langchain_community.document_loaders.rss.RSSFeedLoader¶

class langchain_community.document_loaders.rss.RSSFeedLoader(urls: Optional[Sequence[str]] = None, opml: Optional[str] = None, continue_on_failure: bool = True, show_progress_bar: bool = False, **newsloader_kwargs: Any)[source]¶

Load news articles from RSS feeds using Unstructured.

Parameters

  • urls (Optional[Sequence[str]]) – URLs for RSS feeds to load. Each articles in the feed is loaded into its own document.

  • opml (Optional[str]) – OPML file to load feed urls from. Only one of urls or opml should be provided. The value

  • string (can be a URL) –

  • string. (or OPML markup contents as byte or) –

  • continue_on_failure (bool) – If True, continue loading documents even if loading fails for a particular URL.

  • show_progress_bar (bool) – If True, use tqdm to show a loading progress bar. Requires tqdm to be installed, pip install tqdm.

  • **newsloader_kwargs (Any) – Any additional named arguments to pass to NewsURLLoader.

Example

from langchain_community.document_loaders import RSSFeedLoader

loader = RSSFeedLoader(
    urls=["<url-1>", "<url-2>"],
)
docs = loader.load()

The loader uses feedparser to parse RSS feeds. The feedparser library is not installed by default so you should install it if using this loader: https://pythonhosted.org/feedparser/

If you use OPML, you should also install listparser: https://pythonhosted.org/listparser/

Finally, newspaper is used to process each article: https://newspaper.readthedocs.io/en/latest/

Initialize with urls or OPML.
