i try to read two different files into a array and compare
both and print difference between fil0 > file1 (both files
have a identical construction, see __DATA__

Problem:
--------
-Need to compare EntityName & m_LocalNbrPhysAddr for every
element (each data element starts with { and ends with },
at the moment i compare each key seperately,and print out the difference.

Finale solution i need:
-----------------------
-read in EntityName,m_LocalNbrPhysAddr,m_ConnectedTo between the { } data context into
a hash from file0 and do the same with the file1 and
compare both
THANKS FOR ANY SUPPORT !

my lame code:
-------------

for my $data (<FILE34>) {
    foreach my $line (split /};/, $data) {
        next if $line eq '';
        next if $line =~ m/^\s+$/;
        next if $line =~ /^\{$/;
        next if $line =~ /^\}$/;
        #$line =~ s/\s+//g;
        $line =~ s/\;//g;
        my ($key, $value) = split(/'/, $line);
        
        if ( $key =~ /EntityName/ ) {
            next if $value eq '';
            $value =~ s/\.domain\.net//g;
            $value =~ s/\s+//g;
            push @entity34_name, ($key.$value);
        }
