A regular expression that matches blank lines (lines that contain only whitespace or are completely empty) is:
^\s*$
Explanation:
^β Matches the beginning of the line.\s*β Matches zero or more whitespace characters (spaces, tabs, etc.).$β Matches the end of the line.
This regex ensures that lines that contain only whitespace (or nothing at all) are matched.
