Using XML::LibXML (Fast!): 

use strict;
use warnings;

use XML::LibXML qw( );

my $xml = <<'__EOI__';
<?xml version = "1.0"?>

my $root = XML::LibXML->new->parse_string($xml)->documentElement;
my %data = map { $_->nodeName => $_->textContent }
   $root->findnodes('/*/*');

Using XML::Simple (a little less code in this situation, but doesn't work if the elements can have attributes): 

use strict;
use warnings;

use XML::Simple qw( :strict );

my $xml = <<'__EOI__';
<?xml version = "1.0"?>
<response>
  <custid>101010101</custid>
  <status>success</status>
  <responsecode>11</responsecode>
  <kf></kf>
  <cn>1111222233334444555</cn>
  <neta>7.00</neta>
  <prid>X111111111111111</prid>
  <ano>22222222</ano>
  <trxid>33333333</trxid>
  <description>Transfer Completed</description>
</response>
__EOI__

$XML::Simple::PREFERRED_PARSER = 'XML::Parser';  # Fastest backend
my $parser = XML::Simple->new( ForceArray => [], KeyAttr => {} );
my $data = $parser->XMLin($xml);

Update: Actually, looks like XML::Simple is not shorter. It's just slower and more fragile.
