parseXML adding line break

parseXML adding line break

Im' trying to do a similar thing like this:

The result ends up like this:
  1. <?xml version="1.0" encoding="utf-8"?><root><obj someAttr="100500">some text</obj></root>

But what I really want is having line breaks like this:
  1. <?xml version="1.0" encoding="utf-8"?>
  2. <root>
  3.       <obj someAttr="100500">some text</obj>
  4. </root>

Is that achievable? If so, how can it be done?
