How about:
[array filterUsingPredicate:[NSPredicate
predicateWithFormat:@"SELF.length > 0"]];
"LIKE" is awfully fancy for the purpose.

Thanks guys, except now I'm having a new problem. My array of lines is
now containing empty strings that actually report a length of zero.
This would be fine, except when I try to filter the array to get rid
of these empty lines,
[array filterUsingPredicate:[NSCompoundPredicate
notPredicateWithSubpredicate:[NSPredicate predicateWithFormat:@"SELF
LIKE %@", @""]]];
this code has no affect. These empty strings have a length of 0 so
they would have to be just empty strings. Other filtering predicates
work fine. Is this a problem with the predicate?
