This view extracts html snippets from a snippet rep. This way user from apache forrest can implement their own view for each document or use the default view without knowing xsl. sample for a view: <forrest:view xmlns:forrest="http://apache.org/forrest/templates/1.0" type="xhtml"> <forrest:contract name="meta"/> <forrest:hook name="container"> <forrest:hook name="branding"> <forrest:contract name="projectlogo"/> <forrest:contract name="grouplogo"/> <forrest:contract name="searchbox"/> <forrest:contract name="nav-main"/> </forrest:hook> <forrest:hook name="spacer" /> <forrest:contract name="nav"/> <forrest:contract name="content"/> </forrest:hook> <forrest:contract name="feedback"/> </forrest:view> pipe: index.html -> requested page index.xml -> content for the page index.fv -> styling information about the page (as forrest:view) Through the prepare.include.* and prepare.xhmtl.* I am calling html snippets from a rep based on index.fv. On the final stylesheet I am then creating the page like <xhtml> <head> <xsl:call-template name="getHead"/> <style type="text/css"> <xsl:call-template name="getCss"/> </style> </head> </xhtml> cheers for any suggestions salu2 > Michael Kay > http://www.saxonica.com/ > > > > > -----Original Message----- > > From: Thorsten Scherler [mailto:thorsten@xxxxxxxxxx] > > Sent: 23 March 2005 13:00 > > To: xsl-list@xxxxxxxxxxxxxxxxxxxxxx > > Subject: [xsl] dyn:evaluate question > > > > Hello list, > > > > I am trying to dynamically include a stylesheet like this: > > <xsl:variable name="request">index</xsl:variable> > > <xsl:include href="cocoon:/prepare.include.dyn:evaluate($request)"/> > > > > but the dyn:evaluate($request) -part will not get resolved. > > > > As soon I change it to > > <xsl:include href="cocoon:/prepare.include.index"/> > > I get my stylesheets. > > > > Am I using the dyn:evaluate wrong?
