In that case, your “null” corresponds to the empty string, so you can test for true or false (because the empty string is “false” in Perl):

next if !$ex_date;

But it’s better (because clearer) to make the test explicit:

next if length $ex_date == 0;
# or
next if $ex_date eq "";

Hope that helps,
