In which way > this does fail? Don't make us solve riddles ;-) (replace-regexp-in-string (rx (one-or-more (any whitespace))) " " "Hello there and here") ⇒ "Hello there and here" new line is not removed with character class `whitespace'. (replace-regexp-in-string (rx (one-or-more (or "\n" (any whitespace)))) " " "Hello there and here") ⇒ "Hello there and here" So now it will work that way. -- Jean Take action in Free Software Foundation campaigns: https://www.fsf.org/campaigns In support of Richard M.
