If you want a more object oriented approach you can modify App::Config like this 
#!/usr/bin/perl
#
#
use strict;
use warnings;

package AppConfig;

use 5.014;
use strict;
use warnings;
use autodie;
use Carp;
use Exporter qw(import);

# Module specific imports
use XML::Twig;

our $VERSION     = 1.00;
our @ISA         = qw(Exporter);
our @EXPORT_OK   = qw(getAppConfig);
our %EXPORT_TAGS = ( 'all' => \@EXPORT_OK, );

sub new {
    my $class         = shift;
    my $self          = {};
    my %passed_params = @_;
    croak "Please provide filename\n" unless (defined $passed_params{f
+ilename});
    $self->{filename}= $passed_params{filename};
    
    bless( $self, $class );
    return $self;
}

sub getAppConfig {
    my ($self) = @_;
    my ( %config, $twig, $root );
    $twig = XML::Twig->new();
    $twig->parsefile->( $self->{filename} );
    $root = $twig->root;

    $config{'ppSK'} =
      $root->first_child('pp')->first_child('ppSK')->text;

    return \%config;
}
# End.....
1;

And use the module like this
#!/usr/bin/perl

use 5.014;
use strict;
use warnings;
use autodie;
use AppConfig qw(:all);
use Data::Dumper;

my $app_config = AppConfig->new('filename' => '/home/john/tmp/config.x
+ml');

my %config=getAPPConfig();
