Subject: Xpath like syntax

Hi all,

curious if there is a nice ruby way to express an xpath like navigation of an 
object graph..

ie: 

XPATH way:
Countries/Provinces/Cities[ @name = "London" ]

versus

The only Ruby way I can think of:
countries.collect{ |c| c.provinces.collect {|p| p.cities.select { |c2| c2#name 
== 'London' } } }

Thanks in advance
