请教高手,PHP读取XML文件.

[yangchang]

我现在有个XML文件,想读取其中一个节点的数据,但是这个节点下面还有一个子节点,就不知道怎么读取了,请高手帮忙,最好能给出代码!

[CunningBoy]

simplexml_load_file载入XML文件
SimpleXMLElement::children访问字节点
SimpleXMLElement::attributes访问节点属性

具体例子参看PHP官方手册：http://www.php.net/manual/en/book.simplexml.php

你看哈php中的dom

下面是从上面弄下来的一段代码:

<?php
$xml =<<<EOT
<?xml version="1.0"?>
<config>
  <section id="section1">
   <param name="param1">value1</param>
   <param name="param2">value2</param>
  </section>
  <section id="section2">
   <param name="param3">value3</param>
  </section>
</config>
EOT;

$dom = new DomDocument;
$dom->preserveWhiteSpace = FALSE;
$dom->loadXML($xml);
$params = $dom->getElementsByTagName('param');

foreach ($params as $param) {
       echo $param -> getAttribute('name').'<br>';
}
?>

Expected result:
--------------
param1
param2
param3

Domlist DOMDocument::getElementsByTagName()

[程序猿之殇]

<?xml version="1.0" encoding="gb2312"?>   
<document>    
<dup id="1">    
    <link>link2</link>    
    <title>title1</title>    
</dup>    
<dup id="2">    
    <link>testlink2 </link>    
    <title>testtitle2 </title>    
</dup>    
</document>  


$xmldata=simplexml_load_file("t1111.xml");    
$dup = $xmldata->xpath("/document/dup[@id='1']");   
var_dump($dup);
