Com.w3c.dom.Document without <? xml version = "1.0" encoding = "UTF-8" standalone = "no"?>

I am creating com.w3c.dom.Documentfrom Stringusing this code:

DocumentBuilderFactory docFactory = DocumentBuilderFactory.newInstance();
DocumentBuilder docBuilder = docFactory.newDocumentBuilder();
Document doc = docBuilder.parse(new InputSource(new StringReader("<a><b id="5"/></a>")));

When I System.out.println(xmlToString(document)), I get the following:

<?xml version="1.0" encoding="UTF-8" standalone="no"?><a><b id="5"/></a>

Everything is fine, but I do not want the XML to have an declaration <?xml version="1.0" encoding="UTF-8" standalone="no"?>, because I need to sign the private key and paste it into the soap envelope.

You can use Transformerand install OutputKeys.OMIT_XML_DECLARATIONup to "yes":

Transformer t = TransformerFactory.newInstance().newTransformer();
t.setOutputProperty(OutputKeys.OMIT_XML_DECLARATION, "yes");
StringWriter sw = new StringWriter();
t.transform(new DOMSource(doc), new StreamResult(sw));

Please note that you can also:

  • Use StreamSourceinstead DOMSourcefor direct transmission Stringto the transformer, if you really do not use it needed Document.
  • DOMResult StreamResult, Document.
