body: <p>I am getting the following response from JMeter:</p>
  
  <pre><code>&lt;?xml version="1.0" encoding="UTF-8" standalone="yes"?&gt;
  &lt;CertificateResponse&gt;
      &lt;certificates&gt;
          &lt;certificate&gt;

              &lt;status&gt;2&lt;/status&gt;
              &lt;supportDSID&gt;0&lt;/supportDSID&gt;
              &lt;variableCard&gt;false&lt;/variableCard&gt;
              &lt;webOrderNumber&gt;M33764265&lt;/webOrderNumber&gt;
          &lt;/certificate&gt;
      &lt;/certificates&gt;
  &lt;/CertificateResponse&gt;
