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

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.
