XML Document to String?

Question

I've been fiddling with this for over twenty minutes and my Google-foo is failing me.

Let's say I have an XML Document created in Java (org.w3c.dom.Document):

DocumentBuilderFactory docFactory = DocumentBuilderFactory.newInstance(); DocumentBuilder docBuilder = docFactory.newDocumentBuilder(); Document document = docBuilder.newDocument();  Element rootElement = document.createElement("RootElement"); Element childElement = document.createElement("ChildElement"); childElement.appendChild(document.createTextNode("Child Text")); rootElement.appendChild(childElement);  document.appendChild(rootElement);  String documentConvertedToString = "?" // <---- How? 

How do I convert the document object into a text string?

Answer 1

public static String toString(Document doc) {     try {         StringWriter sw = new StringWriter();         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.transform(new DOMSource(doc), new StreamResult(sw));         return sw.toString();     } catch (Exception ex) {         throw new RuntimeException("Error converting to String", ex);     } }
