I've only used Perl for scripting, so I'll give you some advice for Perl.

Read rules.txt and read each line.
If the line has any of those keywords in defaultRules, then do nothing.
Else, put that line into an output file rules.out

Code:
open(INPUTFILE, "<rules.txt");
open(OUTPUTFILE, ">rules.out");

while (<INPUTFILE>) {
    my $line = $_;
    if ($line =~ m/IPSEC_AH/i || $line =~ m/IKE_UDP/i || $line =~ m/IPMP_TEST_IFACE2/i) {
             print OUTPUTFILE "$line";
    }
}

close(INPUTFILE);
close(OUTPUTFILE);
