thanks Ricardo Trindade -----Original Message----- From: Paul Pattison [mailto:[EMAIL PROTECTED]] Sent: sexta-feira, 19 de Abril de 2002 18:43 To: Cocoon Mailing List Subject: Separation of Concerns (presentation elements) Hi everyone, I had a brief stint where I used Jakarta's Turbine project. One of the things that I really liked about it was that it divided a page's presentation elements into a bunch of separate files (navigation,content,layout,etc). I guess it didn't really sink in that I could do all that with Cocoon until a few days ago when I read Andreas Hartmann's 'Creating a Navigation Menu' tutorial. I thought this was an excellent tutorial! The one thing that I wanted to change was the fact that in that tutorial, he uses a cryptic url pattern to give the sitemap parameters for what section and style a page should have. I would prefer to use an ordinary convention (ie just *.html). With Turbine, a 'layout' for example was set by calling the 'setLayoutTemplate("/PrintableLayout.vm")' method at the top of a page. I really liked how the layout was defined as a part of the page. So for my Cocoon page I wanted to have something like this: <page> <layout>homepage.xsl</layout> <style>simple-page2html.xsl</style> <content>foo</content> </page> A 'layout' describes the structure of the page. This means where the content, navigation, header and footer go. A 'style' describes the look of the content. But I couldn't figure out how to get these values to the sitemap so that it could chose the appropriate .xsl files. Then today I took a stab at understanding Actions better and it seems to me like this is the approach I need. I should create an action that would open my page read the values of the tags requested and return their values. I figured I could create this generic enough that it could be used to read any tag values in any specified xml document and be used for other purposes. So here's what my sitemap would include: <map:match pattern="*.html"> <map:act type="param-fetcher"> <!-- page to get values from --> <map:parameter name="filename" value="{1}.xml"/> <!-- tags to get values from --> <map:parameter name="tags" value="style,layout"/> <map:generate type="file" src="documents/{1}.xml"/> <map:transform src="stylesheets/{style}-html.xsl"/> <map:transform src="layouts/{layout}.xsl"/> <map:serialize type="html"/> </map:act> </map:match> Before I wrote the Action I wanted to see what people thought of this approach. Is it a good idea? Is it something that would be helpful to have as an included Action? Is there a better way of doing it? Wow, this was a long email. If you made it through the whole thing and have some feedback for me that would be GREAT!! Thanks in advance.
