I allways suffered a lot running RoboLeague, something like 5 seasons of 35 rounds match in a TestBed of 20 bots or how. And also suffered after, trying to excel the results of those many tables.
In order to to help me analyse the results of RoboLeague, i built this modest analyser.
It reads the .xml file resulting of running RoboLeague division mode, focused in your bot, against a TestBed of n bots in m seasons. Process The info of the xml and give me an output as a table with this kind of colums: 

dos.writeBytes("Opponent" + sep + "PBI(%)" + sep + "My score" + sep
					+ "Opp Score" + sep + "My bull.dmg." + sep
					+ "Opp bull.dmg." + "\r\n");

Averaged by the seasons quantity.
That means that i have now a single table with the results averaged. This by itself is usefull to me, but the real reason that made me post this, is that it is a very simple code accessing the output .xml file of RoboLeague, and demontrates the basic manipulation of xml structures with Java APIs. Its very crude and simple, but I prefer that way, it is (i think) easier to understand and adapt/use. Feel u all free to use this code (RWPCL).

Usage: axe.LeagueAnalyser <RoboLeague_xml_file> <bot_name_with_underscore_in_spaces>
