How to generate a custom RSS feed from scratch programmatically

RSS is an XML feed, so to generate a valid RSS programmatically, you need to understand the RSS 2.0 Specification.

Lets first see how a RSS XML is structured.

The XML consists of two set of sections.


The purpose of Channel element is to define the overall website information. so, the following elements are required.

There are also other elements like image, category, generator and others but they are optional. Pick as you see it fit.


Here again elements like title, description and link are REQUIRED. Item provides the information about the individual posts that goes into the website. So, we need to create item per posts that our website contains. There is no limit to the number of item a channel can contain.


Once you publish a new blog post, you need to update both sitemap.xml and your rss.xml. Next add the reference to the rss on the index page - <link rel="alternate" type="application/rss+xml" href="" title="Example site">.

Schema Validation

Once you generate the RSS, you can validate it using Feed Validator, W3C Feed Validation or any other relevant RSS validators.
