You want preserveWhiteSpace = false and formatOutput = true (I know,
it's weird. But that's how it seems to work.) I think these options
also must be set directly after creating the new DOMDocument:

$xml = new DOMDocument;
$xml->preserveWhiteSpace = false;
$xml->formatOutput = true;

// do whatever you do

echo $xml->saveXML(); //output is indented
