php获取xml中的数据,php 生成xml

PHP读取XML数据

编码问题,function

characterData改成如下

function

characterData($parser_instance,

$xml_data)

{

global

$name,$position;

$xml_data=iconv("utf-8","gb2312",$xml_data);//转换成gb2312

if($position)

echo

$xml_data."br";

if($name)

echo

$xml_data."br";

}

显示的那个页面也要有charset=gb2312

如何通过PHP生成和获取XML格式数据

1自己拼，XML编码

?php

header('Content-type:text/xml');

echo "?xml version='1.0' encoding='utf-8'";

echo "book";

echo "PHP";

echo "namePHP程序开发范例宝典/name";

echo "price 单位='元/本'89.00/price";

echo "date2007-09-01/date";

echo "/PHP";

echo "/book";

?

拼接的效果

2从数据库中查询再拼XML编码

?php

$dsn="mysql:host=localhost;dbname=test";

try {

$pdo = new PDO($dsn,'root','passwowd'); //初始化一个PDO对象，就是创建了数据库连接对象$pdo

$query="select * from book";   //定义SQL语句

$pdo-query('set names utf8');

$result=$pdo-prepare($query); //准备查询语句

$result-execute();       //执行查询语句，并返回结果集

$arr='';

while($res=$result-fetch()){

$arr.='PHPid'.$res[0].'/idname'.$res[1].'/namedate'.$res[2].'/date'.'price'.$res[3].'/price/PHP';

}

echo "?xml version='1.0' encoding='utf-8'?book".$arr.'/book';

} catch (PDOException $e) {

die ("Error!: ".$e-getMessage()."br");

}

?

拼接的效果

3使用ajax获取，DOM解析

!DOCTYPE html

html lang="en"

head

meta charset="UTF-8"

titlexml/title

/head

body

script

function check(){

var xhr=new XMLHttpRequest();

xhr.open('GET','xml.php');

xhr.onreadystatechange=function(){

if(xhr.readyState==4 xhr.status==200){

console.log(xhr.responseText);

//初始化 DOM解析对象

var domParser = new DOMParser();

//字符串解码为对象

var xmlDoc = domParser.parseFromString(xhr.responseText,'text/xml');

//按标签名获取元素 返回数组

var elements = xmlDoc.getElementsByTagName('PHP');

//拼接html格式字符串

var str ='trthid/ththname/ththdate/ththprice/th/tr';

for (var i=0;ielements.length;i++){

var id=elements[i].getElementsByTagName('id')[0].firstChild.nodeValue;

var name=elements[i].getElementsByTagName('name')[0].firstChild.nodeValue;

var date=elements[i].getElementsByTagName('date')[0].firstChild.nodeValue;

var price=elements[i].getElementsByTagName('price')[0].firstChild.nodeValue;

str+= 'trtd'+id+'/tdtd'+name+'/tdtd'+date+'/tdtd'+price+'/td/tr';

}

document.getElementById('table2').innerHTML=str;

}

};

xhr.send(null);

}

/script

button onclick="check();"点我/button

table id="table2" border="2" cellspacing="0"

/table

/body

/html

补充：

使用JSON

1数据库查询，自己拼 JSON 编码

?php

$dsn="mysql:host=localhost;dbname=test";

try {

$pdo = new PDO($dsn,'root','password'); //初始化一个PDO对象，就是创建了数据库连接对象$pdo

$query="select * from book";   //定义SQL语句

$pdo-query('set names utf8');

$result=$pdo-prepare($query); //准备查询语句

$result-execute();       //执行查询语句，并返回结果集

$a=$arr='';

while($res=$result-fetch()){

$arr.='{"id":'.'"'.$res[0].'",'.'"name":'.'"'.$res[1].'",'.'"time":'.'"'.$res[2].'",'.'"jia":'.'"'.$res[3].'",'.'"zhe":'.'"'.$res[4].'",'.'"chu":'.'"'.$res[5].'"},';

}

echo $a="[".substr($arr,0,strlen($arr)-1)."]";

} catch (PDOException $e) {

die ("Error!: ".$e-getMessage()."br");

}

?

