Questions

Question #1

Do you know XML?

<?xml version='1.0' encoding='UTF-8'?>
<document>
    <foo>bar</foo>
</document>

Question #2

Do you know DOM?

var foo = document.getElementById('foo');
var bar = document.createElement('a');
foo.appendChild( bar );

Question #3

When you're developing an Ajax-based application,

Do you like to manipulate XML documents with such DOM methods?

Question #4

Do you like to play Nintendo Wii?

Wii Remote is a device ONLY for the Wii game console?

Why don't you like to manipulate DOM like playing Wii?

XML::TreePP

XML manipulation without Wiimote.

use XML::TreePP;
my $tpp = XML::TreePP->new();
my $url = "http://use.perl.org/index.rss";
my $tree = $tpp->parsehttp( GET => $url );
print $tree->{"rdf:RDF"}->{channel}->{title}, "\n";
print $tree->{"rdf:RDF"}->{channel}->{link}, "\n";

Device::Gainer module

use Device::Gainer;
my $opt = { host => '192.168.1.xx' };
my $gainer = Device::Gainer->new( %$opt );
$gainer->on_pressed( sub { print "PRESSED\n"; } );
$gainer->on_released( sub { print "RELEASED\n"; } );
$gainer->turn_on_led();
$gainer->turn_off_led();

POE::Component::Server::HTTP

use POE qw( Component::Server::HTTP );
use HTTP::Request::AsCGI;
use CGI;
my $aliases = POE::Component::Server::HTTP->new( %$conf );
POE::Kernel->run();
sub handler {
    my ($req, $res) = @_;
    my $ascgi = HTTP::Request::AsCGI->new($req)->setup;
    my $cgi = CGI->new();
    $res->content_type('text/plain');
    $res->content('Hello, World!');
    $res->code(RC_OK);
    return RC_OK;
}
