Thanks you for your response. I tried your code and it is awesome! However , I cannot get the output after i tried to modify your code. i want to get the input by using the $ARGV method.

#!/usr/bin/perl


use strict;
use warnings;
use Data::Dump 'dd';
my $input1=$ARGV[0];
my $input2=$ARGV[1];
open my $fh1, '<', $input1 or die "Cannot open file : $!\n";
my %hash1 = gethash($fh1);
close $fh1;
open my $fh2,'<',$input2 or die "Cannot open file : $!\n";
my %hash2 = gethash($fh2);
close $fh2;

dd 'file1', \%hash1, 'file2', \%hash2;

print "\t\tFile1\t\t\t\t\tFile2\n";
print "Name\tX1\tY1\tX2\tY2\t\tX1\tY1\tX2\tY2\n";

for my $key ( keys %hash1 )
  {
  my $name = $key;
  for ( match( $hash1{$key}, $hash2{$key} ) )
{
    print "$name\t$_\t\t$_\n";
    $name = '';
    }
  }

sub match
  {
  my ($one, $two) = @_;
  my @same;
  for my $item (@$one)
    {
    push @same, grep $item eq $_, @$two;
    }
  return @same;
  }

sub gethash
  {
  local $_ = shift;
  s/^\s+//gm;
  s/[\t]+/\t/g;
  my %hash;
  while(/^name\s+(\S+)\n(num.*\n)*/gm )
    {
    my $name = $1;
    $hash{$name} = [$& =~ /^num\s*(.*)/gm ];
    }
  return %hash;
  }
