set as
to whatever they chose
...eg format=pdf.

A generator is called which executes a database query and returns all the
data as XML...

The problem?
I want to use a different transformer depending on what the 'format'
parameter was set to....

I searched the docs and mailing archives already....but couldn't find the
answer....

This is what I have so far.....but the variable 'format' seems to get lost
along the way.
   <map:pipeline>
        <map:match pattern="*-find">
            <map:generate type="find-action"/>
            <map:transform type="xslt" src="stylesheets/{format}.xsl"/>
            <map:serialize/>
        </map:match>
    </map:pipeline>

I did also discover from the docs the following tag:
   <map:parameter name="use-request-parameters" value="true"/>
but this states that the parameters are "available in the XSLT stylesheet" -
and I need it before then (also I couldn't get it to work in the XSLT
stylesheet anyway).

Can someone point me in the right direction to overcoming this...

Many TIA

Chris

Hi Chris,

Look at request selector usage in cocoon's default sitemap. Also, have a look at the very good tutorial http://www.cocooncenter.de/cc/documents/resources/request-params/requestselector.html

Best regards
