in thread Split() first 3 elements of @array

Thanks for the suggestions. I have tried 2 ways and I still can't get some of the info. Lets assume the lines that I store at my @array are the following:

Device ID: switch1.Core-3750.abc.com
Entry address(es):
  IP address: 10.10.10.10
Platform: cisco WS-C3750G-12S,  Capabilities: Router Switch IGMP
Interface: GigabitEthernet1/0/28,  Port ID (outgoing port): GigabitEth
+ernet2/0/7
Holdtime : 145 sec

I can extract the switch name but I cannot sxtract the IP address for the switch for some reason

    foreach $Line ( @RouterOutput ) {
        if ( $Line =~ m/^Device / ) {
            @Data = split( ' ', $Line );
            $SwitchName = $Data[ 2 ] ;
            last ;
        }
        if ( $Line =~ m/^IP / ) {
            @Data = split( ' ', $Line );
            $SwitchIP = $Data[ 2 ] ;
            last ;
        }
    }

Try the following:

use Modern::Perl;

my @RouterOutput = <DATA>;
my $RouterOutput = join ' ', @RouterOutput;

my ( $SwitchName, $SwitchIP ) =
  $RouterOutput =~ /Device\s+ID:\s+([^\s]+).+IP\s+address:\s+([^\s]+)/
+s;

say "$SwitchName\n$SwitchIP";


__DATA__
Device ID: switch1.Core-3750.abc.com

The third line, with the IP address is indented: there is some whitespace at the beginning of the line, but your regular expression is looking for 'IP' at the beginning of the line: /^IP/. Change that to accept some leading whitespace and you should get a match: /^\s*IP/

[Kenosis]

use Modern::Perl;

use Modern::Perl;

say '  IP address: 10.10.10.10' =~ /IP\s+address:\s+([^\s]+)/;
say 'IP address: 10.10.10.10' =~ /IP\s+address:\s+([^\s]+)/;
say '  IP address: 10.10.10.10' =~ /^\s*IP\s+address:\s+([^\s]+)/;
say 'IP address: 10.10.10.10' =~ /^\s*IP\s+address:\s+([^\s]+)/;

Output:

10.10.10.10
10.10.10.10
10.10.10.10
10.10.10.10

Update: Ah! hmb104 was referring to using split, not the regex (which isn't attempting to match at the beginning of a line and is fully anchored w/o mentioning the spaces before "IP address:").
