  <p>I want to change it with python 3 to be like this:</p>
  
  <pre><code>&lt;?xml version="1.0" encoding="UTF-8"?&gt;
  &lt;epp xmlns="urn:ietf:params:xml:ns:epp-1.0"&gt;
     &lt;command&gt;
        &lt;check&gt;
           &lt;check&gt;
              &lt;id&gt;ex61-irnic&lt;/id&gt;
              &lt;id&gt;ex999-irnic&lt;/id&gt;
              &lt;authInfo&gt;
                 &lt;pw&gt;1487441516170712&lt;/pw&gt;
              &lt;/authInfo&gt;
           &lt;/check&gt;
        &lt;/check&gt;
        &lt;clTRID&gt;TEST-12345&lt;/clTRID&gt;
