First, that's not valid XML, the &'s are not entity encoded, and the namespaces are not declared, but I assume you really do have valid XML otherwise XML::Simple could not parse it. Whatever you get back from XML::Simple, you can use Data::Dumper to see the structure of the data it returns. Or you can only process the things you want to process the way you want to process them with something like XML::Rules:

use XML::Rules;

my @rules = (
  'm:properties' => sub {
    my $p = $_[1];
    print "Title      : $p->{'d:Title'}\n";
    print "Description: $p->{'d:Description'}\n";
  },
  _default => 'content',
);

my $xr = XML::Rules->new(
  rules => \@rules,
);

$xr->parse($xml);
