Real-World Use Cases

How to Validate an RSS Feed

• Use W3C Feed Validator: https://validator.w3.org/feed/
• Check for:
  • Proper XML structure
  • Date format compliance (pubDate)
  • Unique links and well-formed items

Best Practices for RSS Feeds

• ✔️ Include full title, link, and description for each <item>
• ✔️ Use pubDate in RFC 822 format (e.g., Fri, 24 May 2025 10:00:00 +0530)
• ✔️ Host RSS feed at a predictable URL like /rss.xml
• ✔️ Use CDATA if descriptions contain special characters (<, &)
• Don’t leave title or link empty—required by most readers
• Don’t use invalid or future-dated pubDate—can confuse parsers
