I wrote a prototype AIML parser that works in WoD if you want to use it. It isn't 100% functional as there are some glitches and unsupported features. I only wrote it to revive an old addon by request. It's embedded into a working copy of the AIBot addon that I rewrote from the ground up. All of the AIML brain data and the init vars were left unchanged.

PS: I don't think the new AIML storage format mentioned later on the thread made it into the addon by the time I stopped development on it. The size of the brain table after converting the source AIML files would've required another rewrite to squeeze out as much performance as I could.
