Hello, @adam-bowsky, @michael-vincent, @supasillyass and All,
Personally, I would use the following regex S/R, which should work in all the discussed cases !
I simply assume that the N90- string, with this exact case, is preceded with, at least, one digit !
SEARCH (?-si)^\h*\d+N90-.*\R?
REPLACE Leave EMPTY
Of course, the Regular expression search mode is selected and the Wrap around option is ticked
Give a try !
I’ll give you some explanations when everything is right ;-))
Best Regards
