DOM4J解析XML檔案

public class DOM4JTest1 {

        //1.建立解析的類
        SAXReader reader = new SAXReader();

        //2.開始解析 形成文檔樹
        Document document = reader.read("D:/mycode/XML/teacher/students2.xml");

        //3.擷取根節點
        Element rootElement = document.getRootElement();
        //4.擷取位元組點

        List<Element> students = rootElement.elements("student");

        for (Element student : students) {
            //5.擷取屬性
            //擷取指定的屬性
            Attribute attribute = student.attribute("id");
            System.out.println(attribute.getName()+"<===>"+attribute.getValue());

                System.out.println(attribute.getName()+"<===>"+attribute.getValue());
            }*/
            //6.擷取孫子元素

            List<Element> childStudents = student.elements();
            //7.擷取孫子元素的内容

            childStudents.forEach((x)->{
                System.out.println( x.getName()+"<======>"+x.getText());
            });

           /* for (Element x : childStudents) {
                System.out.println( x.getName()+"<======>"+x.getText());
            }*/
            System.out.println();
        }
