Reference of hash (Perl)
Hi Perl users,

Could somebody help me to find the solution of my problem below.
Here is my data:
Code:
__DATA__
===================================================
NameOfipaddress                       ippair_1
propertiesx                           y
propertiesy                           x
ipAddress_1                           192.168.200.1
ipAddress_2                           192.168.200.2 
===================================================
NameOfipaddress                       ippair_2
propertiesx                           y
propertiesy                           x
ipAddress_1                           192.168.200.3
ipAddress_2                           192.168.200.4

Here is the expected result of the code:
Code:
__EXPECTED_RESULT__
FIRST_IP_PAIR
NameOfipaddress : ippair_1       
ipAddress_1     : 192.168.200.1  
ipAddress_2     : 192.168.200.2 

SECOND_IP_PAIR
NameOfipaddress : ippair_2
ipAddress_1     : 192.168.200.3
ipAddress_2     : 192.168.200.4

Here is my code and the unexpected result:

Code:
LINE:while (my $line = <FH>){
         chomp ($line);
         if ($line =~ m/^(NameOfipaddress)\s*(.*)/){
           push @{$datalog{'IP'}{$1}}, $2;
           next;
         }
         if ($line =~ m/^(ipAddress_1)\s*(.*)/){
           push @{$datalog{'IP'}{$1}}, $2;
           next;
         }
         if ($line =~ m/^(ipAddress_2)\s*(.*)/){
           push @{$datalog{'IP'}{$1}}, $2;
           redo LINE if ($line =~ m/^(NameOfipaddress)\s*(.*)/);
         }
     }
     
foreach my $key (sort keys %{$datalog{'IP'}}){
   print "$key: @{$datalog{'IP'}{$key}}";
   print "\n";
}     

__UNEXPECTED_RESULT(my code result)__
NameOfipaddress : ippair_1       ippair_2
ipAddress_1     : 192.168.200.1  192.168.200.3
ipAddress_2     : 192.168.200.2  192.168.200.4

aggregate-ios

AGGREGATE-IOS(1)					      General Commands Manual						  AGGREGATE-IOS(1)

NAME

       aggregate-ios - optimise a concatenated set of cisco/IOS prefix filters to help make them nice and short.

SYNOPSIS

       aggregate-ios <source_config >optimised_config

DESCRIPTION

       Takes  cisco IOS configuration on stdin, and optimises any prefix filters found using aggregate(1).  Optimised filters are produced on std-
       out.

OPTIONS

       None.

DIAGNOSTICS

       Any diagnostics produced by aggregate(1) are passed through on stderr.

EXAMPLES

       The following configuration fragment:

	 ip prefix-list AS65530 description Foo, Inc
	 ip prefix-list AS65530 permit 10.1.0.0/16
	 ip prefix-list AS65530 permit 10.2.0.0/16
	 ip prefix-list AS65530 permit 10.2.1.0/24
	 ip prefix-list AS65530 permit 10.3.0.0/16
	 ip prefix-list AS65531 description Bar.Com
	 ip prefix-list AS65531 seq 5 permit 192.168.1.0/24
	 ip prefix-list AS65531 seq 10 permit 192.168.2.0/24
	 ip prefix-list AS65531 seq 15 permit 192.168.0.0/19

       is optimised as follows:

	 ip prefix-list AS65530 permit 10.1.0.0/16 le 24
	 ip prefix-list AS65530 permit 10.2.0.0/15 le 24
	 ip prefix-list AS65531 permit 192.168.0.0/19 le 24

BUGS

       All those in aggregate(1) and then some :)
