Question ID: 720429
Is sofware available (free or for sale), to automatically fetch
content from RSS feeds on selected topices and store the stories on
the user's computer?  The RSS readers I've found only show lists of
short summaries with URL pointers which I have to click manually to
fetch the full story; and when the story is fetched, it isn't stored
on my PC, it is simply displayed.  So how do I effectively automate
the clicking and the storage of articles when retrieved on my PC? This
there an RSS reader that already does it?

I don't know of any RSS reader that offers such a feature. Part of the
difficulty with the automatic "storage of articles," as you call it,
is that web articles are not presented in any fixed format. A web link
in an RSS item points to a complicated document that consists of text
interspersed with many HTML tags, including references to images and
to other pages. The task of downloading the page and a reasonable
portion of its context is called scraping or slurping, and is quite
distinct from the task of managing RSS feeds.

Given a link from an RSS item to a New York Times article, for
example, what would you want to have downloaded and stored on your
hard disk? Just the human-readable text of the article, or all of the
HTML markup? If you must have the full HTML, would you want every
graphical element decorating the page to be downloaded to your
computer as well? If the article consists of multiple pages, are you
content to have only the first page downloaded and stored, or do you
need an artificial-intelligence algorithm to find the remaining pages
and slurp those too?
