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. Though the API is object-oriented, there
are many functions which can be called in a non-object-oriented
way by passing the object to operate on as the first argument.
These functions are mainly to retain compatibility to older
versions of the extension, and should not be used when creating
new scripts.
This API differs from the official DOM API in two ways.
First, all class attributes are implemented as functions
with the same name. Secondly, the function names follow
the PHP naming convention. This means that a DOM function
lastChild() will be written as last_child().
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.
