What is the DOM?
The DOM is a W3C (World Wide Web Consortium) standard.
The DOM defines a standard for accessing documents like HTML and XML:
"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 XML DOM?
The XML DOM defines the objects and properties of all XML elements,
and the methods (interface) to access them.
