Regex Match first occurrence

I have a huge text file containing various articles and I am trying to extract lines from it using regex. I know that the line below the title starts either with For/From (most of the times) I wrote the following regex but if there are articles that have paragraphs starting with From/For, it matches the title until the paragraph. How do I make the regex match the very first occurrence of For/From? 

((?<=\n)[A-Z].*\n+(?=(?:(?:From)|(?:For))))

It seems likely that you are using the /g flag. It is possible that removing that may fix your problem, as you don't want to match all occurrences, only the first one.

Make your quantifier non-greedy.

((?<=\n)[A-Z].*?\n+(?=(?:(?:From)|(?:For))))
               ^
