PHP读取XML 值 - PHP读取XML 内容 (一)

用Php读取XML最简单的情况:
XML文件(cy.xml)如下:
<?xml version="1.0" encoding="gb2312"?>
<xml>
<list>1</list>
<list>2</list>
<list>3</list>
</xml>
Php文件(cy.php)如下:
<?php
$xml = new DOMDocument();
$xml->load('cy.xml');
foreach($xml->getElementsByTagName('list') as $list)
{
$value = $list->firstChild->nodeValue;
echo $value."<br />";
}
?>
cy.php的运行结果:
1
2
3
=============
用Php读取XML稍微复杂一点的情况:
cy.xml如下:
<?xml version="1.0" encoding="gb2312"?>
<xml>
<main>
<list>1</list>
<list>2</list>
<list>3</list>
</main>
</xml>
cy.php如下(和第一种情况没有任何变化):
<?php
$xml = new DOMDocument();
$xml->load('cy.xml');
foreach($xml->getElementsByTagName('list') as $list)
{
$value = $list->firstChild->nodeValue;
echo $value."<br />";
}
?>
cy.php的运行结果和第一次也相同:
1
2
