使用 php 在 xpath 之后从 simplexml_load_file 中获取数组中的 @attributes
get @attributes out of array from simplexml_load_file after xpath with php
我有一个 xml，在使用 simplexml_load_file.
加载 xml 后，我可以使用 xpath 获取包含我需要的数据的数组
我这样试过：Access @attributes data in SimpleXMLElement in PHP
用我的 XML 阵列我仍然无法访问节点，有人可以检查我的代码：谢谢
$result2 = $xml->xpath("//file[@Catid='151']");
这是给这个数组：

如何访问 'path' 等值？我有问题
[0] => 简单XML元素对象那么节点的名称是什么？
echo (string)$result2->0[0]->attributes()->path;
没用.....
谢谢
尽管使用 XML 进行检查会更容易，但您可能会发现正确的表示法是...
echo (string)$result2[0]->attributes()->path;
这假定您需要 XPath 找到的第一个项目。
您可能还会发现
echo (string)$result2[0]['path'];
有效（但并非总是如此）。
