Getting all selects with the same selected value in Prototype $$()?

How get all select with the same "selected value" in Prototype $$()?

Example: all select with "5" select value

<select name="first">
  <option value="">-- Selecione --</option>
  <option value="4">Auxiliar de vistoria</option>
  <option selected="selected" value="5">Examinador</option>
</select>

<select name="second">开发者_如何学Python
  <option value="">-- Selecione --</option>
  <option selected="selected" value="4">Auxiliar de vistoria</option>
  <option value="5">Examinador</option>
</select>

Thanks, Celso

Try:

$$('select:has(option:selected[value=5])')
