Hello, I have a list of items that can be described like this in an XML file: 
#dd.xml is a flie like this:

#<opt>
#    <Item> 
#        <User>a</User>
#        <Date>2003-11-27 18:00</Date>
#        <Title>Title </Title>
#        <Link>Link a 1</Link>
#        <Link>Link a 2</Link>
#        <IsVisible>1</IsVisible>
#    </Item> 
#    <Item> 
#        <User>b</User>
##        <Date>2003-11-27 19:00</Date>
#        <Title>Title b</Title>
#        <Link>Link b</Link>
#        <IsVisible>0</IsVisible>
#    </Item> 
#    <Item> 
#        <User>b</User>
##        <Date>2003-11-27 18:00</Date>
#        <Title>Title b</Title>
#        <Link>Link c</Link>
#        <IsVisible>0</IsVisible>
#    </Item> 
#</opt>

I am trying to load these items and then print them according to their date.
I came up with this code, that seems to work in preparing an array of hashes, but then I'm unable to make a "smart" sort in order to print the hashes according to the Date key value.
Thanks for any hint/correction.
R.

use strict;

my $list = new List;

my $file = './dd.xml';
$list->set_items($file);
$list->show();

package List;

use strict;
use XML::Simple;
use Data::Dumper;

sub new {
    my $class = shift;
    my $self  = {};
    bless($self, $class);

    $self->{Items} = ();

    return $self;
}

sub set_items {
    my $self = shift();
    my $file = shift();

# Here I load the xml file

    my %tmp = %{XMLin($file,noattr=>1)};
    $self->{Items} = $tmp{Item};
#    my $d = Dumper(\$self);
#    print "$d\n";
}

sub show {
    my $self = shift();
    my $q = shift();

# Here I build the array of hashes

    my @items = @{$self->{Items}};

#    my $d = Dumper(\@items);
#    print "$d\n";

    my $i;
    for $i (0..$#items) {
    print "-------------\n";
       my %hash = %{$items[$i]};
       my $d = Dumper(\%hash);
       print "$d\n";
#      my $date = $hash{Date};
    }
}

1;
