Question

I have a text file with this format:

('1', '2', '3', '4', '5');
('a', 'b', 'c', 'd', 'e');

etc…

I want from each line the third and the fourth entry in the ''

My Text file has 125k lines so it is something big.

Thank you

Answer 1

^.*?,.*?,(.*?),(.*?),.*

will get you the third and fourth fields in \1 and \2 (assuming no commas will appear between quotes, that you wish not to be treated as delimiters, or anything like that).

When run on your example, replacing with \1,\2, the end result is:

 '3', '4'
 'c', 'd'
