Re: Making regex /g match continuously

As I understand your description, you want to match once, not multiple times. The expression either passes or fails, in entirety. You don't want /g. You want an anchor and a quantifier.

^
(?: ## added this
  (?:int)\s+(\w+)\s*?\n
  (?:\s*Number\sof\sFlaps:\s(\d+)\s*?\n)?
  (?:\s*IP\sAddress:?\s([\d\.]+)\s*?\n)?
)+\Z ## changed your last line

This will match one or more repetitions of your int/Flaps/Address pattern followed by the end of the string.

That would work, but the problem is that the $1, $2, $3 variables will only be set to (IIRC) the last values. So if you want to just test if the value matches, that's fine, but if you want to do something with the values, it's not as useful.	[reply]
