配置xml文件

<?xml version="1.0" encoding="UTF-8" ?>
<books>
  <book>
    <name>时间简史</name>
    <auth>霍金</auth>
    <price>69.9</price>
  </book>
  <book>
    <name><![CDATA[<<面纱>>]]></name>
    <auth>毛姆</auth>
    <price>12.5</price>
  </book>

</books>

实体类

public class Book {
  private String name;
  private String auth;
  private double price;


  public void setName(String name) {
    this.name = name;
  }

  public void setAuth(String auth) {
    this.auth = auth;
  }

  public void setPrice(int price) {
    this.price = price;
  }

  public String getName() {
    return name;
  }

  public String getAuth() {
    return auth;
  }

  public double getPrice() {
    return price;
  }

  public Book(String name, String auth, double price) {
    this.name = name;
    this.auth = auth;
    this.price = price;
  }

  public Book() {
  }

  @Override
  public String toString() {
    return "Book{" +
      "name='" + name + '\'' +
      ", auth='" + auth + '\'' +
      ", price=" + price +
      '}';
  }
}

SAXReader reader = new SAXReader();
//读取xml文件
Document doc = reader.read("books.xml");

//获取根标签
List<Element> books = rootElement.elements("book");
List<Book> books1 = new ArrayList<>();
//找到指定标签

//获取标签中的文本
String name = elementName.getText();
String auth = elementAuth.getText();
