I have a data file: 

config system interface
    edit "dmz"
        set vdom "root"
        set ip 192.18.254.1 255.255.254.0
        set allowaccess ping fgfm
        set type physical
        set alias "Guest-Wlan"
    next
    edit "wan2"
        set vdom "test"
        set ip 10.4.254.198 255.255.255.252
        set allowaccess ping https ssh snmp
        set type physical
        set alias "To MON ospf int"
    next
    edit "wan1"
        set vdom "root"
        set ip 1.1.1.1 255.255.255.252
        set allowaccess ping https
        set type physical
        set alias "To Internet"
    next
    edit "modem"
        set vdom "root"
        set mode pppoe
        set allowaccess fgfm
        set type physical
    next
    edit "ssl.root"
        set vdom "root"
        set type tunnel
    next
    edit "ssl.MyRealm"
        set vdom "MyRealm"
        set type tunnel
    next
    edit "internal1"
        set vdom "root"
        set ip 10.1.16.3 255.255.255.0
        set allowaccess ping https ssh snmp fgfm
        set type physical
        set alias "To MON Internal "
    next
  edit "internal2"
        set vdom "MyRealm"
        set dhcp-relay-service enable
        set dhcp-relay-ip "192.168.1.1"
        set ip 192.168.2.1 255.255.254.0
        set allowaccess ping https ssh snmp fgfm
        set type physical
        set alias "To MINE"
    next
    edit "VPN-Dial"
        set vdom "root"
        set type tunnel
        set interface "wan1"
    next
end

I want to be able to parse into say, the "Internal1" section, and slurp up the ip. I have written the following code, but cannot get it to match what I need using multiline and push: 
#!/usr/bin/perl -w
use Switch;
my $num_Args=$#ARGV +1;
if ($num_Args !=2) {
  print "\nUsage: Argument 1 is the filename to parse, Argument 2 is t
+he Management Ip address\n";
  exit;
}
my $filename = $ARGV[0];
my $ipaddr= $ARGV[1];
open (my $fh, $filename)
  or die "Could not open file '$filename' $!\n";

while (my $row = <$fh>) {
  chomp $row;
  switch ($row){
    #print $row;
    case /config system interface/      {
                                         <>;
                     if (/edit \"internal1\"/) {
                       print "Number was 1\n";
                       $grabbing=1;
                     }
                     elsif ( /^$/ ) {
                       $grabbing = 0;
                     }
                     if ($grabbing ) {
                       push @grabbed, @_;
                     }
                     
                                         
                     
                    }
  }
  print @grabbed;
}

So by the end it would be nice to have a hash table of interfaces and their ip addresses, or even more simply a bunch of variables: 10.1.16.3 $internal1="10.1.16.3" $wan="10.4.254.198" Etc. I want to compare them to the entered string in @argv, and then do some stuff. Any ideas, or is my 'push' idea totally wrong?
