You can do this with shr alone.  A quick hack:

(defun shr-render-region (begin end &optional buffer)
  "Display the HTML rendering of the region between BEGIN and END."
  (interactive "r")
  (unless (fboundp 'libxml-parse-html-region)
    (error "This function requires Emacs to be compiled with libxml2"))
  (with-current-buffer (or buffer (current-buffer))
    (let ((dom (libxml-parse-html-region begin end)))
      (kill-region begin end)
      (goto-char begin)
      (shr-insert-document dom))))
