Ah sorry, I was typing so long and had an idle session that I didn't realize @r.david.murray added a comment with the explanation. Just to add I tried using Perl module (https://metacpan.org/release/Email-Address) that uses regex for parsing that returns me two addresses and the regex is also not much comprehensible. use v5.14; use Email::Address; my $line = 'John Doe [email protected] <[email protected]>'; my @addresses = Email::Address->parse($line); say $addresses[0]; say $addresses[1]; say "Angle address regex"; say $Email::Address::angle_addr; [email protected] [email protected] Angle address regex (?^:(?^:(?^:\s*\((?:\s*(?^:(?^:(?>[^()\\]+))|(?^:\\(?^:[^\x0A\x0D]))|))*\s*\)\s*)|\s+)*<(?^:(?^:(?^:(?^:(?^:\s*\((?:\s*(?^:(?^:(?>[^()\\]+))|(?^:\\(?^:[^\x0A\x0D]))|))*\s*\)\s*)|\s+)*(?^:[^\x00-\x1F\x7F()<>\[\]:;@\\,."\s]+(?:\.[^\x00-\x1F\x7F()<>\[\]:;@\\,."\s]+)*)(?^:(?^:\s*\((?:\s*(?^:(?^:(?>[^()\\]+))|(?^:\\(?^:[^\x0A\x0D]))|))*\s*\)\s*)|\s+)*)|(?^:(?^:(?^:\s*\((?:\s*(?^:(?^:(?>[^()\\]+))|(?^:\\(?^:[^\x0A\x0D]))|))*\s*\)\s*)|\s+)*"(?^:(?^:[^\\"])|(?^:\\(?^:[^\x0A\x0D])))*"(?^:(?^:\s*\((?:\s*(?^:(?^:(?>[^()\\]+))|(?^:\\(?^:[^\x0A\x0D]))|))*\s*\)\s*)|\s+)*))\@(?^:(?^:(?^:(?^:\s*\((?:\s*(?^:(?^:(?>[^()\\]+))|(?^:\\(?^:[^\x0A\x0D]))|))*\s*\)\s*)|\s+)*(?^:[^\x00-\x1F\x7F()<>\[\]:;@\\,."\s]+(?:\.[^\x00-\x1F\x7F()<>\[\]:;@\\,."\s]+)*)(?^:(?^:\s*\((?:\s*(?^:(?^:(?>[^()\\]+))|(?^:\\(?^:[^\x0A\x0D]))|))*\s*\)\s*)|\s+)*)|(?^:(?^:(?^:\s*\((?:\s*(?^:(?^:(?>[^()\\]+))|(?^:\\(?^:[^\x0A\x0D]))|))*\s*\)\s*)|\s+)*\[(?:\s*(?^:(?^:[^\[\]\\])|(?^:\\(?^:[^\x0A\x0D]))))*\s*\](?^:(?^:\s*\((?:\s*(?^:(?^:( ?>[^()\\]+))|(?^:\\(?^:[^\x0A\x0D]))|))*\s*\)\s*)|\s+)*)))>(?^:(?^:\s*\((?:\s*(?^:(?^:(?>[^()\\]+))|(?^:\\(?^:[^\x0A\x0D]))|))*\s*\)\s*)|\s+)*) Thanks ---------- _______________________________________ Python tracker <[email protected]> <https://bugs.python.org/issue34155> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
