I have two hashes (%a and %b) that contain data for one person from two
different systems and I want to compare these hashes to see if the
systems are out of sync. The catch is I know that some of the fields
will always be different and I want to ignore those fields. Below is my
solution, does anyone have a better way of doing this? BTW: there are a
lot of fields currently with more being added as time goes on and the
number of fields I want to ignore will stay pretty much the same).
<example>
my @ignore = ("key1", "key2");
KEYS: foreach my $key (keys %a) {
foreach my $ignore (@ignore) {
next KEYS if $key eq $ignore;
}
if ($a{$key} ne $b{$key}) {
print "$key is different ($a{$key}, $b{$key})\n";
}
}
</example>
