title: jQuery: get parent tr for selected radio button
body: <p>I have the following HTML:</p>
  
  <pre><code>&lt;table id="MwDataList" class="data" width="100%" cellspacing="10px"&gt;
      ....
  
      &lt;td class="centerText" style="height: 56px;"&gt;
          &lt;input id="selectRadioButton" type="radio" name="selectRadioGroup"&gt;
      &lt;/td&gt;
  
      ....
  &lt;/table&gt;
  </code></pre>
  
  <p>In other words I have a table with few rows, in each row in the last cell I have a radio button.<br>
  How can I get <em>parent</em> row for selected radio button?</p>
  
  <p>What I have tried:</p>
  
  <pre><code>function getSelectedRowGuid() {
      var row = $("#MwDataList &gt; input:radio[@name=selectRadioGroup]:checked :parent tr");
      var guid = GetRowGuid(row);
      return guid;
  }
  </code></pre>
  
  <p>But it seems like this selector is incorrect.</p>
