It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged. It was popularised in the 1960s with the release of Letraset sheets containing Lorem Ipsum passages, and more recently with desktop publishing software like Aldus PageMaker including versions of Lorem Ipsum.</p> <p></p>

推荐答案
希望此库对您有所帮助:
Hope you will find this library helpful:
rss-parser : https://github.com/bobby-brennan/rss-parser
-该库支持NodeJS和Web
这是浏览器中使用回调的示例:
Here's an example in the browser using callbacks:
<script src="/node_modules/rss-parser/dist/rss-parser.min.js"></script>
<script>
// Note: some RSS feeds can't be loaded in the browser due to CORS security.
// To get around this, you can use a proxy.
const CORS_PROXY = "https://cors-anywhere.herokuapp.com/"
let parser = new RSSParser();
parser.parseURL(CORS_PROXY + 'https://www.reddit.com/.rss', function(err, feed) {
console.log(feed.title);
feed.items.forEach(function(entry) {
console.log(entry.title + ':' + entry.link);
})
})
</script>
