Pull解析-解析xml文件

 首先需要导入jar包：kxml2-2.2.2.jar

例程：

main：

/**
 * pull解析
 * 
 * @author my
 *
 */
public class DemoParserStudent {
    public static void main(String[] args) {
        try {
            // 1.创建解析器工厂对象
            XmlPullParserFactory factory = XmlPullParserFactory.newInstance();
            // 2.创建解析器对象
            XmlPullParser parser = factory.newPullParser();
            // 3.指定数据源
            parser.setInput(new FileReader("Students.xml"));
            // 4.获得响应码
            int code = parser.getEventType();
            Student s = null;
            List<Student> list = null;
            while (code != parser.END_DOCUMENT) {
                String name = parser.getName();// 获得标签名称
                switch (code) {
                case XmlPullParser.START_TAG:
                    if ("Students".equals(name)) {
                        list = new ArrayList<Student>();
                    } else if ("Student".equals(name)) {
                        s = new Student();

                    } else if ("name".equals(name)) {
                        s.setName(parser.nextText());
                    } else if ("age".equals(name)) {
                        s.setAge(new Integer(parser.nextText()));
                    } else if ("sex".equals(name)) {
                        s.setSex(parser.nextText());
                    }
                    break;
                case XmlPullParser.END_TAG:
                    if ("Student".equals(name)) {
                        list.add(s);
                    }
                    break;
                }
                code = parser.next();
            }
            for (Student student : list) {
                System.out.println(student);
            }
        } catch (XmlPullParserException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        } catch (FileNotFoundException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        } catch (IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
    }
}

Student:

package com.qf.PullParser;

public class Student {
    String no;
    String name;
    int age;
    String sex;

    public String getNo() {
        return no;
    }

    public void setNo(String no) {
        this.no = no;
    }

    public String getName() {
        return name;
    }

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

    public int getAge() {
        return age;
    }

    public void setAge(int age) {
        this.age = age;
    }

    public String getSex() {
        return sex;
    }

    public void setSex(String sex) {
        this.sex = sex;
    }

    @Override
    public String toString() {
        return "Student [no = " + no + " name=" + name + ", age=" + age + ", sex=" + sex + "]";
    }

}
