Re: ignoring empty returns from split

You could knock yourself out, such as: my ($one, $two) = grep { $_ } split (/exp/, $line); Or, you could just use the split parameters: my ($one, $two) = split (/exp/, $line, 2); Where 2 is the limit on the number of parameters you want back.

Or, you could just use the split parameters: `my ($one, $two) = split (/exp/, $line, 2);` This will break for cases of "=0==one=two" since you'll return an empty and a zero. For those suggesting a simple $_ test for the grep, you will not return the 0. Best to go with the length() function. Update: I'd have to go with Ovid that `"length > 0"` is clearer than just length, but might there be a performance hit? (And would this code really be hurt by the performance hit?)
