采用Pull解析器解析和生成XML内容.

Xml对象：

 

/**
      * 获取数据
      * @param xml
      * @return
      * @throws Exception
      */
     public static List<Person> getPersons(InputStream xml) throws Exception
     {
         List<Person> persons = null;
         Person person = null;
 
         XmlPullParser pullParser = Xml.newPullParser();
         pullParser.setInput(xml, "UTF-8");//为Pull解析器设置要解析的XML数据
         int event = pullParser.getEventType();
 
         while(event != XmlPullParser.END_DOCUMENT)
         {
             switch (event) 
             {
             case XmlPullParser.START_DOCUMENT:
                 persons = new ArrayList<Person>(); //<?xml version = "1.0" encoding = "UTF-8">
                 break;
                 
             case XmlPullParser.START_TAG:
 
                 if("person".equals(pullParser.getName())){
                     int id = new Integer(pullParser.getAttributeValue(0));
                     person = new Person();
                     person.setId(id);
                 }
                 if(person != null)
                 {
                     if("name".equals(pullParser.getName()))
                     {
                         String name = pullParser.nextText();
                         person.setName(name);
                     }
                     if("age".equals(pullParser.getName()))
                     {
                         int age = new Integer(pullParser.nextText());
                         person.setAge(age);
                     }
                 }
                 
                 break;
                 
             case XmlPullParser.END_TAG:
                 if("person".equals(pullParser.getName())){
                     persons.add(person);
                     person = null;
                 }
                 break;
             }//switch
             event = pullParser.next();
         }
         return persons;
     }

用Pull解析器生成数据

/**
      * 保存数据
      * @param persons 数据
      * @param out 输出方向
      * @throws Exception
      */
     public static void save(List<Person> persons, OutputStream out) throws Exception{
 
         XmlSerializer serializer = Xml.newSerializer();
         serializer.setOutput(out, "UTF-8");
         serializer.startDocument("UTF-8", true);
         serializer.startTag(null, "persons");
 
         for(Person person : persons)
         {
             serializer.startTag(null, "person");
             serializer.attribute(null, "id", person.getId().toString());
             
             serializer.startTag(null, "name");
             serializer.text(person.getName());
             serializer.endTag(null, "name");
             
             serializer.startTag(null, "age");
             serializer.text(person.getAge().toString());
             serializer.endTag(null, "age");
             
             serializer.endTag(null, "person");
         }
 
         serializer.endTag(null, "persons");
         serializer.endDocument();
         out.flush();
         out.close();
     }
 }

利用类加载器获取项目里的XML文件

public void testPersons() throws Exception{
 
         InputStream xml = this.getClass().getClassLoader().getResourceAsStream("person.xml");
         List<Person> persons = PersonService.getPersons(xml);
         for(Person person : persons){
             Log.i(TAG, person.toString());
         }
     }
