Regex exclude specific charater-CodePudding

I'm trying to extract the substring in-between two double quotes if present but I am only able to get the substring with the last double quote.

If the string has no double quotes, extract the substring

TEST STRINGS

"松嶋友里奈/ウェルキッズフォト" <[email protected]>
SuperBacker Team <[email protected]>
Medium Daily Digest <[email protected]>
"Tory @ Flippa" <[email protected]>
CocaCola <[email protected]>

My regex for python: "(?!\")(.*?)(?!\")(?=\s\<)"

ACTUAL RESULT

松嶋友里奈/ウェルキッズフォト**"** --> FAILED because of the double quote at the end
SuperBacker Team --> PASS
Medium Daily Digest --> PASS
Tory @ Flippa**"** --> FAILED because of the double quote at the end
CocaCola --> PASS

Why does my pattern include the double quote at the end but not at the beginning?

CodePudding user response：

((?<=^)(?=[^\"])|(?<=\")).*[^\"](?=\"?\s\<)

((?<=^)(?=[^\"])|(?<=\")) either beginning of string - not followed by " ((?<=^)(?=[^\"])) or starting after " ((?<=\"))
.*[^\"]anything that does not end in a double quote
(?=\"?\s\<) followed by optionally a double quote and then <
