I would use regex much more often once I have solved this fundamental question:
How to combine with logical AND in RegExp? For logical OR it's as easy like this: pattern_a|pattern_b This means literal searching for pattern "pattern_a" OR "pattern_b". (?=.*pattern_a)(?=.*pattern_b).* Is it easier to encode? On Wednesday, September 25, 2019 at 4:40:45 PM UTC+2, Mark S. wrote: > > regex is like a little, tiny condensed programming language.
