title: Retrieve specific element before an other in jQuery
body: <p>I have a html like that :</p>
  
  <pre><code>&lt;fieldset&gt;
  &lt;legend&gt;Sondage&lt;/legend&gt;
  &lt;input type="hidden" value="formulaire_test/poll1352736068616/testencode" name="pollpost"&gt;
  &lt;p class="question"&gt;Q1&lt;/p&gt;
  &lt;p class="response"&gt;
  &lt;input id="R010101" type="radio" value="A" name="R0101"&gt;
  &lt;label for="R010101"&gt;R11&lt;/label&gt;
  &lt;/p&gt;
  &lt;p class="response"&gt;
  &lt;input id="R010102" type="radio" value="B" name="R0101"&gt;
  &lt;label for="R010102"&gt;r12&lt;/label&gt;
  &lt;/p&gt;
  &lt;p class="question"&gt;Q2&lt;/p&gt;
  &lt;p class="response"&gt;
  &lt;input id="R010201" type="radio" value="A" name="R0102"&gt;
  &lt;label for="R010201"&gt;r2&lt;/label&gt;
  &lt;/p&gt;
  &lt;p class="response"&gt;
  &lt;input id="R010202" type="radio" value="B" name="R0102"&gt;
  &lt;label for="R010202"&gt;r22&lt;/label&gt;
  &lt;/p&gt;
  &lt;p class="submit"&gt;
  &lt;input type="submit" value="Votez"&gt;
  &lt;/p&gt;
  &lt;/fieldset&gt;
  </code></pre>
  
  <p>I want with jQuery, for each <code>&lt;p class="response"&gt;</code> retrieve the <code>&lt;p class="question"&gt;</code> juste before.</p>
  
  <p>For example, if i have the response "r22" i want to retrieve Q2, if i have "r12" i want to retrieve Q1....</p>
  
  <p>Thanks :)</p>
