Why XML::Smart module can't work

sanguine_perl has asked for the wisdom of the Perl Monks concerning the following question:

Hi, I am stuck by the problem of using XML::Smart module, it can't work. Recently, I want to use XML::Smart to parse the XML response, but i can't get any results,so i test the return as follows:

#!/usr/bin/perl

use XML::Smart;
use Data::Dumper;
use warnings;
use strict;

#open FILE1, 'run.xml' or die $!;

my $XML_1 = XML::Smart->new('run.xml');
my $ref = $XML_1->{product};
print $ref;
[download]

I expect to see the reference of response, but after running it

C:\Users\rchen4\Desktop\Perl_XML>perl script2.pl

C:\Users\rchen4\Desktop\Perl_XML>
[download]

no result. XML::Smart and Object::MultiType are all installed. Could someone be helpful?
