Questions tagged [regex]
Regular expressions provide a declarative language to match patterns within strings. They are commonly used for string validation, parsing, and transformation. Specify the language (PHP, Python, etc) or tool (grep, VS Code, Google Analytics, etc) that you are using. Do not post questions asking for an explanation of what a symbol means or what a particular regular expression will match.
