Writing xmlNodePtrs out with xmlSaveTree

I have a couple of questions on writing out an XML element
and its
children with xmlSaveTree:

First, is there any easy way to tell xmlSaveTree to write a
line break
after completing a node - so that things get written out
like

<foo>blah</foo>
<foo>bar</foo>

rather than

<foo>blah</foo><foo>bar</foo>

Or do I just need to write it myself - and if so, is there a
simple way to
use the xmlSaveCtxtPtr to write the break?

Second:
Is there any way to force a given indention level, so that I
can start
writing a document (i.e. write the xml, DOCTYPE, and root
node), then
repeatedly call xmlSaveTree to write the sub-elements
properly indented
within the root node?

 No, spaces are significant in XML, in general you can't
ignore or 
add them randomly.

 Make a text node with a single cariage return and serailize
it.

 Again, no, spaces are significant, and while there is
support for indentation
for whole document there is no provision for single nodes.
