Format RSS and Atom Feed XML for Readability

Formatting RSS and Atom Feeds

RSS and Atom are XML-based syndication formats used to publish frequently updated content. Raw feed XML is often minified or poorly indented. Formatting makes the feed structure clear and easy to inspect.

Key Differences Between RSS and Atom

Feature	RSS 2.0	Atom
Root element	<rss>	<feed>
Item container	<item>	<entry>
Date format	RFC 822	ISO 8601
Content	<description>	<summary> / <content>
Namespace	None required	Required (xmlns)

Media Enclosures

RSS feeds for podcasts use <enclosure> elements to reference audio files:

<enclosure url="https://example.com/ep1.mp3"
           length="12345678"
           type="audio/mpeg" />

Extended Namespaces

Feeds often include namespace extensions like dc: (Dublin Core), content: (content:encoded for full HTML), itunes: (podcast metadata), and media: (Media RSS). Formatting keeps these namespace-prefixed elements clearly structured.
