Your question isn't very clear.
Firstly do you just want to indent teh generated html file (for
readability) or do you want the browser to indent the result?


  Say I want the <NAME> to be indented by one one space in the first
  CAtegory and I want the <NAME> to be indented by 2 sapces in the second
  category and so on
