title: How to select multiple nodes in different levels?
body: <p>Having this (simplified) XML:</p>
  
  <pre><code>&lt;?xml version="1.0" encoding="UTF-8"?&gt;
  &lt;kml&gt;
  &lt;Document&gt;
          &lt;Placemark&gt;
              &lt;name&gt;Poly 1&lt;/name&gt;
              &lt;Polygon&gt;
                          &lt;coordinates&gt;
                              -58.40844625779582,-34.60295278618136,0
                          &lt;/coordinates&gt;
              &lt;/Polygon&gt;
          &lt;/Placemark&gt;
          &lt;Placemark&gt;
              &lt;name&gt;Poly 2&lt;/name&gt;
              &lt;Polygon&gt;
                          &lt;coordinates&gt;
                              -58.40414334150432,-34.59992445476809,0
                          &lt;/coordinates&gt;
              &lt;/Polygon&gt;
          &lt;/Placemark&gt;
  &lt;/Document&gt;
  &lt;/kml&gt;
  </code></pre>
  
  <p>How can I select the name and coordinates of each Placemark?
  Right now I can select their name with the following XPath expression:</p>
  
  <pre><code>//Document//Placemark//name
  </code></pre>
  
  <p>How can I select both without any other data?</p>
