XXIV. DOM Functions

Introduction

The DOM extension is the replacement for the DOM XML extension from PHP 4. The extension still contains many old functions, but they should no longer be used. In particular, functions that are not object-oriented should be avoided.

The extension allows you to operate on an XML document with the DOM API.

Predefined Constants

The constants below are defined by this extension, and will only be available when the extension has either been compiled into PHP or dynamically loaded at runtime.

Classes

The API of the module follows the DOM Level 2 standard as closely as possible. Consequently, the API is fully object-oriented. It is a good idea to have the DOM standard available when using this module.

This module defines a number of classes, which are listed - including their method - in the following tables. Classes with an equivalent in the DOM standard are named DOMxxx.
