How to match a similiar word in the line and parse that word?	Can't Post

Hi guys,
Been a while since I been in here ... really need ya'lls help again.

I have an output assigned as an array variable. I have stripped the array of it's '\n' and I'm now trying to process the line.

What I'm trying to do, is try to match a particular string in the line, and parse the word in that line.

For eg:
I want to match a date..

$date = '090323';

to the line..

$data = "R081110000002JF R090323000450JF R081112000045JF R081210000077JF";

Now I would like my output to be..

R090323000450JF

after it's been matched and parsed.

So far I have this..

Code

if($data =~ /R$date/){ 
  $word = substr($data,0,0);    # This is where I'm stuck. 
  print $word; 
  }

Fish ... Kevin... can any of you guys help me here?

One possible way:

Code

$date = '090323'; 
$data = "R081110000002JF R090323000450JF R081112000045JF R081210000077JF"; 
my ($parsed) = $data =~ /(\bR$date[^ ]+)/; 
print $parsed;

Hi Kevin...
For some reason looking at your code struck a little match stick in my head. I came up with this script which you guys had previously written a while back.

Code

#!/usr/bin/perl 
 
use strict; 
use warnings; 
use Text::ParseWords; 
 
my $date = '090323'; 
my $data = "R081110000002JF R090323000450JF R081112000045JF R081210000077JF R090323004670JF"; 
 
my @words = &quotewords('[\s]+', 0, $data); 
my $i = 0; 
foreach my $word(@words){ 
  if($word =~ /R$date/){ 
    print "$word \n"; 
    } 
  $i++; 
  }

Thanks again guys.
