Write xml file with indentation

We are going to see how can transform an org.w3c.dom.Document object in an xml file.

public void writeXmlFile(Document doc, String filename)
			throws TransformerFactoryConfigurationError, TransformerException {
		Source source = new DOMSource(doc);
		// prepare output
		File xmlFile = new File( filename);
		Result result = new StreamResult(xmlFile);

		// write file
		Transformer transform = TransformerFactory.newInstance()
				.newTransformer();
                //indent the xml content
		transform.setOutputProperty(OutputKeys.INDENT, "yes");
		transform.transform(source, result);
	}

The indentation is done with this line by setting to yes the property “OutputKeys.INDENT”

//indent the xml content
transform.setOutputProperty(OutputKeys.INDENT, "yes");
