docs: Generate ``.wfind()`` call for HTMLElement.
  
      Args:
          use_dom (bool): Use ``dom`` as tag name. If ``False``, ``el`` is used.
          parameters (list): List of parameters for ``.wfind()``.
          index (int): Index of the item you want to get from ``.wfind()`` call.
          required (bool, default False): Use :func:`_required_idiom` to returned
                   data.
          notfoundmsg (str, default None): Message which will be used for
                      :func:`_required_idiom` if the item is not found.
  
      Returns:
          str: Python code.
  
      Live example::
          >>> print g._wfind_template(True, ["<xex>"], 3)
              el = dom.wfind('<xex>').childs
              # pick element from list
              el = el[3] if len(el) - 1 >= 3 else None
