Text/stats data extraction from client possible ? : LOTROExtreme

Yes i know - all english available in lotrobooks.
This way not good for me, because i looking info about localized data (german/russian etc).

Can someone give (or sell) me any information about this problem.
Ideal solution for me: any utils for extract dta directly from client file (if data dstored to client). Not ideal - any solutio for dump data if i see it data in client.

Any ideas ?
