Hello everybody.
A couple weeks ago I stumbled upon this post by Derek Allard about how to implement an RSS feed in CI. The post itself is very self-explanatory, but what I didn't understand is the RSS feed code. Here it is:
Code:
<?php
echo '<?xml version="1.0" encoding="utf-8"?>' . "\n";
?>
<rss version="2.0"
xmlns:dc="http://purl.org/dc/elements/1.1/"
xmlns:sy="http://purl.org/rss/1.0/modules/syndication/"
xmlns:admin="http://webns.net/mvcb/"
xmlns:rdf="http://www.w3.org/1999/02/22-rdf-syntax-ns#"
xmlns:content="http://purl.org/rss/1.0/modules/content/">
<channel>
<title><?php echo $feed_name; ?></title>
<link><?php echo $feed_url; ?></link>
<description><?php echo $page_description; ?></description>
<dc:language><?php echo $page_language; ?></dc:language>
<dc:creator><?php echo $creator_email; ?></dc:creator>
<dc:rights>Copyright <?php echo gmdate("Y", time()); ?></dc:rights>
<admin:generatorAgent rdf:resource="http://www.codeigniter.com/" />
<?php foreach($posts->result() as $entry): ?>
<item>
<title><?php echo xml_convert($entry->post_title); ?></title>
<link><?php echo site_url('blog/post/' . $entry->url_title) ?></link>
<guid><?php echo site_url('blog/post/' . $entry->url_title) ?></guid>
<description><![CDATA[
<?= str_replace('/img/post_resources/', base_url() . 'img/post_resources/', $entry->post_body); ?>
]]></description>
<pubDate><?php echo date ('r', $entry->post_date);?></pubDate>
</item>
<?php endforeach; ?>
</channel></rss>Now it's the first time I actually try to build an RSS feed, so I don't know a thing about them. I did some research, and what I found is this code (and a couple other code similar code snippets):
Code:
<?xml version="1.0"?>
<rss version="2.0">

</rss>What I don't understand is what are the xmlns attributes in the rss opening tag and the dc: tags. I know this doesn't really have anything to do with CI itself, but can somebody (try) to explain to me what Derek's code means please?

Use SimplePie and You'll be happy :-)

As far as I know SimplePie is to retrieve RSS feeds and display/style them easily. What I want to do is create my own RSS feed. Additionally, SimplePie is not actively developped anymore.
Anyway, regardless of what I just wrote above, I don't want to rely on an external script for something as simple as RSS.
Can anyone else try to answer my question please?

it is a namespace, to tell browsers where to find the document type definitions ( ~ xml schema) so it can render the page properly. But you can remove them, it'll still work as a charm
