I have a list of tags such as Fiction.Cultures & Regions.Canada and Nonfiction.Cultures & Regions.Asia.China.

I'd like to remove any tag including "Cultures & Regions" from the list before splitting it.

I tried a regex list_difference but it didn't seem to work:

Code:

program:
	list_difference($tags, '(.*)Cultures & Regions(.*)', ',');)

(Additionally, I also want to do the same with something like a list_intersection to extract the culture & region items.)
