Pretty Print XML in Java

I got my solution from http://stackoverflow.com/questions/1264849/pretty-printing-output-from-javax-xml-transform-transformer-with-only-standard-ja

import javax.xml.transform.OutputKeys;

import javax.xml.transform.Source;
import javax.xml.transform.Transformer;
import javax.xml.transform.TransformerException;
import javax.xml.transform.TransformerFactory;
import javax.xml.transform.stream.StreamResult;
import javax.xml.transform.stream.StreamSource;

Transformer transformer = TransformerFactory.newInstance().newTransformer(); 
transformer.setOutputProperty("{http://xml.apache.org/xslt}indent-amount", "2");
transformer.setOutputProperty(OutputKeys.INDENT, "yes");

Source xmlInput = new StreamSource(new StringReader(xml));


StreamResult xmlOutput = new StreamResult(new StringWriter());
transformer.transform(xmlInput, xmlOutput);
System.out.println(xmlOutput.getWriter().toString());
