title: pugiXML to locate child that has the same parents value
body: <p>So my XML is as followed</p>
  
  <pre><code>&lt;level1&gt;
      &lt;level2&gt;
            &lt;hero1&gt;
            &lt;/hero1&gt;
      &lt;/level2&gt;
      &lt;level2&gt;
            &lt;hero2&gt;
            &lt;/hero2&gt;
      &lt;/level2&gt;
  &lt;/level1&gt;
  </code></pre>
  
  <p>Now I want to access <code>hero2</code>, but when I do, suppose <code>doc</code> is my XML data</p>
  
  <p><code>
  doc.child("level1").child("level2").child("hero2")
  </code>
  It return <code>false</code>, which means that it couldn't locate my <code>hero2</code>. How could I find it?</p>
