Here's an example string: 
confederation-as-router: 1 3277 myrouter1-cr2

[download]
I can match everything that I DO want, just not what I DONT want. I've got: 
$_ =~ s/^confederation-as-router\:\W+\d\W+\d+\W//

[download]
This would return: 
dsdfge1-cr4

in the above example. I want the regex to match any entries NOT ending in cr(digit).
