Deriving controller/action from a RESTful URL

If I have a URL/PATH generated via Rails routing:

edit_foo_path(foo)) => “/foo/1;edit”

…is there some way that I can take that string and get its component
parts (controller, action, id, etc)??

I’m specifically looking for a solution that doesn’t involve me coming
up with a regex. I want to rely on code with Rails (which clearly
must exist).
