title: Parsing Entities in Cesium
body: <p>I have around 7k-8k placemarks in KML. I have to parse through each of the placemarks in cesium by importing the KML file. I have tried parsing through <code>EntityCollection.values</code> array but since not all the entities are placemarks, I find no other way of parsing through all placemark entities in Cesium.</p>
  
  <p>I would like to know the following:</p>
  
  <ol>
  <li>How are entities grouped in <code>EntityCollection.values</code>?</li>
  <li>Is there any other way to access all placemark entities which are created when a KML file is imported?</li>
  </ol>
  
  <p>I have tried to parse through the <code>EntityCollection.values</code> array and found out that only after an unspecified number of entities do the placemarks come.</p>
