Is there a way for the code to ignore the whitespace or any type of null in the data file? 

while (<FILE>)
{
  if ($_ =~ /^$/)
  {
    print "it's blank\n";
    next; #process next line
  }
  else
  {
    print "it's NOT blank\n";  
  }
}

if($_ =~ /^$/) can also be written as if(/^$/)

All is well. I learn by answering your questions...
