Subject RE: XSP + Dynamic XML generator ??
Date Tue, 07 May 2002 08:29:00 GMT
Isn't the xsl-dynamic page that you need?  The sample can be found at 
http://localhost:8080/cocoon/sub/xsl-dynamic
The transformer of the main pipeline calls a different pipeline where an 
XSP page  generates the transformations.  To my opinion XSP can be used as 
a transformer this way, no?

    <!-- Dynamic XSL -->
    <map:match pattern="xsl-dynamic-source">
     <map:generate type="serverpages" src="stylesheets/simple-page2html.xsp"/>
     <map:serialize type="xml"/>
    </map:match>
    <map:match pattern="xsl-dynamic">
     <map:generate src="docs/simple.xml"/>
     <map:transform src="cocoon:/xsl-dynamic-source"/>
     <map:serialize/>
    </map:match>
