Atom, RSS and JSON feed parser for Python 3.

Quickstart

Install Atoma with pip::

pip install atoma

Load and parse an Atom XML file:

.. code:: python

>>> import atoma
>>> feed = atoma.parse_rss_file('rss-feed.xml')
>>> feed.description
'The blog relating the daily life of web agency developers'
>>> len(feed.items)
5

Parsing feeds from the Internet is easy as well:

.. code:: python

>>> import atoma, requests
>>> response = requests.get('http://lucumr.pocoo.org/feed.atom')
>>> feed = atoma.parse_atom_bytes(response.content)
>>> feed.title.value
"Armin Ronacher's Thoughts and Writings"

Features

• RSS 2.0 - RSS 2.0 Specification <http://cyber.harvard.edu/rss/rss.html>_
• Atom Syndication Format v1 - RFC4287 <https://tools.ietf.org/html/rfc4287>_
• JSON Feed v1 - JSON Feed specification <https://jsonfeed.org/version/1>_
• OPML 2.0, to share lists of feeds - OPML 2.0 <http://dev.opml.org/spec2.html>_
• Typed: feeds decomposed into meaningful Python objects
• Secure: uses defusedxml to load untrusted feeds
• Compatible with Python 3.6+

Security warning

If you use this library to display content from feeds in a web page, you NEED to clean the HTML contained in the feeds to prevent Cross-site scripting (XSS) <https://en.wikipedia.org/wiki/Cross-site_scripting>. The bleach <https://github.com/mozilla/bleach> library is recommended for cleaning feeds.

Useful Resources

To use this library a basic understanding of feeds is required. For Atom, the Introduction to Atom <https://validator.w3.org/feed/docs/atom.html>_ is a must read. The RFC 4287 <https://tools.ietf.org/html/rfc4287>_ can help lift some ambiguities. Finally the feed validator <https://validator.w3.org/feed/>_ is great to test hand-crafted feeds.

For RSS, the RSS specification <http://cyber.harvard.edu/rss/rss.html>_ and rssboard.org <http://www.rssboard.org>_ have a ton of information and examples.

For OPML, the OPML specification <http://dev.opml.org/spec2.html#subscriptionLists>_ has a paragraph dedicated to its usage for syndication

Non-implemented Features

Some seldom used features are not implemented:

• XML signature and encryption
• Some Atom and RSS extensions
• Atom content other than text, html and xhtml
