title: How to Loop through XML subnodes using PHP's simplexml
body: <p>OK, I'm having trouble looping through these sub-nodes.  For this example, I'll show you the code I am using to try to grab the Amenities from a Hotel Info feed.  The XML doesn't appear to be formatted great, and unfortunately I don't have control over that.  Here's my code.</p>
  
  <pre><code>$xml = simplexml_load_file("http://www.2-20.com/hotelRoomSearchDetails.cfm?pnum_hotel_seq_id=210&amp;pchr_room_type=STUDIO%22")
  $hotel_amenities = $xml-&gt;contentDataResults-&gt;hotelContent-&gt;hotelAmenities;
  
  foreach($hotel_amenities as $a){
      echo $a-&gt;amenity;
  }
  </code></pre>
  
  <p>It is only returning the first amenity however.</p>
