client introduces caracters in ldap search

Hello,

 

 

'string map' doesn't seem to accept wildcards, so the best option I can think of would be to use regsub.

 

 

Here's an example:

 

 

% set mixed_string abcd1234abcd

 

abcd1234abcd

 

% set digits [regsub -all {[a-zA-Z]} $mixed_string ""]

 

1234

 

 

Here are a few related manual pages:

Else, you might be able to use scan:
