[Regexp] complicated regexp question

[Igor Vaysenberg]

Hi,
I need to write regexp that could recognize all the follow strings 
starting from '%':

 no crypto ca identity RSVP-Test.cisco.com
% Removing an identity will destroy all certificates received from
 the related Certificate Authority.

Are you sure you want to do this? [yes/no]:
% Please answer 'yes' or 'no'.
Are you sure you want to do this? [yes/no]:  y
% Be sure to ask the CA administrator to revoke your certificates.

No enrollment sessions are currently active.

ios-mdc-7400-196(config)

% Invalid input detected at '^' marker.

ios-mdc-7400-196(config)#

% Error bla-bla in module

thanks
