Thanks Charles, I need to have a play with it to see which is going to be the easiest to maintain.

Either way the template is going to be massive. It would be nice if there was some way of being able to break it down into a number of smaller documents, particularly since some of the 'if' statements are inserting some massive sections.

This is easily done by delegating some of the logic to separate templates, which are fired by selecting the apply-templates instruction (your pull shifts to a push), or more rigidly by simply using a named template and the call-template instruction (so applying a template by calling it by name instead of selecting a node which matches it).


One characteristic of "push" is that the logic is distributed among a set of templates, whereas with "pull" it is often (or may as well be) in a single template. This also accounts for the flexibility of "push" in situations where the structure of the input is highly variable (since you can select whatever nodes are there and the proper templates will be found to match them).

Cheers,
Wendell
