title: Find sibling node after specified node is found
body: <p>Consider the following very simplified example.</p>
  
  <pre><code>&lt;n&gt;&lt;/n&gt;
  &lt;k&gt;&lt;/k&gt;
  &lt;m&gt;&lt;/m&gt;
  &lt;k&gt;&lt;/k&gt;
  </code></pre>
  
  <p>How can I search for a first <code>k</code> sibling after <code>m</code> node? Basically, find some node and then continue searching from that node.</p>
