Hallo People. I have one question about HTTP PUT Request with separate values in csv. In this code example I compare hashes, but for my PUT and POST request I need separate values.
For example, I have two output files from different Systems:

output1.csv (name, ip) - Primary system

TEST_1,10.56.7.80
TEST_3,10.66.78.10
TEST_4,10.66.81.9
TEST_2,10.67.9.12

my ($file_1, $file_2) = ('output1.csv', 'output2.csv');

open my $fh, '<', $file_1  or die "Can't open $file_1: $!";
my %first = map { chomp; split /\s*,\s*/ } <$fh>;            



open    $fh, '<', $file_2  or die "Can't open $file_2: $!";
my %second = map { chomp; (split /\s*,\s*/)[1,2] } <$fh>;



#Create a user agent object
my $ua = LWP::UserAgent->new(ssl_opts=> {
    SSL_verify_mode => SSL_VERIFY_NONE(),
    verify_hostname => 0,
});

foreach my $name (sort keys %first) {
    if (not exists $second{$name}) {
        say "Devices should be added: $name";
        next;
    }

    if ($first{$name} eq $second{$name}) {
        say "Match found $name, $first{$name}";
    } else {
        say "UPDATE need be done for $second{$name}";

Till this place my code works. I compare my hushes and I see messenges in shell.
Now I want to make PUT (Update) request for these devices, those are nor identic

Idee ist to open separate both of files and to add to Secondary the ipaddress or names from Primary System

To make it this way I Need to take ip(or name) from the device from output1.csv and to make PUT request to secondary System (Update)

  open ( my $input_1, '<', 'output1.csv' ) or die $!;
  while ( <$input_1> ) {
    chomp;
    my ($name_1, $ip_1) = split /,/;

(my $id, $first{$name}, $second{$name}) = split /,/;
    my $xml = XML::Twig -> new -> parsefile ( 'example.xml' ); 
    $xml ->set_pretty_print('indented_a');

    open ( my $input_2, '<', 'output2.csv' ) or die $!;
    while ( <$input_2> ) {
     chomp;

     $xml -> root -> set_att('name', $name_1);
     $xml -> get_xpath('//ipaddress',0) -> set_text($ip_1);
     my $uri="https://hostname:9060/ers/config/networkdevice/$id";
     my $req = HTTP::Request->new('PUT', $uri,
     [Accept=>'application/vnd.com.cisco.ise.network.networkdevice.1.1
++xml',
     Content_Type=>'application/vnd.com.cisco.ise.network.networkdevic
+e.1.1+xml; charset=utf-8'], $xml->sprint);

      $req->content($xml->sprint);
      $req->authorization_basic("user", "user");

      #Pass request to the user agent and get a response back
  #Pass request to the user agent and get a response back
       my $res = $ua->request($req);
      #Check the outcome of the response
      if ($res->is_success) {
          print $res->status_line, "\n";
          } else {
          print $res->status_line, "\n";
                  }
                             }
         }

}
