11.PHP生成XML数据，android解析XML案例简介

PHP生成XML数据：

<?php

$dom = new DOMDocument("1.0");  //生成XML头部

header("Content-Type: text/plain");   //确定页面类型

$persons = $dom->createElement("persons");  //生成节点元素

$dom->appendChild($persons);      //添加为子节点，此子节点是头节点

$person = $dom->createElement("person");

$persons->appendChild($person);  //添加子节点

$id=$dom->createAttribute("id");        //生成属性节点

$person->appendChild($id);

$id_v=$dom->createTextNode("1");  //生成属性值

$id->appendChild($id_v);

$name=$dom->createElement("name");

$person->appendChild($name);

$name_v=$dom->createTextNode("cai"); 生成节点值

$name->appendChild($name_v);

$phone=$dom->createElement("phone");

$person->appendChild($phone);

$data=$dom->createTextNode("11111");

$phone->appendChild($data);

echo $dom->saveXML();   //输出XML

?>

结果：

  <?xml version="1.0"?>

-<persons>

-<person id="1">

 
<name>cai</name>

 
<phone>11111</phone>

  </person>

-<person id="2">

 
<name>tou</name>

 
<phone>22222</phone>

  </person>

  </persons>

android 解析XML数据：

public class parsexml {

URL uri = new URL(path);

HttpURLConnection conn=(HttpURLConnection) uri.openConnection();

conn.setConnectTimeout(5000); //连接过期时间5S

  conn.setRequestMethod("GET");  //使用get请求

  if(conn.getResponseCode()==200){  //成功状态200

  InputStream instream= conn.getInputStream();  //获取数据流

return pasexml(instream);

}

return null;

}

private static List<people> pasexml (InputStream instream) throws Exception {

List<people> peoples=new ArrayList<people>();

people p=null;

XmlPullParser parser=Xml.newPullParser();  //生成解析器对象

parser.setInput(instream,"UTF-8"); 

  int event=parser.getEventType();  //获取解析事件类型，即解析到那个节点

while(event!=XmlPullParser.END_DOCUMENT){

switch (event) {

case XmlPullParser.START_TAG:

if("person".equals(parser.getName())){

int id=new Integer(parser.getAttributeValue(0)); //获取属性值

p=new people();

p.setId(id);

}else if("name".equals(parser.getName())){

p.setName(parser.nextText());   //获取节点值

}else if("phone".equals(parser.getName())){

p.setPhone(parser.nextText());

}

break;

case XmlPullParser.END_TAG:

if("person".equals(parser.getName())){

peoples.add(p);

p=null;

}

break;

default:

break;

}

event=parser.next();

}

return peoples;

}
