What is the DOM?

The DOM is a W3C (World Wide Web Consortium) standard.

The DOM defines a standard for accessing documents like XML and HTML:

"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 DOM is separated into 3 different parts / levels:

• Core DOM - standard model for any structured document
• XML DOM - standard model for XML documents
• HTML DOM - standard model for HTML documents

The DOM defines the objects and properties of all document elements, and the methods (interface) to access them.

What is the HTML DOM?

The HTML DOM defines the objects and properties of all HTML elements, and the methods (interface) to access them.

If you want to study the HTML DOM, find the HTML DOM tutorial on our homepage.

What is the XML DOM?

The XML DOM is:

• A standard object model for XML
• A standard programming interface for XML
• Platform- and language-independent
• A W3C standard

The XML DOM defines the objects and properties of all XML elements, and the methods (interface) to access them.

In other words:

The XML DOM is a standard for how to get, change, add, or delete XML elements.
