title: How I can transform a input characters to a different characters in a output? Datapower IBM
body: <p>In Datapower, I need to create services that receive input with "N" characters that must be transformed to other characters. For example:</p>
  
  <pre><code>Input: &lt;name&gt; Francisco&lt;/name&gt;
         &lt;lastname&gt;Pomodore&lt;/lastname&gt;
  
  Output: &lt;name&gt;aaaaaabb&lt;/name&gt;
          &lt;lastname&gt;tststs&lt;/lastname&gt;
  </code></pre>
  
  <p>I think that this problem is solved by using policy rules in the transform tool. However, I am not sure.</p>
