Inverting regsub's functions

Fill · Post by **Fill** » Wed May 06, 2009 10:55 am

Hey guys,

I'm using regsub to check if a variable matches a regular expression and if it does, regsub will replace the part that matches by what I want and assign that to a new variable

however, I wanted to make the opposite. I want regsub to assign the part of the variable that matched the regular expression to a variable. How can I do this?

Use Regexp

Code: Select all

set txt SomeTextHere
regexp -all {Text} $txt new

$new will contain the match, in this case "Text"
