title: Format XML in racket
body: <p>I am working now with racket and XML creation files. To do so, I'm using the function:</p>
  
  <pre><code>(display-to-file
   ( SOME_XEXPR )
  (FILE_PATH)
  </code></pre>
  
  <p>And the XML looks like one bit mess. No newlines, identation or whitespaces, only one long line. How do I make the output look nicer?</p>
