I have an XML file that I parsed using a DOMParser and now have a document object. Now I want to write that document object to an XML file and have it be formatted nicely (tabs, line feeds, etc). I accomplished what I needed by using a Transformer. I'm interested in what people think of the following two approaches and using one versus the other.

The first approach uses . This approach was presented in "Java and XML" by McLaughlin. You can download the code from the chapter 5 eamples at http://newinstance.com/writing/javaxml2_examples/javaxml2_ch05.zip
It requires handling each node and seemed especially cumbersome after I found out about the next approach.

In the second approach I use and can write the document to file with the following code (based on http://java.sun.com/j2ee/1.4/docs/tutorial/doc/JAXPXSLT4.html):

			

			...
			

			...
			

			// Use a Transformer for output
			

			TransformerFactory tFactory = TransformerFactory.newInstance();
			

			Transformer transformer = tFactory.newTransformer();
			

			

			DOMSource source = new DOMSource(doc);
			

			FileWriter outFile = new FileWriter(outFileName);
			

			

			StreamResult result = new StreamResult(outFile);
			

			transformer.transform(source, result);
			

			...
