text output with each RegionPersonDisplayName on one line

[Iwonder]

@StarGeek
You saved me ! 
it's working fine ! I would'nt have guessed it alone, there so much thing to read and understand about exiftool ! and I only read about getting output !
Yes, I get dashes, for lines without RegionPersonDisplayName and/or RegionRectangle but I can easily get rid of that with a simple sed.exe command.
I thank you very much for taking time to look and test !
