How to add Doctype in XML document using DOM (JAVA)
Solution 1
You can construct the doctype with the DOM and set the doctype as an output property.
TransformerFactory transformerFactory = TransformerFactory.newInstance();
Transformer transformer = transformerFactory.newTransformer();
transformer.setOutputProperty(OutputKeys.INDENT, "yes");
transformer.setOutputProperty(OutputKeys.OMIT_XML_DECLARATION, "no");
transformer.setOutputProperty(OutputKeys.METHOD, "xml");
DOMImplementation domImpl = document.getImplementation();
DocumentType doctype = domImpl.createDocumentType("doctype",
"-//Oberon//YOUR PUBLIC DOCTYPE//EN",
"YOURDTD.dtd");
transformer.setOutputProperty(OutputKeys.DOCTYPE_PUBLIC, doctype.getPublicId());
transformer.setOutputProperty(OutputKeys.DOCTYPE_SYSTEM, doctype.getSystemId());
DOMSource source = new DOMSource(document);
StreamResult result = new StreamResult(new File(database));
transformer.transform(source, result);
Solution 2
If you get an instance of DOMImplementation
by invoking the getDOMImplementation()
method on the DocumentBuilder
, you can use the createDocument
method to create a new Document
with the specified doctype.
It also has a createDocumentType
method for creating a DocumentType
object
Refer to http://docs.oracle.com/javase/1.5.0/docs/api/org/w3c/dom/DOMImplementation.html and http://docs.oracle.com/javase/1.5.0/docs/api/javax/xml/parsers/DocumentBuilder.html for more info.

I have created a XML document using DOM in java. I am unable to add doctype. I want the doctype like this.
<!DOCTYPE IndInfo PUBLIC "EDAFileSomething" "EDAFileSomething_2_0.dtd">
Here is the document creation code.
DocumentBuilderFactory docFactory = DocumentBuilderFactory.newInstance(); DocumentBuilder docBuilder = docFactory.newDocumentBuilder(); Document doc = docBuilder.newDocument();
Here is the Transformer Object Code.
TransformerFactory transformerFactory = TransformerFactory.newInstance(); Transformer transformer = null; try { transformer = transformerFactory.newTransformer(); } catch (TransformerConfigurationException ex) { Logger.getLogger(Reader.class.getName()).log(Level.SEVERE, null, ex); } DOMSource source = new DOMSource(doc); try { StreamResult result = new StreamResult(System.out); transformer.transform(source, result); } catch (TransformerException ex) { Logger.getLogger(Reader.class.getName()).log(Level.SEVERE, null, ex); } System.out.println("File saved!");
