Regex :: How To Parse String (Similar To Path)

I have a string that is similar to a path, but I have tried some regex patterns that are supposed to parse paths and they don't quite work.

Here's the string
f|MyApparel/Templates/Events/
I need the "name parts" between the slashes.
I tried (w+) but the array came back [0] = "f" and [1] = "f".
I tested the pattern on [URL] and it seems to work correctly.

Here's the AS code:
var pattern : RegExp = /(w+)/g;
var hierarchy : Array = pattern.exec(params.category_id);
params.name = hierarchy.pop() as String;
