Keypaths

Hi, I've implemented a little tree through my class Node that contains the properties NSString* name and NSMutableArray *subnodes

I'd love to say something like "Give me the nodes that have a grand- father named Balbo Baggins and father named Ponto Baggins" (should be Rosa and Polo Baggins) How do I express this with keypaths? How should I make a keypath that returns an array of Nodes and another keypath that creates an array of NSStrings with only the name properties of the nodes?

Cheers

	Nik
