I'm trying to select a word that is on the second line, but first I need to check if there is a word on the first line, regex 
Why doesn't this regex work when isaac precedes select?
How can I solve this?
CodePudding user response：
You can change issac so it is in a non-capture group, and allow for anything until select is present.
(?s)(?:isaac.*)(select)
The (?s) modifies the . operator so it allows for new lines as well.

Since the two words are given there is no point to select the word in the second line; it is enough to determine if the first word is in the first line and the second word is in the second line.
The needed regular expression is simple:
.*isaac.*\n.*select
