How to get parsed output of org-eww-copy-for-org-mode ?

[stardiviner]

I try to get the parsed HTML content into Org format content for org capture
template.

#+begin_src emacs-lisp
(require 'org-eww)
(with-temp-buffer
  (insert html)
  (org-eww-copy-for-org-mode)
  ;; FIXME does not yank converted content, inserted original HTML instead.
  (current-kill 0)
  (org-yank))
#+end_src

But in upper code snippet, the ~current-kill~ or ~org-yank~ (or ~yank~) can't 
get the
output. I try to use *advice-add*, but I don't know which advice combinator can
archive the purpose that get the parsed output of ~org-eww-copy-for-org-mode~ 
and
save it somewhere like variable or register. So that I can yank in capture
buffer again.
