Using the url.el package,

(defun www-get-page-title (url)
  (with-current-buffer (url-retrieve-synchronously url)
    (goto-char 0)
    (re-search-forward "<title>\\(.*\\)<[/]title>" nil t 1)
    (match-string 1)))

(www-get-page-title "http://www.emacswiki.org/emacs/Git";)
=> "EmacsWiki: Git"

hth,
