Yes, but it's quite hairy.  If interested in details, check out look-around 
assertions in the Perl regular expressions documentation ("man perlre" in 
Unixish systems).

This should work for http://a.example.com:

-X '(?!^http://a\.example\.com).{20}/'

The magic number 20 is the number of characters in http://a.example.com.  For 
https://foo.example.com it would be 23 etc.
