I would like format the my RSS feed content. Like embed some information with Description tag. I am creating Wordpress Rss feed and trying to create rss 2.0

<?xml version="1.0"?>
<rss version="2.0">
<channel>
<item>
<title>firstquestion</title>
<url>test-domain.com</url>
<description>This is some ifnormation on the description. The below are the answers for the new question</description></item>
</channel>
</rss>

Now, I want to format or further some table or information to be attached with special characters, even html tags formatting in the <description> ... How can I do that?

When I simply insert, it gives me an error?

Answer 1

You can have HTML inside the description element, but you have to encode it using htmlspecialchars .

$description = '<strong>Strong formatting</strong> or <em>emphasis</em>.';
$item = '<item>
           <title>firstquestion</title>
           <url>test-domain.com</url>
           <description>'.htmlspecialchars($description).'</description>
         </item>';

Answer 2

Use CDATA sections:

$description = '<strong>Strong formatting</strong> or <em>emphasis</em>.';
$item = '<item>
           <title>firstquestion</title>
           <url>test-domain.com</url>
           <description><![CDATA['.$description.']]></description>
         </item>';
