[Website] Extract Mapdata - How does it work?

[DragoonZombie]

Ok, I've wanted to know this for a long time already.
I've searched alot on various wc3 modding websites, but couldn't find anything.

The thing I want to ask is, how does the hive's, epicwar's and wc3sear's map upload script access the data from the maps?

I would have tried to do it by myself, but the thing is, that I have absolutely no clue how to even open the map file so the data is readable.

I don't need it for anything atm., I just like to know how it works.

If you don't like to show the script to the public for I-don't-know-what-reason, could you at least give me hints on how to start?

Thnx in advance.

open it as any other binary file, and extract the info?

you can find .w3x specification somewhere (I think PitzerMike has one on wc3c)

The method they use is to extract the nessisary files from the MPQ (map files are basically just MPQ archives) and read all the wanted data from them at the time of upload. Its just your basic file-reading system, really. (with the added complication of MPQ archival)
