Regex to match the pattern

Question

I need to match the regex that matches the sentence with following pattern:
1st part is occurrence of word/s.(eg: passed, died)
2nd part is the date in that sentence.
3rd part is, this should match only before the delimiter/dot/full stop.

Example: Worth Scattergood (Dee) Lea passed on Thursday, July 28, 2022 , Worth Scattergood (Dee) Lea passed away unexpectedly at age 88 with her three daughters at her side. Dee was born on April 26, 1934, in Radnor, Pennsylvania.

Here i need result of: July 28, 2022

But this should not match or find any result in following sentence:
Worth Scattergood (Dee) Lea passed on Thursday. Dee was born on April 26, 1934, in Radnor, Pennsylvania.

I tried with following expression but it is wrong as it match upto second sentence:

(passed|died)(.*?)(\w+)\d{1,2},?\s?\d{4}

Answer 1

You can match keywords passed or died and then allow upto 3 space separated substrings before matching date:

\b(?>passed|died)(?>\h+\S+){0,3}\h+\K\w+\h+\d{1,2},\h*\d{4}\b

RegEx Demo

Explanation:

• ?>...) : is atomic group
• \b : Word boundary
• (?>passed|died) : Match passed or died
• (?>\h+\S+){0,3} : Match 0 to 3 space separated substrings
• \h+ : Match 1+ whitespaces
• \K : Resets matched info
• \w+ : Match month name
• \h+ : Match 1+ whitespaces
• \d{1,2} : Match date part 1 or 2 digits
• ,\h* : Match comma followed by 0 or more whitespaces
• \d{4}\b : Match 4 digit year followed by word boundary

Answer 2

You can use

\b(?:passed|died)\b[^.?!]*?\b(\w+\s*\d{1,2},\s?\d{4})(?!\d)

See the regex demo .

Details

• \b(?:passed|died)\b - a word boundary, a non-capturing group matching either passed or died (as whole words) and a word boundary
• [^.??]*? - zero or more chars other than . , ! and ? as few as possible
• \b - a word boundary
• (\w+\s*\d{1,2},\s?\d{4}) - Group 1: one or more word chars, zero or more whitespaces, one or two digits, comma, an optional whitespace, and four digits
• (?!\d) - no digit immediately on the right is allowed.
