Fella Monks...

The code below is a demo of my attempt at
writing a little function to retreave N first
sentences from a string.  I wonder if there
would be any suggestion on your part as to 
other implementations to achieve similar results?

Cheers,
c0d34w4y


my $s = "foo. bar. foobar. foo bar.";
my $p = get_nsentences($s,2);  # $p = "foo. bar.";

print $p;
print "done\n";

## SUBS

# get n first sentences from a given string.
sub get_nsentences {
    my $source_txt = $_[0];
    my $ret_txt = "";

    # i know this looks twisted...
    for($i=$_[1]||1;$i>0 && length($source_txt);$i--) { $source_txt =~
+ s/([^\.]+\.)/(($ret_txt.=$1)&&"")/e; }
    return $ret_txt;
}
