[WebDNA] How to NOT remove the dot via grep ...

It keeps the original formatting. numero = 103322
interpreted = N
texte = Bob Minor posted some code the other day that illustrates the use of grep to strip out all characters except for numeric digits:> [grep search=[^0-9]&replace=][value][/grep]My goal is to do nearly the same thing, but I want to leave the dot (.) character in the resulting value so it will be a floating point value. At first I was going to use this code:[listchars chars=[value]][showif 1234567890.^[char]][char][/showif][/listchars]... but I think grep might be more efficient if it were written properly. I only wish I knew how.Does anyone know grep well enough to suggest a grep search string that would leave not only the numeric digits but also a decimal point in the resulting value? Sincerely,Ken Grome Associated Messages, from the most recent to the oldest:
