我正在尝试从 Java 创建一个动态生成的 XML 文件。这是我尝试使用的代码:
try{
BufferedReader bf = new BufferedReader(new InputStreamReader(System.in));
System.out.println("how many elements: ");
String str = bf.readLine();
int no = Integer.parseInt(str);
System.out.println("enetr root: ");
String root = bf.readLine();
DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
DocumentBuilder db = dbf.newDocumentBuilder();
Document d1 = db.newDocument();
Element e1 = d1.createElement(root);
d1.appendChild(e1);
for (int i = 0; i < no; i++) {
System.out.println("enter element: ");
String element = bf.readLine();
System.out.println("enter data: ");
String data = bf.readLine();
Element em = d1.createElement(element);
em.appendChild(d1.createTextNode(data));
e1.appendChild(em);
}
TransformerFactory tf = TransformerFactory.newInstance();
Transformer transformer = tf.newTransformer();
DOMSource source = new DOMSource(d1);
File file = new File("src\\xml\\copy.xml");
System.out.println(file);
if(!file.exists()){
file.createNewFile();
}
OutputStream outputStream = new FileOutputStream(file);
StreamResult result = new StreamResult(outputStream);
transformer.transform(source, result);
outputStream.close();
}catch (Exception e) {
// TODO: handle exception
e.printStackTrace();
System.out.println("file not created");
}
此代码运行良好。但是现在我有一个这样的字符串:
String xmlRecords = "<data><terminal_id>1000099999</terminal_id><merchant_id>10004444</merchant_id><merchant_info>Mc Donald's - Abdoun</merchant_info></data>";
我想从这个 xmlRecords
变量创建一个 .xml
文件。我该怎么做?
最佳答案
您可以像这样将 XML 字符串解析为 Document
:
String xmlRecords = "<data><terminal_id>1000099999</terminal_id><merchant_id>10004444</merchant_id><merchant_info>Mc Donald's - Abdoun</merchant_info></data>";
DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
DocumentBuilder builder = factory.newDocumentBuilder();
Document d1 = builder.parse(new InputSource(new StringReader(xmlRecords)));
您可以保留问题中提到的文件编写部分,只需将 Document
实例的创建替换为上述代码即可。
