In the event that mirod has not managed to convert you to XML::Twig :-) then here's one code snippet to do what (I think) you want:

#!/usr/bin/perl

use strict;
use warnings;

use XML::Simple;

my $file = './Test.xml';
my $head = $ARGV[0] || 'Unknown';

my $map = XMLin($file, forcearray => ['header', 'act'], keyattr => { h
+eader => 'name'});

my $header = $map->{header}->{$head};

if($header) {
  foreach my $act ( @{$header->{act}} ) {
    print "act: $act\n";
  }
}
else {
  print "No match for '$head'\n";
}

Alternatively, you could iterate through the <header> items by using the keyattr option to turn off array folding:

my $map = XMLin($file, forcearray => ['header', 'act'], keyattr => {})
+;

my $headers = $map->{header};
foreach my $header (@$headers) {
  if($header->{name} eq $head) {
    foreach my $act ( @{$header->{act}} ) {
      print "act: $act\n";
    }
  }
}

By the way, your original code included this logic:

unless ($config = $xs1->XMLin($file, forcearray => 1)) {
    print "Could NOT read $file IN:$!\n";
    exit();
}

That won't actually work, since if XML::Simple can't parse the XML it will call 'die' rather than returning a false value. If you want to trap errors, you'd need to wrap the call to XMLin() in an eval block and check $@ afterwards.
