java - xml解析器数据到文本文件

Question

我正在浏览 xml 解析器的代码，我找到了这段代码，但我想将结果数据保存到文本文件中。

public class ReadXMLFile 
{

public static void main(String argv[]) 
{

  try {

    File fXmlFile = new File("test.xml");
    DocumentBuilderFactory dbFactory = DocumentBuilderFactory.newInstance();
    DocumentBuilder dBuilder = dbFactory.newDocumentBuilder();
    Document doc = dBuilder.parse(fXmlFile);
    doc.getDocumentElement().normalize();

    System.out.println("Root element :" + doc.getDocumentElement().getNodeName());
    NodeList nList = doc.getElementsByTagName("test");
    System.out.println("-----------------------");

    for (int temp = 0; temp < nList.getLength(); temp++) {

       Node nNode = nList.item(temp);
       if (nNode.getNodeType() == Node.ELEMENT_NODE) {

          Element eElement = (Element) nNode;

          System.out.println("ID : " + getTagValue("id", eElement));
          System.out.println("Name : " + getTagValue("Name", eElement));
          System.out.println("AGE: " + getTagValue("age", eElement));

       }
    }
  } 
  catch (Exception e) 
  {
    e.printStackTrace();
  }
 }

 private static String getTagValue(String sTag, Element eElement) 
{
NodeList nlList = eElement.getElementsByTagName(sTag).item(0).getChildNodes();

    Node nValue = (Node) nlList.item(0);

return nValue.getNodeValue();
}

}

如何将输出保存到文本文件？

请就此向我提出建议.......

创建一个 Writer 以写入文件并将 System.out.println() 替换为 Writer.write()。

BufferedWriter writer = new BufferedWriter(new FileWriter(file));
writer.write(s);
writer.newLine();
