How to match number greater than 50 before specific char with regex?

@lew 

You can use the following regular expression to match a number greater than 50 before a specific character:

1

[5-9][0-9]+(?=specific_char)

Explanation of the regex:

• [5-9]: Matches a digit between 5 and 9.
• [0-9]+: Matches one or more digits after the first digit.
• (?=specific_char): Lookahead assertion to ensure that the matched number is followed by the specific character.

Make sure to replace specific_char with the actual character you want to match after the number.
