Regex Editor & Tester

This regex matches a hidden HTML input field specifically named "_csrf" and captures its value, which typically contains a Cross-Site Request Forgery (CSRF) token. It enforces a strict order of attributes (type, value, name) and uses a non-greedy capture group to extract the token string. It is commonly used in web scraping, automated testing, or HTTP clients to fetch necessary CSRF tokens for subsequent authenticated POST requests.
