May be you can try to import a XML fragment via the document() XSL function. Calling a cocoon:/ URL, you will get the XML fragment in a variable inside your XSL. Neat and very efficient !!!

The idea sounds great and is a lot cleaner, than fiddling something in some XSL extension. I am not sure about the cachaebility: the XMLFragment specifying, which nodes to filter from the big input document, changes everytime, so Cocoon would need to parse the source file on every request (, if my understanding is right). If I'd slidely change your approach to implementing the same approach into a transformer component. This transformer component will not be cacheable, but at least the generator in front of it would be. Thanks again, Christian BTW, thanks also for the code snippet. It helps a lot, as soon as it comes to thinks like the ObjectModel, I start feeling uncomfortable. ----- Original Message ----- From: Hunsberger, Peter <mailto:Peter.Hunsberger@;stjude.org> To: '[EMAIL PROTECTED]' <mailto:'[EMAIL PROTECTED]'> Sent: Thursday, October 17, 2002 6:46 PM Subject: RE: ServerPageAction: XMLFragment reuse in XSL transformer There's probably about half a dozen ways to do this. Perhaps one of the simplest is just to create your own caching generator and use aggregation (with any other XML you may need) in the pipeline. In the generator you'll need to implement the setup method to see the objectModel, something like the following: private gunk mySessionData = null; public void setup( SourceResolver resolver, Map objectModel, String src, Parameters parms ) throws ProcessingException, SAXException, IOException { if (mySessionData == null ) { super.setup( resolver, objectModel, src, parms ); Request request = (Request)ObjectModelHelper.getRequest(objectModel); Session session = request.getSession(false); if (session != null) { // save a pointer to your session data for use in the generate method mySessionData = .... } } } Now in your generate method just pick up whatever data hangs off of "mySessionData" and away you go -----Original Message----- From: Christian Kurz [mailto:crkurz@;gmx.de] Sent: Thursday, October 17, 2002 11:26 AM To: [EMAIL PROTECTED] Subject: ServerPageAction: XMLFragment reuse in XSL transformer Hello cocoon-users, I need to generate some tiny XML elements (XMLFragment) within a ServerPageAction and I would like to use this XMLFragment later on in an XSL transformer, that is fed by an xml generator. The XMLFragment captured in the ServerPageAction is basically saying, which nodes are to be returned from the big input document. From some other message in this group I have understood, that passing objects is only possible through session or request objects, but not through sitemap variables. I don't like to use a request generator as the starting point of the pipeline, as I'd loose cacheability at a very early step in the pipeline. With a quite big xml input document, this does not seem a good idea to me. So I am currently struggling how to get a piece of XML, that is attached to a session or request object, into the xsl transformer. Has anybody tried this before e.g. using an XSL extension?
