Menampilkan RSS Feed menggunakan AJAX RSS Reader

RSS Reader digunakan untuk membaca RSS Feed suatu alamat situs web/blog. Contoh kode PHP sederhana berikut ini adalah salahsatu alternatif untuk menampilkan RSS Feed ke dalam tampilan HTML :

//get the q parameter from URL
$q=$_GET["q"];

//find out which feed was selected
if($q=="Google") {
  $xml=("http://news.google.com/news?ned=us&topic=h&output=rss");
} elseif($q=="NBC") {
  $xml=("http://rss.msnbc.msn.com/id/3032091/device/rss/rss.xml");
}

$xmlDoc = new DOMDocument();
$xmlDoc->load($xml);

//get elements from "<channel>"
$channel=$xmlDoc->getElementsByTagName('channel')->item(0);
$channel_title = $channel->getElementsByTagName('title')
->item(0)->childNodes->item(0)->nodeValue;
$channel_link = $channel->getElementsByTagName('link')
->item(0)->childNodes->item(0)->nodeValue;
$channel_desc = $channel->getElementsByTagName('description')
->item(0)->childNodes->item(0)->nodeValue;

//output elements from "<channel>"
echo("<p><a href='" . $channel_link
  . "'>" . $channel_title . "</a>");
echo("<br>");
echo($channel_desc . "</p>");

//get and output "<item>" elements
$x=$xmlDoc->getElementsByTagName('item');
for ($i=0; $i<=2; $i++) {
  $item_title=$x->item($i)->getElementsByTagName('title')
  ->item(0)->childNodes->item(0)->nodeValue;
  $item_link=$x->item($i)->getElementsByTagName('link')
  ->item(0)->childNodes->item(0)->nodeValue;
  $item_desc=$x->item($i)->getElementsByTagName('description')
  ->item(0)->childNodes->item(0)->nodeValue;
  echo ("<p><a href='" . $item_link
  . "'>" . $item_title . "</a>");
  echo ("<br>");
  echo ($item_desc . "</p>");
}
