Creating a moving and updating news aggregator list from RSS feeds involves several steps, including fetching RSS feeds, parsing the feed content, and then displaying it on a webpage. Here’s a simple example using Python with Flask for the backend and JavaScript with AJAX for frontend updates. We’ll also use the `feedparser` library to parse the RSS feeds. First, you’ll need to install Flask and feedparser if you haven’t already: “`bash pip install Flask feedparser “` Create a new directory for your project, and inside that directory, create these two files: `app.py` (for the server-side code) and `templates/news_aggregator.html` (for the client-side code). Here’s what you would put in each file: `app.py` (the server-side code): “`python from flask import Flask, render_template, jsonify import feedparser app = Flask(__name__) # List of RSS feed URLs FEED_URLS = [ ‘http://rss.cnn.com/rss/edition.rss’, ‘https://feeds.bbci.co.uk/news/rss.xml’, # Add more RSS feed URLs here ] @app.route(‘/’) def index(): return render_template(‘news_aggregator.html’) @app.route(‘/get_news’) def get_news(): news_items = [] for feed_url in FEED_URLS: feed = feedparser.parse(feed_url) for entry in feed.entries: news_items.append({ ‘title’: entry.title, ‘link’: entry.link, ‘published’: entry.published }) return jsonify(news_items) if __name__ == ‘__main__’: app.run(debug=True) “` `templates/news_aggregator.html` (the client-side code): “`html News Aggregator

“` What we have done here: – The Flask app serves an HTML page and provides a JSON endpoint `/get_news` that fetches and parses RSS feed data. – The HTML page uses AJAX to call the `/get_news` endpoint and update the news list without refreshing the page. – The AJAX call is set to repeat every 5 minutes using `setInterval`. – The page also refreshes every 5 minutes using the meta refresh tag, which is a fallback in case the AJAX call fails for some reason. Please note that this example is quite basic. There are no error checks for the RSS fetch, and it assumes that the feeds have a consistent structure. A production-ready application would need more robust error handling, caching, and possibly a more sophisticated front-end framework for a smoother user experience.
