PHP 中的 SimpleXML；将节点替换为文本节点
给定这个 XML/XHTML 片段：
<h1>
<zuq:data name="siteHeader" />
</h1>
<h2>
<zuq:data name="pageHeaderName" />
<span>—</span>
<zuq:data name="pageHeaderTitle" />
</h2>
我使用 SimpleXML 的 XPath 方法来四舍五入 zuq 命名空间中的所有顶级节点。由于 xpath() 方法的数组元素是对 SimpleXML 对象树节点的伪引用，因此我认为操作会很容易。但是，我无法弄清楚如何用文本节点替换给定的元素节点。例如，我如何将 My Site Header。
我考虑过简单地定位父节点并修改其内容，以便可以与第一个块 (
有没有一种简单的方法可以通过 PHP 中的 SimpleXML 将给定元素节点替换为文本节点？
Given this XML/XHTML snippet:
<h1>
<zuq:data name="siteHeader" />
</h1>
<h2>
<zuq:data name="pageHeaderName" />
<span>—</span>
<zuq:data name="pageHeaderTitle" />
</h2>
I've used SimpleXML's XPath method to round up all top-level nodes in the zuq namespace. Since the array elements of the xpath() method are pseudo references to the SimpleXML object tree nodes, I figured manipulation would be easy. However, I cannot figure out how to replace a given element node with a text node. How could I, for example, replace <zuq:data name="siteHeader" /> with the text My Site Header.
I've considered simply targeting the parent node and modifying it's contents as could work with the first block (<h1>), but I don't see that working given the case of my second block (<h2>).
Is there an easy way to replace a given element node with a text node via SimpleXML in PHP?

据我所知，simplexml 不具备删除或替换节点的功能。它更适合阅读、创建和非结构相关的编辑。您必须使用 DOM XML 对象来完全替换节点。它有点像 simplexml 的更复杂版本。在这里阅读：

as far as i know, simplexml doesn't have the capability to remove or replace nodes. it's more for reading, creating, and non-structure related edits. you will have to use a DOM XML object to fully replace nodes. it's sort of like a more complex version of simplexml. read about it here:

快速查看文档我也找不到简单的方法。我会尝试迭代原始 xml 文档并将每个元素复制到新的 xml 文档，并根据需要修改它们。
Quickly looking at the documentation I was not able to find a simple way either. I would try to just iterate over the original xml doc and copy each element to a new xml doc, modifying them as necessary.
