title: PHP simplexml_load_string does not load
body: <p>I'm trying to use simplexml_load_string like so:</p>
  
  <pre><code>$xml = '&lt;?xml version="1.0" encoding="utf-8"?&gt;
  &lt;soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/"&gt;
    &lt;soap:Body&gt;
      &lt;data_GetResult xmlns="http://api.source.com/"&gt;
        &lt;data_GetData&gt;
          &lt;value&gt;123456&lt;/value&gt;
          &lt;value&gt;789000&lt;/value&gt;
        &lt;/data_GetData&gt;
      &lt;/data_GetResult&gt;
    &lt;/soap:Body&gt;
  &lt;/soap:Envelope&gt;';      
  
  $results = simplexml_load_string($xml);
  print_r($results);
  </code></pre>
  
  <p>However, no results are returned, it simply shows:</p>
  
  <pre><code>SimpleXMLElement Object
  (
  )
  </code></pre>
  
  <p>I believe the xml is proper, I tested it in on-line validators. Thank you.</p>
