如何去除dom生成的xml文件头的standalone="no" ，去掉后无换行

[baishuocs]

public void createXml(Document document,String fileName){
		
		TransformerFactory tf = TransformerFactory.newInstance(); 
		try { 
		Transformer transformer = tf.newTransformer(); 
		DOMSource source = new DOMSource(document); 
		transformer.setOutputProperty(OutputKeys.ENCODING, "gb2312"); 
		transformer.setOutputProperty(OutputKeys.INDENT, "yes"); 
		transformer.setOutputProperty(OutputKeys.STANDALONE, "yes");
		PrintWriter pw = new PrintWriter(new FileOutputStream(fileName)); 
		StreamResult result = new StreamResult(pw); 
		transformer.transform(source, result); 
		System.out.println("创建成功!"); 
		} catch (TransformerConfigurationException e) { 
		System.out.println(e.getMessage()); 
		} catch (IllegalArgumentException e) { 
		System.out.println(e.getMessage()); 
		} catch (FileNotFoundException e) { 
		System.out.println(e.getMessage()); 
		} catch (TransformerException e) { 
		System.out.println(e.getMessage()); 
		} 
	}

用这个可以去掉，但是就没有换行了，求解答！！
document.setXmlStandalone(true);

同问，遇到一样的问题

//设置换行 transformer.setOutputProperty(OutputKeys.INDENT, “yes”);

[花花花prometa小伙]

handler.startDocument(); AttributesImpl impl = new AttributesImpl(); // <department>标签前换行 String four = "\n"; handler.characters(four.toCharArray(),0,four.length()); handler.startElement("", "", "department", impl);

transformer.setOutputProperty(OutputKeys.DOCTYPE_PUBLIC,"yes");
transformer.setOutputProperty(OutputKeys.INDENT, "yes");

添加这2行就可以了。
