Re: stripping everything but numbers and letters

Tested it.
It works, but what I meant to ask, is if there is a down fall to doing it that way, or if there is a better way to do it?

I might use this, `$string =~ s/[^\w\d.-]+//g`, but it's nearly the same thing. I think it's just fine. -Paul	[reply] [d/l]

I don't understand: When you said 'number' in your OP, did you mean 'decimal digit', i.e., '0' through '9' (as represented by the character set `[0-9]` or `\d`), or did you mean something like 'signed integer' or 'rational number', e.g., '-21' or '+4.2'? I notice that you and some other posters include '+', '.' and '-' in their character sets, which suggests a 'rational number' interpretation. If this is the case, you definitely need a different approach.	[reply] [d/l] [select]
