What is DOM and XML?

What is W3C DOM?
“The W3C Document Object Model (DOM) is a platform and language-neutral interface that allows programs and scripts to dynamically access and update the content, structure, and style of a document.” The W3C DOM standard is separated into 3 different parts: Core DOM – standard model for all document types.

Why is DOM used?

How DOM is created?
A DOM tree starts from the topmost element which is html element and branches out as per the occurrence and nesting of HTML elements in the document. Whenever an HTML element is found, it creates a DOM node (Node) object from its respective class (constructor function).

What are the disadvantages of Dom?
Disadvantages of DOM

- Its operational speed is slower compared to SAX due to larger usage of memory.

Instead of specifying how objects may be represented in XML, the DOM specifies how XML and HTML documents are represented as objects, so that they may be used in object oriented programs. The Document Object Model is not a set of data structures; it is an object model that specifies interfaces.
