Re: Can I pass a sitemap resource as a parameter to an xslt transformer?

2011-01-17 Thread Jasha Joachimsthal 
You don't need to pass it as a parameter. Just use map:aggregate with a
map:part that gets all the authors. To cache the result of the SQL query you
can use an expires pipeline with a very long expiration time.

 As far as I know this is NOT possible.

 As an alternative, you could include XML file with the authors list into
 the XML file containing the page that requires editing (or include the XML
 file containing the page into the XML file holding the authors list), before
 you use your transformer. The transformer that selects from the authors'
 node what it needs to produce the proper SQL.



 Any help much appreciated

RE: Can I pass a sitemap resource as a parameter to an xslt transformer?

2011-01-14 Thread Binkley, Peter 
I would use a regular pipeline for the authors list, with caching turned
on (so it doesn't run the query every time - check the cocoon docs for
how to control expiry etc.):

map:pipeline type=caching
map:match pattern=authors
...

And then include it from within the article.xsl using the cocoon:
protocol, which is used to address a pipeline in the sitemap:
 
xsl:variable name=authors
select=document('cocoon:/authors')/

Resources are used when you want to include the same series of
components in more than one pipeline. I don't think a resource can do
caching: that would be up to the pipelines in which it is called.
