解析如下xml文件

<?xml version="1.0" encoding="UTF-8"?>
<persons>
     <person id="1">
            <name>GIS</name>
            <age>23</age>
      </person>
      <person id="2">
            <name>ArcGIS</name>
            <age>24</age>
      </person>
</persons>

创建一个person对象

public class Person {
    private Integer id;
    private String name;
    private Short age;
    
    public Person(){}
    
    public Person(Integer id, String name, Short age) {
        super();
        this.id = id;
        this.name = name;
        this.age = age;
    }
    @Override
    public String toString() {
        return "Person [id=" + id + ", name=" + name + ", age=" + age + "]";
    }
    public Integer getId() {
        return id;
    }
    public void setId(Integer id) {
        this.id = id;
    }
    public String getName() {
        return name;
    }
    public void setName(String name) {
        this.name = name;
    }
    public Short getAge() {
        return age;
    }
    public void setAge(Short age) {
        this.age = age;
    }

}

1.dom解析

import java.util.List;

import javax.xml.parsers.DocumentBuilderFactory;

import org.w3c.dom.Document;

public class DOMService {
    public List<Person> getHongXml(InputStream inStream) throws Throwable {
        List<Person> persons = new ArrayList<Person>();
        DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
        DocumentBuilder builder = factory.newDocumentBuilder();
        Document document = builder.parse(inStream);//结束后以文档树的方式存放在内存
        Element root = document.getDocumentElement();
        NodeList persoNodes = root.getElementsByTagName("person");
        for (int i = 0; i < persoNodes.getLength(); i++) {
            Person person = new Person();
            Element personElement = (Element)persoNodes.item(i);
            person.setId(new Integer(personElement.getAttribute("id")));
            NodeList personChilds = personElement.getChildNodes();
            for (int j = 0; j < personChilds.getLength(); j++) {
                if (personChilds.item(j).getNodeType() == Node.ELEMENT_NODE) {//判断当前节点是否是元素类型节点
                    Element childElement = (Element)personChilds.item(j);
                    if ("name".equals(childElement.getNodeName())) {
                        person.setName(childElement.getFirstChild().getNodeva lue());
                    }else if ("age".equals(childElement.getNodeName())) {
                        person.setAge(new Short(childElement.getFirstChild().getNodeva lue()));
                    }
                }
            }
            persons.add(person);
        }
        return persons;
    }

import java.util.ArrayList;
import java.util.List;
import org.xmlpull.v1.XmlPullParser;
import org.xmlpull.v1.XmlSerializer;

import android.util.Xml;
import yu.entity.Person;
