Split string at n'th space in n'th length

kylomas,

I think I was right about the "\K" - if we protect the characters by capturing them and then adding them to the replacement it also works:

StringRegExpReplace($sString, "(.{1," & $x - 1 & "})(\s{1,2}|$)", "$1" & @CRLF)

So when the Help file speaks of "similar but not identical to a look-behind" it means that "\K" protects the previous group just as does a "look-behind/ahead" structure.

one more way...

Local $sString = 'A child asked his father, "How were people born?" So his father said, "Adam and Eve made babies, then their babies became adults and made babies, and so on." The child then went to his mother, asked her the same question and she told him, "We were monkeys then we evolved to become like we are now." The child ran back to his father and said, "You lied to me!" His father replied, "No, your mom was talking about her side of the family."'

$x = 74
For $i = $x to StringLen($sString) Step $x
    $i = StringInStr($sString, " ", 0, -1, $i)
    $sString = StringReplace($sString, $i, @CR)
Next

MsgBox(0, '', $sString)

Caduceus (Maynard James Keenan of Tool's winery) has a Merkin Chupacabra Blanca that is part gewurztraminer, part Riesling.  Best I've had since i left Europe.

Melba,
Your guess is right 
\K is a pretty nice thing. In a SRER all chars mentioned in the pattern before \K are 'protected' indeed

A little example : let's say you want to replace the 3rd occurence of 'cat' by 'dog'
The first run until 'cat' is found, then the second one, and the third one before the 3rd 'cat' are 'protected'

$str = "the first is a cat, the second is a cat, the third is a cat, the fourth is a cat"

$res = StringRegExpReplace ($str, '^(?:.*?\Kcat){3}' , 'dog' ) 
Msgbox(0,"", $res)

Gewurtz is pretty good, though my preference goes to the Riesling which is drier (personal taste)
