Greetings all,
Given this code:
my $TOKEN_DELIMS = qr/[^\w\-'\$]/;
my $text = # string containing the contents of an mbox file
my @tokens = split /$TOKEN_DELIMS/o, $text;
I end up with a large number of null strings ('') in @tokens. After
RTFMing on split, I assume this is because I am matching at the
beginning/end of the string. I can't quite grok how to eliminate
these, however.
I can easily grep them out, but this is a time-sensitive routine, and
I'd rather just not generate them. How can I modify my pattern (or my
string, without losing real data), so that I don't get these spurious
matches?
Thanks in advance,
--Dks
