read and parse XML of kodi nfo files with bash

Question

I have a folder with movies initially created with kodi, so they all contain a kodi .nfo file. (example nfo file)

I want to loop through the folder with a bash script and rename the foldernames accordingly to the data in the contianing nfo files so they follow the rule

"title - country of production YY - genre - resolution - short description - the three main actor's names.fileformat"
