Hi Gerd,
It was foretold that on Tuesday, December 11, 2001 at 11:14 GMT +0100,
Gerd Ewald [GE] would type:
>> You're missing ranges. One that might work better is:
>> (\d|\d\d|[01]\d\d|2[0-5][0-5])\D
Heh, mine is wrong too. Mine will miss 206-209, 216-219, 226-229,
etc.
GE> When I wrote mine I remembered a regex which was printed in *Friedel*,
GE> but was too lazy to look it up. Here it is:
GE>
([01]?\d\d?|2[0-4]\d|25[0-5])\.([01]?\d\d?|2[0-4]\d|25[0-5])\.([01]?\d\d?|2[0-4]\d|25[0-5])\.([01]?\d\d?|2[0-4]\d|25[0-5])
That'll work.
GE> Still 0.0.0.0 is possible, but this another story.
Friedel's regexp will catch this case too. We can take this to TBTECH
if you want to know how.
Hints: 1. Look at the first alternative for each set of numbers.
2. Remember, \d matches *any* digit.
3. What does the repeat operator '?' do?

OK, I'm weird! But I'm saving up to become eccentric.
