Hi, guys, I am new to Perl and I have to use RecDescent module to parse a complex design log file. I got some problems of the parser's usage. Here is a simple example.
say I got a file like below: 
======= START OF FILE ==========
No  Name Score Prize
1   Pig  100   red flower 
2   Han  80    bread
3   Hen  50     ass kicked
======= END OF FILE ==========

I need to parse the data of every row and print them one by one. My perl is: 
############### START OF PERL ###################
#! /usr/local/bin/perl -sw

BEGIN {
        close STDERR and open STDERR, '>./STDERR' or die $!;
}
use Parse::RecDescent;

#============================================
# GRAMMAR DEFINITION HERE
#============================================
$grammar =
q{
    Para:       List(s) /\Z/
                | { use Data::Dumper 'Dumper';
                    print "$_->[0]\n" for @{$thisparser->{errors}};
                    exit;
                    }
    List:       Order Name Score Prize
    
    Order:       /\d+/ {print "@item\n";}
                | <error: 1>
                
    Name:       /\w+/ {print "@item\n";}
                | <error: Expecting a name!>
                
    Score:       /\d+/ {print "@item\n";}
                | <error: 2>
                
    Prize:      /.*$/ {print "@item\n";}
                      
};

#============================================
# MAIN PROGRAM STARTS HERE
#============================================

$parse = new Parse::RecDescent ($grammar);

while (<DATA>)
{
    chomp;
    
    $parse->Para($_);
}

__DATA__
1   Pig  100 red flower 
2   Han  80  bread
3   Hen  50  ass kicked
############### END OF PERL ###################

You know it works fine. But when the input data format changed to the following: 
======= START OF FILE ==========
No  Name Score Prize
1   Pig  
  100   red flower 
2   Han  80
    bread
3   
  Hen  
     50
      ass kicked
======= END OF FILE ==========

The perl won't work for it. I added <skip: qr/[\s\t\n]*/> to the List but it is fail to parse. How can I make it to deal some irregular text formats?
