Re: Regex matching next occurrence or to the end of line.

I may have misunderstood what you are asking for, but I think the solution to your problem is look-ahead assertions.

m< 
  (?:            # A char that is:
   [^\$]         #   Not a $
   |             #   Or
   \$ (?! {= )   #   A $ not followed by {=
  )+             # Many times
>x;

Many thanks for your response Eily. I have not used look-ahead assertions before. Useful stuff and it looks like what I need... I have had a reply from a colleague at work with a slight modification to the regex I was using. This works - `if ( $string_exp =~ m/\Q$placeholder\E(.*?)((\$\{)\|\z)/ ) { print "\"$1\"\n"; }` [download] This matches up to the next occurrence of the literal `${`, otherwise to the end of the string. Thanks again.	[reply] [d/l] [select]

This matches up to the next occurrence of the literal ${, otherwise to the end of the string.

Thanks again.
