Java DOM XML file creation – there are no tabs or spaces in the output file

I've checked the post on stack overflow, but it doesn't seem to help

What is this:

// write the content into xml file
        TransformerFactory transformerFactory = TransformerFactory.newInstance();
        transformerFactory.setAttribute("indent-number",2);
        Transformer transformer = transformerFactory.newTransformer();
        transformer.setOutputProperty(OutputKeys.INDENT,"yes");

        DOMSource source = new DOMSource(xmlDoc);
        StreamResult result =  new StreamResult(new File("C:\\testing.xml"));
        transformer.transform(source,result);

This is the output I get:

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<Satellite SatelliteName="" XmlFiLeversion="">
<test0>
<test1>
<test2>
<test3>
<test4>
<test5>
<test6>
<test7>
<test8>
<test9/>
</test8>
</test7>
</test6>
</test5>
</test4>
</test3>
</test2>
</test1>
</test0>
</Satellite>

No labels or spaces

I set the indent number because there may be an error in Java, and I activated outputkeys INDENT.

Any other ideas?

Edit 1 (after adarshr repair):

I have a space now Only the first satellite entry is in the first row and should not be in the first row

<?xml version="1.0" encoding="UTF-8"?><Satellite SatelliteName="" XmlFiLeversion="">
  <test0>
    <test1>
      <test2>
        <test3>
          <test4>
            <test5>
              <test6>
                <test7>
                  <test8>
                    <test9>blah</test9>
                  </test8>
                </test7>
              </test6>
            </test5>
          </test4>
        </test3>
      </test2>
    </test1>
  </test0>
  <sdjklhewlkr/>
</Satellite>

Edit 2:

So the current state is that I now have spaces, but I don't have line breaks after the XML declaration How can I solve this problem?

Solution

Try to set the indent amount as follows:

transformer.setOutputProperty("{http://xml.apache.org/xslt}indent-amount","2");
