Test, validate and match regular expressions
Matches a single space adjacent to HTML tags: either a space immediately after a tag's closing '>' when the next character starts a word (positive lookbehind plus word boundary), or a space immediately before a tag's opening '<' when preceded by a word character. Typically used with global matching to find, trim, or strip stray whitespace wrapping inline HTML tags during text cleanup and sanitization.
