Always supply a complete snippet. This should be what you need, but
not sure exactly:
use strict;
use warnings;
my $hardware1 = '';
my $hardware2 = 'hardware2';
my $hardware3 = 'hardware3';
my $hardwareValue1 = '';
my $hardwareValue2 = 'hardwareValue2';
my $hardwareValue3 = 'hardwareValue3';
my $some_data = [
['HP Hardware', 'Total Cost'],
[$hardware1, $hardwareValue1],
[$hardware2, $hardwareValue2],
[$hardware3, $hardwareValue3],
];
for (my $ii = 0; $ii < @$some_data; ) {
if ($some_data->[$ii][0] eq '') {
print "$ii empty - deleting\n";
splice @$some_data, $ii, 1; # drop row
next; # skip inc of $ii since array shortened
} else {
print "$ii $some_data->[$ii][0]\n";
}
++$ii;
}
__END__
