Thanks to ShengHuo's nnrss-content-function, it was fairly easy to
cons up the following which kinda sorta lets you read the Heise
newsticker via nnrss. I'm interested in people who want to hack on
this.
(There is some flickering going on, and I would like to know why
there are \201 characters.)
(defun kai-nnrss-content-function (entry group article)
(let ((num (nth 0 entry))
(timestamp (nth 1 entry))
(url (nth 2 entry)))
(when (string-match "[hH]eise" group)
(message "Retrieving %s" url)
(let ((buf (url-retrieve-synchronously url))
(w3-display-same-buffer t)
parse)
(save-excursion
(set-buffer buf)
(goto-char (point-min))
(delete-region (point)
(search-forward "<HEISETEXT>"))
(insert "<html><body>")
(delete-region (search-forward "</HEISETEXT>")
(point-max))
(insert "</boxy></html>")
(setq parse (w3-parse-buffer (current-buffer)))
(erase-buffer)
(w3-draw-tree parse))
(insert-buffer buf)))))
(setq nnrss-content-function 'kai-nnrss-content-function)
As you can easily see, the method to grab the actual text of the news
item is very simple-minded. As you can also see, I don't have the
foggiest notion how to use the URL and W3 packages.
Does anyone have something similar for Tagesschau?

Here is a slightly improved version which does not display "\201ä"
instead of "ä" and so on. Also, you can use it to read the
newsticker of the Tagesschau, a German public TV news show.

But it's still quite hair-raising: first of all, regexp searching
does not strike me as the right way to find the relevant parts of the
page, and secondly, the explicit and unconditional re-encoding of the
W3 tree to Latin-1 smells really bad.

Do you think it makes sense to incorporate this into Gnus in some
way? (It needs to be polished up before that.)

Hm, what about the idea of separating moving targets like those rss
functions, nnslashdot, nnwarchive etc. from the main Gnus
distribution? It'll be helpful for users that don't want to upgrade
to Gnus development versions just for the sake of reading those news
services.
But I've no good idea how to implement this. Should there be a
subscription service (mailing list or some "Gnus news channel" within
Gnus itself)? What kind of information should be transferred (plain
Elisp files or some meta format to be defined)?
Cheers, Ray

It's clear that whoever set up the font colorings for most programming
modes has seen too many Peter Max posters, or did more acid than I did
in the 60's. (Charles R. Martin in gnu.emacs.help)

That is a good idea. But it seems nobody has stepped forward to do
the work.

It might be better to factor out the parsing code and to distribute
it. Maybe the parsing is done via regexes, then regexes could be
factored out. Or maybe the parsing is done via XPath, then XPath
queries could be factored out. Or a Lisp function, for full
generality.
