This list contains some of the better parsers for RSS and Atom feeds. I’ll try to keep it up-to-date.

RSS/Atom Parser for Java:

ROME

ROME is an set of open source Java tools for parsing, generating and publishing RSS and Atom feeds. The core ROME library depends only on the JDOM XML parser and supports parsing, generating and converting all of the popular RSS and Atom formats including RSS 0.90, RSS 0.91 Netscape, RSS 0.91 Userland, RSS 0.92, RSS 0.93, RSS 0.94, RSS 1.0, RSS 2.0, Atom 0.3, and Atom 1.0. You can parse to an RSS object model, an Atom object model or an abstract SyndFeed model that can model either family of formats.

• Able to extend functionality through Modules (see ROME Modules)

Jakarta FeedParser

Jakarta FeedParser is a Java RSS/Atom parser designed to elegantly support all versions of RSS (0.9, 0.91, 0.92, 1.0, and 2.0), Atom 0.5 (and future versions) as well as easy ad hoc extension and RSS 1.0 modules capability.

Eddie

Eddie is a liberal RSS and Atom feed parsing library for Java. It is a SAX based parser and as a result is capable of parsing a significant number of broken feeds.

Informa

With Informa we enable you with a harmonised view on a news channel object model. Both channels and news items do have metadata assigned, it does not make any difference from which channel format they were originally retrieved (RSS 0.9x, RSS 1.0 / RDF, RSS 2.0, Atom 0.3 and Atom 1.0).

RSS/Atom Parser for PHP:

SimplePie

SimplePie is a very fast and easy-to-use class, written in PHP, for reading RSS and Atom syndication feeds.

• Relatively active development
• Some better support for different namespaces would be nice.
• Contains good error-handling (e.g. can handle documents which are not well-formed).

MagpieRSS

MagpieRSS provides an XML-based (expat) RSS parser in PHP. MagpieRSS is compatible with RSS 0.9 through RSS 1.0. Also parses RSS 1.0’s modules, RSS 2.0, and Atom. (with a few exceptions)
