title: Spring Expression Language equivalent for \r, \n, \t etc
body: <p>I am using Spring Integration. I get a string (payload) like below:</p>
  
  <pre><code>&lt;Element&gt;
  &lt;Sub-Element&gt;5&lt;/Sub-Element&gt;
  &lt;/Element&gt;
  </code></pre>
  
  <p>I need to test if above string starts with <code>&lt;Element&gt;&lt;Sub-Element&gt;</code> which is actually  <code>&lt;Element&gt;\r\n &lt;Sub-Element&gt;.</code></p>
  
  <pre><code>&lt;int:recipient-list-router id="customRouter" input-channel="routingChannel"&gt;
      &lt;int:recipient channel="channel1" selector-expression="payload.startsWith('&amp;lt;Element&amp;gt;&amp;lt;Sub-Element&amp;gt;')"/&gt;
      &lt;int:recipient channel="channel2" selector-expression="!payload.startsWith('&amp;lt;Element&amp;gt;&amp;lt;Sub-Element&amp;gt;')"/&gt;
  &lt;/int:recipient-list-router&gt;
  </code></pre>
  
  <p>Ideally the first router should pass the test but in this case its failing. Can anyone help me finding out what is the SpEL equivalent of \r \n etc ?</p>
