Thanks, Thamer. It works.

Below is the code snippet.

Well, I still have an encoding problem.
To get the title of "http://www.baidu.com", the title we get is displayed as
unrecognizable codes.

I have tried to encode it, in the way of "(setq web_title_str
(encode-coding-string  web_title_str 'utf-8-dos))", but it fails.
Since I am a newbie for emacs encoding, can you please help me to point what
the problem is?

;; -------------------------- separator --------------------------
(defun get-page-title()
  "Get title of web page, whose url can be found in current line"
  (interactive)
  ;; Get url from current line
  (copy-region-as-kill (re-search-backward "^") (re-search-forward "$"))
  (setq url (substring-no-properties (current-kill 0)))
  ;; Get title of web page, with the help of functions in url.el
  (with-current-buffer (url-retrieve-synchronously url)
    (goto-char 0)
    (re-search-forward "<title>\\(.*\\)<[/]title>" nil t 1)
    (setq web_title_str (match-string 1)))
    (setq web_title_str (encode-coding-string web_title_str 'utf-8-dos))
  ;; Insert the title in the next line
  (reindent-then-newline-and-indent)
  (insert web_title_str)
  )
