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：

import java.net.HttpURLConnection;
import java.net.URL;
import java.util.ArrayList;
import java.util.List;
import org.xmlpull.v1.XmlPullParser;
import android.util.Xml;

public class parsexml {

public static List<people> getlastnews() throws Exception {
String path = "http://192.168.0.117/testxml/xml.php"; //远程XML数据
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;
}
