What is the shortest way to pretty print a org.w3c.dom.Document to stdout?

Call printDocument(doc, System.out), where that method looks like this:

public static void printDocument(Document doc, OutputStream out) throws IOException, TransformerException {    TransformerFactory tf = TransformerFactory.newInstance();    Transformer transformer = tf.newTransformer();    transformer.setOutputProperty(OutputKeys.OMIT_XML_DECLARATION, "no");    transformer.setOutputProperty(OutputKeys.METHOD, "xml");    transformer.setOutputProperty(OutputKeys.INDENT, "yes");    transformer.setOutputProperty(OutputKeys.ENCODING, "UTF-8");    transformer.setOutputProperty("{http://xml.apache.org/xslt}indent-amount", "4");    transformer.transform(new DOMSource(doc),          new StreamResult(new OutputStreamWriter(out, "UTF-8")));}

(The indent-amount is optional, and might not work with your particular configuration)

How about:

OutputFormat format = new OutputFormat(doc);format.setIndenting(true);XMLSerializer serializer = new XMLSerializer(System.out, format);serializer.serialize(doc);

Try jcabi-xml with one liner:

String xml = new XMLDocument(document).toString();

This is the dependency you need:

<dependency>  <groupId>com.jcabi</groupId>  <artifactId>jcabi-xml</artifactId>  <version>0.14</version></dependency>
