$xcp_request is a reference to a hash. The value of
$xcp_request->{attributes} is a reference to a hash. The value of
$xcp_request->{attributes}->{nameserver_list} is a reference to an
array.

Same thing only more deeply nested. You can use the Data::Dumper module
to display the contents.
$ perl -e'
use Data::Dumper;
$x->{a}->{b}->{c} = 1;
$x->{a}->{b}->{d} = 2;
$x->{a}->{e}->{c} = 3;
$x->{a}->{e}->{d} = 4;
print Dumper $x
'
$VAR1 = {
'a' => {
'e' => {
'c' => 3,
'd' => 4
},
'b' => {
'c' => 1,
'd' => 2
}
}
};
