Test, validate and match regular expressions
Matches HTML anchor elements linking to facebook.com, starting at the opening `<`, lazily consuming non-`<` characters until a lookahead confirms 'facebook.com', then continuing over any characters (including newlines, via the JavaScript `[^]` any-char trick) until the closing `</a>`. Used with the global flag to strip Facebook hyperlinks and their wrapped content from HTML strings, common when sanitizing scraped markup or removing social media links.
