使用PHP的SimpleXML访问元素的父级? [英] Access an element's parent with PHP's SimpleXML?

问题描述

我正在遍历一组SimpleXML对象，但是我不知道如何访问每个对象的父节点.这就是我想要的:

I'm iterating through a set of SimpleXML objects, and I can't figure out how to access each object's parent node. Here's what I want:

$divs = simplexml->xpath("//div");
foreach ($divs as $div)
{
   $parent_div = $div->get_parent_node(); // Sadly, there's no such function.
}

似乎必须有一种相当简单的方法来完成此操作.

Seems like there must be a fairly easy way to do this.

推荐答案

您可以运行一个简单的XPath查询来获取它:

You could run a simple XPath query to get it:

$parent_div = $div->xpath("parent::*");

由于这是Simplexml，并且只有元素和属性节点，而父节点只能是元素，而不能是属性，因此可以使用缩写语法:

And as this is Simplexml and it only has element and attribute nodes and a parent node can only be an element and never an attribute, the abbreviated syntax can be used:

$parent_div = $div->xpath("..");
