State -
  <Data>
    {% for access, args in pillar.get('disks', {}).items() -%}
    < "{{ args }}" />
    {% endfor -%}
</Data>

Output -
  <Data>
    < "J" />
    </Data>

I would like that the output will be -
  <Data>
    < "J" />
  </Data>

Please look on the indentation of the last line "</Data>"
