What about using a boost::transform_iterator<>? Docs at:

  http://boost.org/libs/iterator/doc/transform_iterator.html

You'd have to supply it with a function object that returns the 'second'
member variable of the pair, e.g.

 struct get_pair_value
 {
     template< typename K, typename V >
     V operator()( std::pair< K, V > const& pr )
     { return pr.second; }
 };

Or you could use Boost.Lambda.
