xml解析

Question

下面是写xml文件的方法,生成的.xml文件中有<?xml version="1.0" encoding="UTF-8" standalone="no"?>这样的标识,
如何能把standalone="no"这个属性去掉呢?

private void saveXml(Document document)
{
    try{     
          TransformerFactory   tf=TransformerFactory.newInstance();     
          Transformer   transformer=tf.newTransformer();     
          DOMSource   source=new   DOMSource(document);     
          transformer.setOutputProperty(OutputKeys.ENCODING,"UTF-8");    
          transformer.setOutputProperty(OutputKeys.INDENT,"yes");  
          PrintWriter   pw=new PrintWriter(new FileOutputStream(path));     
          StreamResult   result=new   StreamResult(pw);     
          transformer.transform(source,result);    
          //关闭流
          pw.close();
          }     
          catch(TransformerException   mye){     
          mye.printStackTrace();     
          }     
          catch(IOException   exp){     
          exp.printStackTrace();     
          }   
}

我在jdk1.5 下没有 new DOMSource(document) 只有new DOMSource();
用上面的代码生成的xml内容是没有standalone="no"的,如下:
[code="xml"]<?xml version="1.0" encoding="UTF-8"?>[/code]

中间加了这段
[code="java"]transformer.setOutputProperty(OutputKeys.STANDALONE, "no");[/code]
生成的xml文件内容才是有standalone="no"的,如下:
[code="xml"]<?xml version="1.0" encoding="UTF-8" standalone="no"?>[/code]
