Te expongo una forma sencilla de crear RSS

Código PHP:

<?php
class rss2 extends DOMDocument {
    private $channel;
    public function __construct($title, $link, $description) {
        parent::__construct();
        $this->formatOutput = true;
        $root = $this->appendChild($this->createElement('rss'));
        $root->setAttribute('version', '2.0');
        $channel= $root->appendChild($this->createElement('channel'));
        $channel->appendChild($this->createElement('title', $title));
        $channel->appendChild($this->createElement('link', $link));
        $channel->appendChild($this->createElement('description', $description));
        $this->channel = $channel;
    }
 
    public function addItem($title, $link, $description) {
        $item = $this->createElement('item');
        $item->appendChild($this->createElement('title', $title));
        $item->appendChild($this->createElement('link', $link));
        $item->appendChild($this->createElement('description', $description));
        $this->channel->appendChild($item);
    }
}
 
$rss = new rss2('Foros del web', 'http://www.forosdelweb.com/f18/','Foro de PHP');
$rss->addItem('foo', 'http://www.example.org/foo','foo Descripción');
$rss->addItem('bar', 'http://www.example.org/bar','bar Descripción');
echo $rss->saveXML();
 

Esto escribirá

Código XML:

<?xml version="1.0"?>
<rss version="2.0">
  <channel>
    <title>Foros del web</title>
    <link>http://www.forosdelweb.com/f18/</link>
    <description>Foro de PHP</description>
    <item>
      <title>foo</title>
      <link>http://www.example.org/foo</link>
      <description>foo Descripci</description>
    </item>
    <item>
      <title>bar</title>
      <link>http://www.example.org/bar</link>
      <description>bar Descripci</description>
    </item>
  </channel>
</rss>
