Hi,
It works fine and I like it. My regex is not that good, but I can see what
is doing. I modified it a bit (to capture up till a full stop sign).
<Code>
#!/usr/bin/perl
#
use strict;
use warnings;
#
my $str = "The black cat is trying to climbed the green tree. This time it
failed."; print "string: $str\n";
my $sbstr = substr $str, 0,17;
print "The substr function with length 17 will capture: $sbstr\n";
$str =~ m{ \A ( .{17} .*?\. ) \s }msx;
my $extracted = $1;
print "The pattern with quantifier set 17, extracted: $extracted\n"; <Code>
<Code>
Outputs:
string: The black cat is trying to climbed the green tree. This time it
failed.
The substr function with length 17 will capture: The black cat is
The pattern with quantifier set 17, extracted: The black cat is trying to
climbed the green tree.
Cool

Hi Shawn,

I don't think this would work if the value given in the match string (15 as
per above eg.) is greater than the character count of the particular string.
Right?
