Test, validate and match regular expressions
This regex extracts visibility data from an HTML fragment with a specific structure, matching a div with class 'wfCurrentWrapper', a heading span, and a value span ending in 'km'. It uses backreferences to ensure consistent line breaks between elements, capturing the numeric visibility value. Useful for scraping weather data or parsing structured HTML snippets.
