Hi monks,

Can anyone tell me if it is possible to combine the following two regex's into one? 
#/usr/bin/perl

use strict;
use warnings;

my $string =<< "END";
("Immunologic and Biological Factors"[MESH] OR "Immunosuppressive Agen
+ts"[MESH] OR "Transplantation Immunology"[MESH] OR "Allergy and Immun
+ology"[MESH] OR "Graft vs Host Disease"[MESH]) NOT ("Foo"[MESH] OR "B
+ar"[MESH]) AND ("Kidney Transplantation"[MESH] OR "Liver Transplantat
+ion"[MESH] OR "Heart Transplantation"[MESH]) NOT ("My Term"[MESH] OR 
+"Blah"[MESH]) NOT "foobar"[MESH]
END

# This removes all instances of 'NOT "anything"[MESH]'
$string =~ s/ NOT ".*?"\[MESH\] ?//g;
# This removes all instances of 'NOT (anything)'
$string =~ s/ NOT \(.*?\) ?//g;
