如何在PHP中创建DOMNode？ [英] How to create a DOMNode in PHP?

问题描述

课程 DOMNode 不提供构造器，也没有提供 static 方法，如 createInstance（）。那么，如何创建一个 DOMNode 实例？

The class DOMNode doesn't provide a contructor and also no static methods like createInstance(). So, how to create an DOMNode instance?

推荐答案

创建一个 DOM文档。它从DOMNode扩展，具有构造函数，并且表示文档的根节点。作为DOMNode，DOMDocument具有添加子项的方法。例如，DOMDocument有一个方法 CreateElement ，它返回一个DOMElement，其中也从DOMNode继承。总而言之，DOMNode似乎只是基类，不能直接使用。

Create a DOMDocument. It extends from DOMNode, has a constructor, and represents the rootnode of a document. Being a DOMNode, DOMDocument has methods for adding children. For instance, DOMDocument has a method CreateElement, which returns a DOMElement, which also inherits from DOMNode. All in all, it seems that DOMNode is just the base class and shouldn't be used directly.
