title: How Can i change the values of firstname and lastname
body: <p>I have a SOAP Service and it accepts the XML body below</p>
  <pre><code>&lt;?xml version=&quot;1.0&quot; encoding=&quot;UTF-8&quot;?&gt;
  &lt;body&gt;
     &lt;userDetails&gt;
        &lt;firstName&gt;${fname}&lt;/firstName&gt;
        &lt;lastName&gt;${lname}&lt;/lastName&gt;
     &lt;/userDetails&gt;
  &lt;/body&gt;
  </code></pre>
  <p>Now I want to replace the value in tag <code>&lt;firstName&gt;</code> and <code>&lt;lastName&gt;</code> dynamically while posting this XML Body.</p>
  <p>Is there a way to do that in RestAssured?</p>