2数据库查询，函数 JSON 编码

?php

$dsn="mysql:host=localhost;dbname=test";

try {

$pdo = new PDO($dsn,'root','password'); //初始化一个PDO对象，就是创建了数据库连接对象$pdo

$query="select * from book";   //定义SQL语句

$pdo-query('set names utf8');

$result=$pdo-prepare($query); //准备查询语句

$result-execute();       //执行查询语句，并返回结果集

$res=$result-fetchAll();

//JSON 编码

echo json_encode($res);

} catch (PDOException $e) {

die ("Error!: ".$e-getMessage()."br/");

}

?

效果

3ajax获取，JSON解析

!DOCTYPE html

html lang="en"

head

meta charset="UTF-8"

titleJSON/title

/head

body

script

function check() {

var XHR = new XMLHttpRequest();

XHR.open('GET','JSON.php');

XHR.onreadystatechange = function (){

if(XHR.readyState == 4 XHR.status ==200){

var books =JSON .parse(XHR.responseText);

var books2='trthid/ththbookname/ththtime/ththprice/ththmarker/ththpublisher/th/tr'

for (var i=0;ibooks.length;i++){

books2+= 'trtd'+(books[i ].id)+'/tdtd'+(books[i ].name)+'/tdtd'+(books[i ].time)+'/tdtd'+(books[i ].jia)+'/tdtd'+(books[i ].zhe)+'/tdtd'+(books[i ].chu)+'/td/tr';

}

document.getElementById('table2').innerHTML=books2;

}

};

XHR.send(null);

}

/script

input type="button" value="点我" onclick="check();"

table id="table2" border="2" cellspacing="0"/table

/body

/html

PHP 读取 XML中指定内容

$xml = "returnsmsreturnstatusSuccess/returnstatusmessageok/messageremainpoint-43779/remainpoint taskid496370/taskid/returnsms";

$ob = simplexml_load_string($xml);

echo "returnstatus is:".$ob-returnstatus;

echo "br /";

echo "message is:".$ob-message;

echo "br /";

echo "remainpoint is:".$ob-remainpoint;

echo "br /";

echo "taskid is:".$ob-taskid;

//var_dump($ob);

//用simplexml_load_string()函数来解析

php 获取 XML 数值

$strxml = file_get_contents(url);

$xml = simplexml_load_string($strxml);

下面就会了吧！！

PHP 获取XML数据

给个小例子：

1.直接是xml字符串

?php

$string = XML

?xml version='1.0'? 

document

 titleForty What?/title

 fromJoe/from

 toJane/to

 body

  I know that's the answer -- but what's the question?

 /body

/document

XML;

$xml = simplexml_load_string($string);

print_r($xml);

? 

2. xml文件的

?php

if (file_exists('test.xml')) {

    $xml = simplexml_load_file('test.xml');

 

    print_r($xml);

} else {

    exit('Failed to open test.xml.');

}

php如何获取xml数据包

//提取XML数据源

$xmlUrl= '';

echo $xmlUrl;

$curl= curl_init();

curl_setopt($curl, CURLOPT_URL, $xmlUrl);

curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);

curl_setopt($curl, CURLOPT_CONNECTTIMEOUT, 10);

curl_setopt($curl, CURLOPT_HEADER, 0);

$xmlData= curl_exec($curl);

curl_close($curl);

//判断XML编码

if(preg_match("/encoding\=[\'\"](.*?)[\'\"]/i", $xmlData, $encoding)){

$encoding = $encoding[1];

}else{

$encoding = mb_detect_encoding($xmlData, array('ASCII', 'GBK', 'GB2312', 'UTF-8', 'iso-8859-1'));

}

echo $encoding;

//转换XML编码

if($encoding){

$xmlData = preg_replace('/encoding\=[\'\"](.*?)[\'\"]/i', 'encoding="utf-8"', $xmlData);

switch(strtolower($encoding)){

case 'utf-8': break;

case 'iso-8859-1':

$xmlData = utf8_encode($xmlData);

break;

default:

$xmlData = iconv($encoding, 'UTF-8//IGNORE', $xmlData);

break;

}

}

$xmlData= simplexml_load_string($xmlData);

print_r($xmlData);
