title: Drawing polygons with WKT - XML file using OpenLayers
body: <p>I have this XML file created with PHP and Mysql:</p>
  
  <p><img src="https://i.stack.imgur.com/dVhKt.png" alt="XML File"></p>
  
  <p>How can I use this to draw all the polygons using OpenLayers? I did some research and found examples with WKT, but in those examples they used just one polygon:</p>
  
  <pre><code>var feature = format.readFeature(
  'POLYGON((10.689697265625 -25.0927734375, 34.595947265625 ' +
  '-20.1708984375, 38.814697265625 -35.6396484375, 13.502197265625 ' +
  '-39.1552734375, 10.689697265625 -25.0927734375))');
  </code></pre>
  
  <p>I want to draw all the polygons to create a thematic map based on the "Area" data.</p>
