java - 如何创建一个像这样的简单 xml 文档

Question

我想创建一个如下所示的 xml 文档，但我不知道如何:

<bo type="Employee" id="0000012f41bce2a865f8616b0010007c0008008b">
  <username>marv</username>
</bo>

这就是我到目前为止所拥有的，我真的只是对如何添加 username 元素感到困惑:

Element bo = testDoc.createElement("bo");
        bo.setAttribute("type", "Employee");
        bo.setAttribute("id", emp.getId());

Answer 1

Element bo = testDoc.createElement("bo");
bo.setAttribute("type", "Employee");
bo.setAttribute("id", emp.getId());
//create a username element
Element username = testDoc.createElement("username");
//add a text value to the username element
username.appendChild(testDoc.createTextNode("marv"));
//add the username element as child of bo element
bo.appendChild(username);
