Using xmlNewTextWriterTree with indentation

I am trying to use xmlNewTextWriterTree to add some elements
to a doc tree. I would like the new elements to be indented according
to their depth in the tree. But it seems the indentation level is starting
from 0.

Is there a different way for me to go about this?

I have:

<A>
  <B>
  </B>
</A>

I am using xmlNewTextWriterTree with the 'node' argument pointing
to the 'B' element.

I would like to end up with something like this:

<A>
  <B>
    <C>
      <D>
      </D>
    </C>
  </B>
<A>

But instead I get:

<A>
  <B><C>
  <D>
  </D>
<C></B>
</A>

Any pointers appreciated.
