class xpathExtension{ 
public static function getNodes($domDoc, $xpathString) { 
$xp = new DOMXPath($domDoc); 
$xp->registerNamespace('x', 'http://www.w3.org/1999/xhtml'); 
$xp->registerNamespace('xhtml', 'http://www.w3.org/1999/xhtml'); 
$xp->registerNamespace('i18n', 'http://apache.org/cocoon/i18n/2.1'); 
$ret = array(); 
$nodes = $xp->query($xpathString); 
foreach ($nodes as $node) { 
array_push($ret, $node); 
} 
return $ret; 
} 
} 
$domDoc = new DOMDocument(); 
$domDoc->load("x1.xml"); 
$xpathString = "//xml/products/product/description"; 
$domNodeList = xpathExtension::getNodes($domDoc, $xpathString); 
//echo count($domNodeList); 
foreach($domNodeList as $domNode){ 
echo $domNode->nodeValue; 
} 
?> 

代码如下:

 
<?xml version="1.0" encoding="utf-8" ?> 
<xml> 
<products> 
<product> 
<description> 
abcd 
</description> 
</product> 
</products> 
</xml>
