Regex Editor & Tester

This regex matches lines containing text between ampersand (`&`) delimiters and captures the content between them into group 1. The non-greedy quantifier `+?` ensures it captures only the content between the first pair of ampersands. With the `gm` flags, it operates across multiple lines and finds all matches. It's useful for extracting tokenized values from delimited strings such as URL query parameters or custom data formats.
