Test, validate and match regular expressions
This PCRE regex matches any HTML tag except for opening or closing `strong`, `h1`, `input`, and `b` tags. It uses a negative lookahead to bypass those specific elements, matching all other tags non-greedily. It is useful for sanitizing or parsing HTML when you need to strip most tags while preserving specific formatting or structural elements.
