title: How to find specific value in MongoDB-C driver
body: <p>When my structure looks like this: </p>
  
  <pre><code>X: {
     Y: "blabla"
  }
  </code></pre>
  
  <p>So I use the function "bson_iter_find_descendant(&amp;iter, "<strong>X.Y</strong>", &amp;desc)" to recover my data. But how to retrieve the values of "<strong>X.Y</strong>", "<strong>X.Z</strong>"... when my structure looks like this: </p>
  
  <pre><code>X: [
     {
        Y: "blihblih"
     },
     {
        Z: "bloublou"
     }
  ]
  </code></pre>
  
  <p>Note that I use the latest version of MongoDB-C Driver ...</p>
  
  <p>Thank you in advance!</p>
