我目前的代码是：
$dom = new DOMDocument();
$dom->loadXML($data);
$xpath = new DOMXpath($dom);
foreach ($dom->childNodes as $node) {
echo $node->nodeName . "\n";
}
哪个输出：
是否可能以某种方式（例如使用DOMXpath）直接获取（没有按名称循环childNodes）xml-stylesheet节点？
实施例
<?xml version="1.0" encoding="utf-8"?>
<?xml-stylesheet type="text/xsl" href="../../../ver20/util/onvif-wsdl-viewer.xsl"?>

childNodes中的排名并不总是第一位。
