in reply to extracting data

Always use strict; use warnings; it would tell you what's wrong.

There are two problems with your code. The first is that compare strings with ==, even though that operator does numeric comparison. And the second is that if there are only two chunks in the original string, $split_data[2] will not be the empty string, but undef.

So your test should look more like

if (!defined($split_data[2]) || $split_data[2] eq '0') { print $split_data[1], "\n"; }
