API/passive and skill gem info (I want to make a build/skill assist tool this summer)

hey, I want to get started on a build planning tool, however I'm looking for a place where I can import the passive tree from and get skill gem data.

there's a passive skill tree planner for windows (written in C# I think) but it's not open source (or I haven't been able to find the source) I have a hunch that's importing the passive tree from somewhere, but idk how it's done. I can figure something out for myself, but it seems like it's already been done, which would save me some time.

I could write a parser for the POE wiki to get the skill gem data (as I don't want to keep that up to date manually) but if this information is available in a decent format that would be great! (by that I mean having to parse some xml or json data instead of HTML wiki pages)

any suggestions?

thanks in advance!

http://www.pathofexile.com/passive-skill-tree

has a giant JSON variable with all the tree data in it. The URL encoding for a passive skill node selection is done in base64, "+", "/" replaced by "-" and "_".

I've got some haskell code I can send along if that will help. PM me.

awesome, thanks! I'll look into that, and yea, that would probably be helpfull (I've never touched haskell, but there's gotta be a first time for everything :P)
