title: Removing unwanted characters from username field using infopath
body: <p>Can anyone tell me how to remove unwanted characters from username field. 
  ex:  <code>i:0#.w|abcventures\sreekiran.k</code>  I need to remove the characters which are generated before <code>abcventures\sreekiran.k</code>.</p>
  
  <p>I have used <code>translate()</code> to eliminate those characters, but, it is removing <code>i</code> &amp; <code>w</code> characters also, from the username.</p>
