Add newlines into an XML file

Is there any way to pragmatically add in newline characters into an XML file? Lets say I have something like this:

docNode = com.mathworks.xml.XMLUtils.createDocument('root_element');
docRootNode = docNode.getDocumentElement;
docRootNode.setAttribute('attr_name','attr_value');
for i=1:5
    thisElement = docNode.createElement('child_node'); 
    thisElement.appendChild(docNode.createTextNode(sprintf('%i',i)));
    docRootNode.appendChild(thisElement);
end
docNode.appendChild(docNode.createComment('this is a comment'));
xmlFileName = ['tempname.xml'];
xmlwrite(xmlFileName,docNode);
type(xmlFileName);

This give the output:

<?xml version="1.0" encoding="utf-8"?>
<root_element attr_name="attr_value">
   <child_node>1</child_node>
   <child_node>2</child_node>
   <child_node>3</child_node>
   <child_node>4</child_node>
   <child_node>5</child_node>
</root_element><!--this is a comment-->

But I would like it to look like:

<?xml version="1.0" encoding="utf-8"?>
<root_element attr_name="attr_value">
   <child_node>1</child_node>

     <child_node>2</child_node>

     <child_node>3</child_node>

     <child_node>4</child_node>

     <child_node>5</child_node>
  </root_element><!--this is a comment-->

So is there any way that I can use docRootNode to add in newlines into the xml?

I think the answer is obvious, just add

docNode.appendChild(docNode.createTextNode(newline));

after creation of each "child_node".

Unfortunately, it doesn't add pretty formatting (if you need to indent following nodes, you'd need to add some spaces yourself in this text node.
