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;

}

?>
