FreshRSS is what I use and I can create my own feeds using X path, it's kinda great but too much to explain. I wrote a blog about it.

Don't know if this will achieve what you want, but I selfhost ChangeDetection.io to check if webpages have been updated, then subscribe to changedetection's RSS feed with FreshRSS.

I use and have contributed to RSShub. Now most of my 200 feeds come from there.

Hi,

Maybe look into rssparser.lisp

For Lemmy (which doesn't have a native RSS feed) I'm using Open RSS. It might be worth entering the sites you're trying to access into that, and see if it can produce feeds for you.

Fairly simple using Python locally with no need for a server: requests-html to get the website front page, then loop through the articles using feedgenerator to increment a feed object, then pipe it as XML to a file.

Obviously this is not simple at all but it does work. I have been consuming an RSS-free site by RSS every day for the last year. Provided you ensure theguid for each item is its URL, the RSS reader will keep track of what you have seen already, in order, which of course is the magic feature of RSS.

I use RSS Hub https://docs.rsshub.app/en/

I usually just resort to webscraping
