in reply to Recognizing 3 and 4 digit number

I can't help but think there is more to this requirement than you've specifed, but based on what you've asked for, +a little bit more, try:

/\s\d{3,4}\s/ and print for 'abd 123 fred', '555-5555-6666', 'ab 12345
+ xd';;
abd 123 fred

    I put a backslash s in front of the backslash d and it works, but puts a percent 20 in the url. It still works but there must be another way. Thank you.

      If you don't want the space in the substitution, don't include it in the capture group! 

      $ perl -E'
my $re = qr/ \s ( \d{3,4} ) /x;
say ">$1<" if " 5678" =~ /$re/; 
'
>5678<

      The way forward always starts with a minimal test.

      Impossible :) nothing in that snippet does "value" encoding/escapeing
