Args: urls: URLs for RSS feeds to load. Each articles in the feed is loaded into its own document. opml: OPML file to load feed urls from. Only one of urls or opml should be provided. The value can be a URL string, or OPML markup contents as byte or string. continue_on_failure: If True, continue loading documents even if loading fails for a particular URL. show_progress_bar: If True, use tqdm to show a loading progress bar. Requires tqdm to be installed, ``pip install tqdm``. **newsloader_kwargs: Any additional named arguments to pass to NewsURLLoader. Example: .. code-block:: python from langchain_community.document_loaders import RSSFeedLoader loader = RSSFeedLoader( urls=["", ""], ) 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/ NTFurlsopmlcontinue_on_failureshow_progress_barnewsloader_kwargsreturnc ~|du|dukrtd||_||_||_||_||_dS)zInitialize with urls or OPML.Nz;Provide either the urls or the opml argument, but not both.)
