As I said on channel (answer repeated here for posterity.) You use a
VIEW. VIEWs are collections of templates that can be referred to as a
whole. Thus I can switch my whole look by using the template stored in
$a rather than the one stored in $b [1].
For example, with my tt & xpath stuff I have three sections.
- The xml file that has the data in it. This data is organised in some
arbitrary format that may or may not have anything to do with the order
it's displayed in.
- The template file that pulls out the data with XPath. This template
file may make use of several plug-ins that contain the application
logic, uses IF and other stuctures, etc., etc. The template file
actually then outputs the code using:
- A self recursing view to render the xml into some particular format
(e.g. various forms of html, wap, etc) You have multiple views
enabling you to have multiple outputs.
That's the concept, anyway.
Later.
Mark.
[1] well, actually the one stored in the template stash as 'a' rather than
the one stored in the template stash as 'b', but you get the idea.
