I have got a path (string) like the following: /food/fruits/apple
I have got also a nested set which is managed by doctrine (and it is
managing it very good and I am very happy with that).

Now I want to resolve this nested set with the path I have described
above.
- Is that possible with native doctrine facilities?

There is also another thing you have to take care of: Sometimes you
can resolve the path to a specific point.
- Then you get something like artifacts, because the path segments
don't reflect the nested set entries anymore.
Those artifacts I also want to retrieve in an array because I need
them later.

Btw.: There is also a materialized path-implementation for doctrine.
However - the class is still empty.
And I like the nested set modell - so I am looking for a solution for
traversing it with a given path (string).
