我想使用创建文件。XMLJava

我的文件结构：XML

<?xml version="1.0" encoding="UTF-8"?>
<CONFIGURATION>
    <BROWSER>chrome</BROWSER>
    <BASE>http:fut</BASE>
    <ENVIRONMENT>abcd</ENVIRONMENT>
    <USER>john</USER>
    <PASSWORD>abcd123</PASSWORD>
    <ORGANIZATION>Tim</ORGANIZATION>
    <EMPLOYEE>
        <EMP_NAME>Anhorn, Irene</EMP_NAME>
        <ACT_DATE>20131201</ACT_DATE>
        <DATE_IN>20131201</DATE_IN>
        <CLOCK_IN>0800</CLOCK_IN>
        <DATE_OUT>20131201</DATE_OUT>
        <CLOCK_OUT>1600</CLOCK_OUT> 
    </EMPLOYEE>
    <EMPLOYEE>
        <EMP_NAME>Arlegui, Karen Jay</EMP_NAME>
        <ACT_DATE>20131201</ACT_DATE>
        <DATE_IN>20131201</DATE_IN>
        <CLOCK_IN>1600</CLOCK_IN>
        <DATE_OUT>20131202</DATE_OUT>
        <CLOCK_OUT>0000</CLOCK_OUT> 
    </EMPLOYEE>
</CONFIGURATION>

答案 1

您可以在 Java 中使用 JDOM 库。将标记定义为元素对象，使用文档类记录元素，并使用 SAXBuilder 构建 xml 文件。试试这个例子：

//Root Element
Element root=new Element("CONFIGURATION");
Document doc=new Document();
//Element 1
Element child1=new Element("BROWSER");
//Element 1 Content
child1.addContent("chrome");
//Element 2
Element child2=new Element("BASE");
//Element 2 Content
child2.addContent("http:fut");
//Element 3
Element child3=new Element("EMPLOYEE");
//Element 3 --> In this case this element has another element with Content
child3.addContent(new Element("EMP_NAME").addContent("Anhorn, Irene"));

//Add it in the root Element
root.addContent(child1);
root.addContent(child2);
root.addContent(child3);
//Define root element like root
doc.setRootElement(root);
//Create the XML
XMLOutputter outter=new XMLOutputter();
outter.setFormat(Format.getPrettyFormat());
outter.output(doc, new FileWriter(new File("myxml.xml")));

答案 2

public static void main(String[] args) {

try {

    DocumentBuilderFactory docFactory = DocumentBuilderFactory.newInstance();
    DocumentBuilder docBuilder = docFactory.newDocumentBuilder();
    Document doc = docBuilder.newDocument();
    Element rootElement = doc.createElement("CONFIGURATION");
    doc.appendChild(rootElement);
    Element browser = doc.createElement("BROWSER");
    browser.appendChild(doc.createTextNode("chrome"));
    rootElement.appendChild(browser);
    Element base = doc.createElement("BASE");
    base.appendChild(doc.createTextNode("http:fut"));
    rootElement.appendChild(base);
    Element employee = doc.createElement("EMPLOYEE");
    rootElement.appendChild(employee);
    Element empName = doc.createElement("EMP_NAME");
    empName.appendChild(doc.createTextNode("Anhorn, Irene"));
    employee.appendChild(empName);
    Element actDate = doc.createElement("ACT_DATE");
    actDate.appendChild(doc.createTextNode("20131201"));
    employee.appendChild(actDate);
    TransformerFactory transformerFactory = TransformerFactory.newInstance();
    Transformer transformer = transformerFactory.newTransformer();
    DOMSource source = new DOMSource(doc);
    StreamResult result = new StreamResult(new File("/Users/myXml/ScoreDetail.xml"));
    transformer.transform(source, result);
    System.out.println("File saved!");
  } catch (ParserConfigurationException pce) {
    pce.printStackTrace();
  } catch (TransformerException tfe) {
    tfe.printStackTrace();}}

XML 中的值是硬编码的。
