Hello all,
I want to define a capture template which pre-processes the head of the kill
ring with a sexp that takes a string as an argument:

(setq org-capture-templates
      (quote
       (("l" "Link" entry (file+headline "" "Links")
         "* \"%c\" %(get-page-title \"%c\")"))))

;; throws Bad url
(get-page-title "foo-bar")
;; works as expected
(get-page-title "http://orgmode.org/manual/Template-expansion.html")

(defun get-page-title (url)
  "Get title of web page, whose url can be found in the current line"
  ;; Get title of web page, with the help of functions in url.el
  (with-current-buffer (url-retrieve-synchronously url)
    ;; find title by grep the html code
    (goto-char 0)
    (re-search-forward "<title>\\([^<]*\\)</title>" nil t 1)
    (setq web_title_str (match-string 1))
    ;; find charset by grep the html code
    (goto-char 0)

    ;; find the charset, assume utf-8 otherwise
    (if (re-search-forward "charset=\\([-0-9a-zA-Z]*\\)" nil t 1)
        (setq coding_charset (downcase (match-string 1)))
      (setq coding_charset "utf-8")
    ;; decode the string of title.
    (setq web_title_str (decode-coding-string web_title_str (intern

coding_charset)))
    )
  (concat "[[" url "][" web_title_str "]]")
  ))

Please just ignore that I'm trying to parse XML with a regexp here.

get-page-title works when called from code but always returns bad url when
called from the capture template.
Is the problem the way I escape the string or is this just not the way the
sexp in capture are supposed to be used?

Regards,
Philipp
