  Check
     http://bugzilla.gnome.org/show_bug.cgi?id=75244

You can use xmllint --format

paphio:~/XML -> cat tst.xml 
<doc><a>
<b><c>foo
</c>

</b>
</a></doc>
paphio:~/XML -> ./xmllint --format tst.xml 
<?xml version="1.0"?>
<doc>
  <a>
    <b>
      <c>foo
</c>
    </b>
  </a>
</doc>
paphio:~/XML -> 
 
At the C level you need to either:
    set
      xmlIndentTreeOutput = 1;
    or call
      xmlKeepBlanksDefault(0);

to have indentation and not just line break added.
Note also that libxml2 will not indent or add linebreak within elements
which are mixed content.
