How about just a vector of vector of integers? Each integer would represent the nth child of the previous node, and each vector of integers would represent a whole nodepath. So "4 6 7" would mean the 7th child of the 6th child of the 4th child of the root node. -- Terry Welsh mogumbo 'at' gmail.com www.reallyslick.com
