You can use the  following classes:
org.apache.xml.serialize.XMLSerializer;
org.apache.xml.serialize.DOMSerializer;

Here is an extract of some code I use to perform this task:


  OutputFormat outputFormat = new OutputFormat();
  outputFormat.setMethod(Method.XML);
  outputFormat.setIndenting(true);
  outputFormat.setIndent(4);
        
  ByteArrayOutputStream baos = new ByteArrayOutputStream();
  XMLSerializer xmlSerializer = new XMLSerializer(
     baos, outputFormat);
  DOMSerializer domSerializer = xmlSerializer.asDOMSerializer();
  domSerializer.serialize(doc);
  byte[] data = baos.toByteArray();

You can then write the byte array to a file. 

I specifically wanted a byte array for other reasons; because you only
want to write to a file, you might be able to pass a FileOutputStream to
the XMLSerializer or similar.
