A regular expression is a logical formula for manipulating strings, including ordinary characters (such as letters from a to z) and special characters (known as "metacharacters"). It is composed of predefined specific characters and combinations of these characters, forming a "pattern string" that expresses a filtering logic for strings. Regular expressions are text patterns that describe one or more strings to match when searching text.
