Take a look at path::branch(). It essentially does the "traverse up" one

There is a such an iterator; it is called path::iterator. Path has begin()
and end() functions returning path::iterators. Dereferencing a path
iterator returns a string containing that element of the path sequence.

The path::branch() and path::leaf() functions should take care of many
common needs, while the iterator w/begin() and end() can be used to handle
the less common needs.
