Hey guys - I have a script that loads a list of ~800,000 category hierarchies, filters them a bit and streams them through a PHP script for some quick procedural work. The file contains one column and a snippet looks like this:
Arts Arts/Animation Arts/Animation/Anime Arts/Animation/Anime/Characters Arts/Animation/Anime/Clubs_and_Organizations Arts/Animation/Anime/Collectibles Arts/Animation/Anime/Collectibles/Cels Arts/Animation/Anime/Collectibles/Models_and_Figures Arts/Animation/Anime/Collectibles/Models_and_Figures/Action_Figures Arts/Animation/Anime/Collectibles/Models_and_Figures/Action_Figures/Gundam Arts/Animation/Anime/Collectibles/Models_and_Figures/Action_Figures/Zoids Arts/Animation/Anime/Collectibles/Models_and_Figures/Models Arts/Animation/Anime/Collectibles/Models_and_Figures/Models/Gundam Arts/Animation/Anime/Collectibles/Shitajiki Arts/Animation/Anime/Creators Arts/Animation/Anime/Creators/Anno,_Hideaki Arts/Animation/Anime/Creators/Ikuhara,_Kunihiko Arts/Animation/Anime/Creators/Miyazaki,_Hayao Arts/Animation/Anime/Creators/Studios Arts/Animation/Anime/Creators/Studios/Studio_Ghibli Arts/Animation/Anime/Creators/Studios/Studio_Ghibli/Titles Arts/Animation/Anime/Distribution Arts/Animation/Anime/Distribution/Companies Now I need to take it one step further. I need to get a count of how many items are in "Arts", how many are in "Arts/Animation", etc. I know a grouping and count is involved, but I can't wrap my mind around how to get there since the category path depth is entirely variable and I need these numbers relative to the "whole" (i.e. I need to know how many times Arts/Animation/Anime appears rather than how many times Anime appears at any level). Any guidance would be much appreciated.
