I need some help with routing

[eluser]JesseR[/eluser]
I have a url that currently looks like this :

http://www.domain.com/anything/anything_...YCODE.html
http://www.domain.com/anything/ITEMID.html

MY CI file for CATEGORIES is index.php/categories/getCategories/CATEGORYCODE
MY CI file for ITEMS is index.php/categories/getItem/ITEMCODE

My current website that does not use CI uses this link structure.
Can anyone advise how I can setup routing to work with the above
link structure?

There's an example in the user guide explaining almost exactly what you want.

If you prefer you can use regular expressions to define your routing rules. Any valid regular expression is allowed, as are back-references.

Note: If you use back-references you must use the dollar syntax rather than the double backslash syntax.

A typical RegEx route might look something like this:
$route['products/([a-z]+)/(\d+)'] = "$1/id_$2";

In the above example, a URI similar to products/shirts/123 would instead call the shirts controller class and the id_123 function.

You can also mix and match wildcards with regular expressions.
