Java——DOM4J生成XML

DOM4J生成XML

創建Document 對象，代表整個 XML 文檔

//創建Document 對象，代表整個 xml文檔
Document document = DocumentHelper.createDocument();

創建根節點

//創建根節點
Element school = document.addElement("school");

創建子節點以及子節點的屬性和屬性值

//創建子節點
Element student = school.addElement("student"); 
//子節點的屬性
student.addAttribute("id", "1");

創建 student下的子節點以及添加內容

//創建 student下的子節點
Element name = student.addElement("name");
//添加內容
name.setText("張三");

 自動格式話 XML 文件

//自動格式化xml 文件
OutputFormat format = OutputFormat.createPrettyPrint();

創建 XML 文件

//創建 XML 文件
File file =new File("DOM4JXML.xml");

XMLWriter writer = new XMLWriter(new FileOutputStream(file),format);
//特殊字符，是否轉義，默認為true
writer.setEscapeText(false);
writer.write(document);
writer.close();

運行結果：

<?xml version="1.0" encoding="UTF-8"?>

<school>
  <student id="1">
    <name>張三</name>
  </student>
</scho
