Test, validate and match regular expressions
Matches lines containing two captured pieces of data: first, word/space text appearing after a colon plus whitespace and followed by a 5-digit ZIP code in parentheses (e.g., 'City: Springfield (62704)'), and second, an email address preceded by whitespace. With global and multiline flags, it is useful for parsing logs, contact records, or address lists line by line, extracting locations and emails into capture groups.
