SimpleXML is much easier.

 

<?php 

$xml_url = 'http://www.vn-zoom.com/external.php?type=RSS2&forumids=77';

$xml = new SimpleXMLElement( $xml_url, NULL, TRUE );

// Loop through <channel> -> <item>
foreach( $xml->channel->item as $item ) {
// Get the items in xmlns:content="http://purl.org/rss/1.0/modules/content/"
$content = $item->children('http://purl.org/rss/1.0/modules/content/');
// Echo content:encoded with a bunch of linebreaks.
echo $content->encoded."\n\n\n\n";
}

?>

Please Help me Fix my code. Because I use Loop "For" for this code.

I want to Get Each Value of Content by using Loop "for"
