Kali ini kita coba menggunakan Curl dan fungsi SimpleXmlElement untuk melakukan parsing file format RSS atau xml. Sebelumnya beberapa fungsi parsing seperti simplexml_load_file juga berfungsi untuk parsing RSS.
Berikut ini contoh kode PHP Curl dan SimpleXmlElement yang digabung untuk parsing RSS mesin pencari Bing.
<?php
// Fungsi Curl
function curl($url){
$headers[] = "User-Agent:Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9.2.13) Gecko/20101203 Firefox/3.6.13";
$headers[] = "Accept:text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8";
$headers[] = "Accept-Language:en-us,en;q=0.5";
$headers[] = "Accept-Encoding:gzip,deflate";
$headers[] = "Accept-Charset:ISO-8859-1,utf-8;q=0.7,*;q=0.7";
$headers[] = "Keep-Alive:115";
$headers[] = "Connection:keep-alive";
$headers[] = "Cache-Control:max-age=0";
$curl = curl_init();
curl_setopt($curl, CURLOPT_URL, $url);
curl_setopt($curl, CURLOPT_FOLLOWLOCATION, 1);
curl_setopt($curl, CURLOPT_MAXREDIRS, 2);
curl_setopt($curl, CURLOPT_HTTPHEADER, $headers);
curl_setopt($curl, CURLOPT_ENCODING, "gzip");
curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($curl, CURLOPT_CONNECTTIMEOUT, 10);
curl_setopt($curl, CURLOPT_FOLLOWLOCATION, 1);
$data = curl_exec($curl);
curl_close($curl);
return $data;
}
$rssnull = curl('http://www.bing.com/search?q=melissa+joan+hart&count=10&format=rss');
//Fungsi SimpleXmlElement
$doc = new SimpleXmlElement($rssnull, LIBXML_NOCDATA);
function parseRSS($doc)
{
echo "<strong>".$doc->channel->title."</strong><br/>";
$cnt = count($doc->channel->item);
for($i=0; $i<$cnt; $i++)
{
$url = $doc->channel->item[$i]->link;
$title = $doc->channel->item[$i]->title;
$desc = $doc->channel->item[$i]->description;
echo '<a href="'.$url.'">'.$title.'</a><br/>'.$desc.'<br/>';
}
}
parseRSS($doc);
?>
Keterangan:
$doc->channel->title: Menampilkan kata kunci$url = $doc->channel->item[$i]->link;: Menampilkan tautan/link$title = $doc->channel->item[$i]->title;: Menampilkan judul/title$desc = $doc->channel->item[$i]->description;: Menampilkan deskripsi
