pdf download from RSS feed in DTPO

I liked this script to download a pdf from a Devonagent search and wondered if anyone had created a script to download pdf from RSS feeds in Devonthink or had other suggestions?

Do you have a feed that has links to PDFs?

All of my RSS feeds are current issue of scientific journal feeds. The links will sometimes take you to a summary of the article or sometimes to the full length article both of which will have a link to the pdf of the full article on the webpage.

Can I have a URL?

Here is one for the journal “Cell”
