Hello all!

Actually I'm not sure how to defined my question based on specific title, I will try to explain more here then.

Text 1:

Entry 1
1 N
2 D
EOE

Text 2:

Entry 3
6 N
7 
EOE
Entry 5
4 D
9 D
EOE

Text 1 has 1 entry while text 2 has 2 entries. What I wish to do is to compare the contents of entry by entry between files and so on. For example above,both files have first entry then it will proceed to comparison. But, Text 1 does not contain second entry as Text 2 then output a warning message" Text 1 has missing content".

use strict;
use warnings;
my (@data1,@data2);
my (@array,@array2);

open my $fh, '<', 'Text1' or die "Could not open file to read:$!";
while (<$fh>) {
        if (/^\Entry (\w+)/../\EOE/){
        push @array, $_;
        if (/^(\Entry)/){    
            push @data1 ,$1;
                    }
    }
}

open $fh, '<', 'Text2' or die "Could not open file to read:$!";
while (<$fh>) {

    if (/^\Entry (\w+)/../\EOE/){
        push @array2, $_;
               if (/^(\Entry)/){
        push @data2 , $1;
                    }
    }
}
print @array2;
my $size = @data1 < @data2 ? @data1 : @data2; 
my $result= @data1 < @data2 ? "File 1 has missing data" : "File 2 has 
+missing data";
my $ori = @data1 == @data2 ? 1:0;
my $i;
for( $i = 0; $i < $size; $i++){
       if ($data1[$i] ne $data2[$i]){
        printf "%s is mismatch with %s\n",$data1[$i],$data2[$i];
       }
       else {
       &compare();
}
}
print "$result\n" if (!$ori);

I do not include the subroutine here. I would like to ask if any idea to store content of each entry specifically to ease the comparison work? I have tried array but it stores content of all entries as it has. Instead access to the content of entry 3, it access to all content of text 2. Is hash able to do so? Any suggestion is much appreciated. I am not expecting any codes but some suggestion on which functions or method would really be a big help. I am trying to write Perl myself. Cheers.
