title: Changing a time format of an xml file using a bash script
body: <p>I'm trying to change the formatting of a time in a file using a bash script. </p>
  
  <p>Current time format:
  08:05:00 </p>
  
  <p>Goal time format:
  8-05</p>
  
  <p>There are other timestamps I don't want to change in the file and every instance that I want to change is wrapped in xml:</p>
  
  <p>time="current time format" </p>
  
  <p>Can anyone help? </p>
