# Say you want all lines between the line "first-line-excluded" and "last-line-excluded"
Regex = "first-line-included((?:\s|.)*)last-line-included"
# Set the "Multi-line" option to true

# E.g. If the text has this form
	# before first line
	# first-line-included
	# 1
	# 2
	# ...
	# last-line-included
	# after last line
# the regex will return 
	# first-line-included
	# 1
