Need help with string map replacing numbers

[kcrist84]

I need some help with a string map command. I am trying to replace special characters with a {}. For example if the number was 12456-21 i want 1245621, 1245a47 to 124547. I can get the special characters out, but how do i set it up to get rid of the letters. I have tried A-Z, a-z, A-z, chars with no luck. I am sure their is a way to do it so i dont have a {} b {} c {}...etc. All way through alphabet. So i basically want to take out anything non-numeric. Below is my current code, any help or direction would be appreciated.

set PolicyNum [string map -nocase {- {} ? {} . {} ' {} @ {} char {}}

Hi

Why not use [tt]regsub[/tt] ?

[b]set[/b] dirtyPolicyNum [green][i]"12456-21"[/i][/green]

[b]regsub[/b] [teal]-[/teal]all [teal]{[/teal][teal]\[/teal]D[teal]}[/teal] [navy]$dirtyPolicyNum[/navy] [teal]{}[/teal] cleanPolicyNum

[b]puts[/b] [navy]$cleanPolicyNum[/navy] [gray]# outputs 1245621[/gray]

string map will work with a map of, say {- ""}:

% string map {- ""} abc-123
abc123

Hi

Ok, but how can you remove simply the letters too ?

Sorry. I just realized what you were asking. I think you'd be better advised to go with regsub.

Thanks all for your replies and bear with me...but what does the {\D} mean? Does it mean everything but numbers?

Yes. See re_syntax for more.
