yariv , There is no official method. You might explore  the <LG-Install-Path>\Temp\brr_* directory. The most recent one. 

Your script has as current directory the script-dir itself. This is down the path that I mentioned. So you could traverse up the path to find the files you are looking for. But this is 'internal' structure and might change from version to version. You need to explore (reverse engineer) the details yourself.

Note that some logging is in pure binary format as well. All data is collected at the Controller and put together in a RawResult directory.

Could you explain what you want to achieve, there might be more solutions to your problem
