[英]Writing to XML file by java not working
I am trying to create node named Log which contains these tags date,message,type. 我正在尝试创建名为Log的节点,其中包含这些标记的日期,消息,类型。 I have written a function that does my job.
我编写了一个可以完成工作的函数。 Somehow it doesn't generate any exceptions, but still it is not working.
它以某种方式不会生成任何异常,但是仍然无法正常工作。 I am not getting that tag.
我没有那个标签。 Can anyine tell me where I have gone wrong?
有谁能告诉我哪里出了问题?
void writeToXML(String date,String message,String type)
{
try {
DocumentBuilderFactory documentBuilderFactory = DocumentBuilderFactory.newInstance();
DocumentBuilder documentBuilder = documentBuilderFactory.newDocumentBuilder();
Document document = documentBuilder.parse("D:\\Log.xml");
Element root = document.getDocumentElement();
Element newlog = document.createElement("log");
Element name = document.createElement("date");
name.appendChild(document.createTextNode(date));
Element name1 = document.createElement("type");
name1.appendChild(document.createTextNode(type));
Element name2 = document.createElement("message");
name2.appendChild(document.createTextNode(message));
newlog.appendChild(name);
newlog.appendChild(name1);
newlog.appendChild(name2);
root.appendChild(newlog);
System.out.println(root.getTextContent()+" "+document.getTextContent());
System.out.println("Dude working");
}
catch(Exception e)
{
System.out.println(e.toString());
}
}
You need a TransformerFactory
to save the changes. 您需要一个
TransformerFactory
来保存更改。
TransformerFactory transformerFactory = TransformerFactory.newInstance();
Transformer transformer = transformerFactory.newTransformer();
DOMSource source = new DOMSource(document);
StreamResult result = new StreamResult(new File("D:\\Log.xml"));
transformer.transform(source, result);
