Build, test, and debug regular expressions
Matches content between a pair of simple HTML/XML tags: an optional possessive opening tag (e.g., <div>), lazily captured inner text, and a required closing tag (e.g., </div>). Commonly used to strip markup from text or extract the content inside tags. The possessive quantifier (?+) prevents backtracking on the opening tag, and only lowercase alphabetic tag names are supported.
