tilak_sai has asked for the wisdom of the Perl Monks concerning the following question: 

sub Msg
{
    my $line = shift;
    my ($pf,$fixFields) =  split(/received:|Sent:/, $line);
    my %fixMsg;
    %fixMsg =  split(/[,=]/, $fixFields);
    @fixMsg{('_time_', '_mi_', '_fixsession_')} = (split(/\|/, $pf))[2
+,3,5];
    return \%fixMsg;
}

open file,"abc.txt"

while(<file>)
{
    $msg=pfUtils::Msg($_);
    foreach my $key (%{$msg})
    {
        if (!($key eq _mi_|$key eq _fixsession_|$key eq _time_|$msg->{
+$key} eq '')) 
        {
            printf "\n\t%20s  (%3d) = %s ", $code,$key,$value;
        }
    }
} 
close file;
