title: Is there a way to select sibling nodes?
body: <p>For some performance reasons, I am trying to find a way to select only sibling nodes of the selected node.</p>
  <p>For example,</p>
  <pre><code>&lt;div id=&quot;outer&quot;&gt;
    &lt;div id=&quot;inner1&quot;&gt;&lt;/div&gt;
    &lt;div id=&quot;inner2&quot;&gt;&lt;/div&gt;
    &lt;div id=&quot;inner3&quot;&gt;&lt;/div&gt;
    &lt;div id=&quot;inner4&quot;&gt;&lt;/div&gt;
  &lt;/div&gt;
  </code></pre>
  <p>If I selected inner1 node, is there a way for me to access its siblings, <code>inner2-4</code> nodes?</p>
