filter existing rss feed?

[cgoosen]

hello, this may be a silly question, but is there currently a way to filter an existing rss feed? chatgpt mentions an existing_feed route but I'm not seeing any info for it, eg:
https://rsshub.app/existing_feed?url=your_rss_feed_url&filter=keyword1|keyword2

thanks

Is this what you want?

[cgoosen]

Well, not entirely - I understand how to use the filters, but I'm looking to understand how to use them on an existing feed.

Suppose I have an RSS feed:
https://example.com/rss

I want to include only items mentioning "cybersecurity" or "threats" I can use "filter=cybersecurity|threats" for this, but how to generate the new feel url?

Is there a route to use specifically for existing RSS feeds?

So you have an existing RSS feed, and you want to pipe it through a certain middleware that filters its feeds?

I don't quite think RSSHub can handle that, unless you submit it as a route. On the other hand, check out this which I've come across ealier. I didn't try it myself though.

Yes, that's correct - I figured RSSHub would be a good way to do that.

Thanks for the info.
