fastfeedparser 0.2.0

High performance RSS, Atom and RDF parser in Python

FastFeedParser

A high-performance RSS, Atom, and RDF feed parser for Python. FastFeedParser is designed to be fast, memory-efficient, and easy to use while providing comprehensive feed parsing capabilities.

Why FastFeedParser?

The main advantage of FastFeedParser over the traditional feedparser library is its lightweight design and exceptional performance - benchmarks show it's 10x-100x faster than feedparser while maintaining a familiar API. This dramatic speed improvement is achieved through:

• Efficient XML parsing using lxml
• Optimized memory usage
• Minimal dependencies
• Streamlined codebase focused on core functionality

FastFeedParser is used to effeciently process thousands of feeds for Kagi's Small Web initiative.

Features

• Fast parsing of RSS 2.0, Atom 1.0, and RDF/RSS 1.0 feeds
• Robust error handling and encoding detection
• Support for media content and enclosures
• Automatic date parsing with timezone handling
• Clean, Pythonic API similar to feedparser
• Comprehensive handling of feed metadata
• Support for various feed extensions (Media RSS, Dublin Core, etc.)

Installation

pip install fastfeedparser

Quick Start

import fastfeedparser

# Parse from URL
feed = fastfeedparser.parse('https://example.com/feed.xml')

# Parse from string
xml_content = '''<?xml version="1.0"?>
<rss version="2.0">
    <channel>
        <title>Example Feed</title>
        ...
    </channel>
</rss>'''
myfeed = fastfeedparser.parse(xml_content)

# Access feed global information
print(myfeed.feed.title)
print(myfeed.feed.link)

# Access feed entries
for entry in myfeed.entries:
    print(entry.title)
    print(entry.link)
    print(entry.published)

API Reference

Main Functions

• parse(source): Parse feed from a source that can be URL or a string

Feed Object Structure

The parser returns a FastFeedParserDict object with two main sections:

• feed: Contains feed-level metadata
• entries: List of feed entries

Each entry contains:

• title: Entry title
• link: Entry URL
• description: Entry description/summary
• published: Publication date
• author: Author information
• content: Full content
• media_content: Media attachments
• enclosures: Attached files

Requirements

• Python 3.7+
• httpx
• lxml
• parsedatetime
• python-dateutil
