The JDOM Java library provides a formatter to pretty print an XML docment. Just read in an XML source then output the reformated contents.

SAXBuilder builder = new SAXBuilder();
Document doc = builder.build(new File(...));

XMLOutputter xo = new XMLOutputter(Format.getPrettyFormat());
String xmlPrettyContent = xo.outputString(doc);
System.out.println(xmlPrettyContent);

You can get an instance to the Formatter and tweak the settings to customize the output as needed.
