Hey Yurai,
really nice work *thumbs up*
I wrote a (very small) LogParser by myself in Java. There's also a logparser webproject in python somewehere out there.
I took a short look on the code, really nice coding style. But some of the for-loops are kinda crazy, haha Maybe i can help you port your programm for german logs. But I'm a bit short on time right now...
