pull读取xml-android

pull读取xml--android

pull解析xml文件,和sax和dom一样 都可以脱离android单独使用,pull和sax的原理一样,不一样的地方是pull读取xml文件后调用方法返回的是数字,
?? 读取到xml的声明返回数字0 START_DOCUMENT;
?? 读取到xml的结束返回数字1 END_DOCUMENT ;
?? 读取到xml的开始标签返回数字2 START_TAG
?? 读取到xml的结束标签返回数字3 END_TAG
?? 读取到xml的文本返回数字4 TEXT

?? pull是开源的项目 源码下载地址http://www.xmlpull.org/
? service中的代码

??serializer.startTag(null, "persons");
??for(Person person : persons){
???serializer.startTag(null, "person");???
???serializer.attribute(null, "id", String.valueOf(person.getId()));
???
???serializer.startTag(null, "name");
???serializer.text(person.getName());
???serializer.endTag(null, "name");
???
???serializer.startTag(null, "age");
???serializer.text(String.valueOf(person.getAge()));
???serializer.endTag(null, "age");?
???
???serializer.endTag(null, "person");
??}
??serializer.endTag(null, "persons");
??serializer.endDocument();
??writer.flush();
??writer.close();??
?}

写入xml文件测试

StringWriter writer = new StringWriter();
??List<Person> persons = new ArrayList<Person>();
??persons.add(new Person(12, "李明", new Short((short)36)));
??persons.add(new Person(78, "老张", new Short((short)26)));
??persons.add(new Person(90, "老毕", new Short((short)16)));
??PullPersonService.writeXml(persons, writer);
??Log.i(TAG, writer.toString());
