To fetch URL, extract <title> element?

[Jean Louis <bugs@gnu.support>]

What is the standard built-in way to fetch the http[s] URL?

I need to get string to parse <title> and I think something like this
below:

(setq a
      (with-temp-buffer
	(url-retrieve "https://www.gnu.org" 'identity)
	(buffer-string)))


When researching `eww' I find this function here, which is chunk that
makes sure of parsing and punny code in the URL. I do not find it
useful as I cannot easily fetch URL without thinking of those details.

;;;###autoload
(defun eww (url &optional arg buffer)
  "Fetch URL and render the page.
If the input doesn't look like an URL or a domain name, the
word(s) will be searched for via `eww-search-prefix'.

If called with a prefix ARG, use a new buffer instead of reusing
the default EWW buffer.

If BUFFER, the data to be rendered is in that buffer.  In that
case, this function doesn't actually fetch URL.  BUFFER will be
killed after rendering."
  (interactive
   (let ((uris (eww-suggested-uris)))
     (list (read-string (format-prompt "Enter URL or keywords"
                                       (and uris (car uris)))
                        nil 'eww-prompt-history uris)
           (prefix-numeric-value current-prefix-arg))))
  (setq url (eww--dwim-expand-url url))
  (pop-to-buffer-same-window
   (cond
    ((eq arg 4)
     (generate-new-buffer "*eww*"))
    ((eq major-mode 'eww-mode)
     (current-buffer))
    (t
     (get-buffer-create "*eww*"))))
  (eww-setup-buffer)
  ;; Check whether the domain only uses "Highly Restricted" Unicode
  ;; IDNA characters.  If not, transform to punycode to indicate that

  (let ((parsed (url-generic-parse-url url)))
