Hi!
This is a negative, zero-width, look-behind assertion (?<! \n ) It
means that the variable does not match what it contains, in this case a
newline, before the match but do not include what it matches in the match.
Huh? Until i read this, i actually though i understood regular expressions.
That one actually may solve one of my problems, too. Thanks!.. i think...
I'm going to have to meditate over that one.
LG
Rene
