xml based navigation structure within CI

[eluser]xwero[/eluser]
the xml file can be seen as data so you could put it in a model but i would make a plugin out of it based on the modification time of the xml file with following steps

- does the cache file exist -> no -> create cache file
- is the modification time equal to the time stored in the file name of the cache file -> no -> create file
- output cache file

To create the cache file you could use a CI view file or a template engine.

I would do it this way to prevent going through all the steps to create the navigation each time a page loads.
