title: Removing all <br> in a token in Gatling/Scala
body: <p>I have a http response and I save a token using regex and check.</p>
  
  <p>However the token contains a lot of html br (breaks) 's and I want to strip them and merge the token to be one string. </p>
  
  <p>I found this replace function for removing br's:</p>
  
  <pre><code>val str = "{$token}"
      str.replace("&lt;br/&gt;", "")
  </code></pre>
  
  <p>But how do I implement that in Gatling script? as .exec? or could I just say:</p>
  
  <pre><code>val str = "{$token}"
      str.replace("&lt;br/&gt;", "")
  </code></pre>
  
  <p>and then:</p>
  
  <pre><code>.exec(http("request_1")
      .post("/SS/?a=internett")
      .header("header_name", "${str}")
      .body(ElFileBody("request.xml"))
      .basicAuth("${y}","y"))
  </code></pre>
