Test, validate and match regular expressions
Matches sequences of whitespace characters (spaces, tabs, newlines) and self-closing tags in markup languages. The pattern alternates between matching XML/HTML self-closing tags like <br/>, individual whitespace characters, and newlines. Useful for tokenizing or sanitizing markup by identifying elements that should be handled as separators or standalone elements.
