The article advises against using CDATA sections in RSS feeds due to complications with escaping the ']]>' sequence and reduced code readability. It recommends using standard XML character escaping instead, which provides a more uniform and maintainable solution. The author provides code examples and practical reasons why traditional escaping is preferable for RSS/Atom feeds.
Background
CDATA sections are commonly used in XML-based formats like RSS and Atom to escape blocks of text containing special characters, but they can introduce parsing complexities and maintenance issues. RSS (Really Simple Syndication) is a web feed standard used to publish frequently updated content such as blog posts and news headlines.
