only posting (added) or (into)

[geezfools]

Is there any means possible of ONLY notifying of the actual new items? I'm monitoring a few different sites for new items and then sharing those items to myself and a few friends on discord. The problem I'm having is that say a site adds two new products, I get the following.
(changed) "https://www.onenewitem.com/001"
(into) "https://www.onenewitem.com/002",
(into) "https://www.onenewitem.com/003"

I don't care about "https://www.onenewitem.com/001" because it was already posted to discord a couple of days ago. So I'm trying to figure out if there is a way to only notify about the actual new stuff.

I'm using a mix of xpath or json to monitor these sites. Regardless of combinations I choose for text filtering, I still get what's changed as well as what's new. I'm a noob when it comes to this stuff, but have been getting better with the use of chatgpt and claude, but this one continues to elude me.
