SUMMARY

The Document Object Model (DOM) is a language-independent API for accessing and manipulating HTML and XML documents. DOM Level 1 deals with representing HTML and XML documents as a hierarchy of nodes that can be manipulated to change the appearance and structure of the underlying documents using JavaScript.

The DOM is made up of a series of node types, as described here:

• The base node type is Node, which is an abstract representation of an individual part of a document; all other types inherit from Node.
• The Document type represents an entire document and is the root node of a hierarchy. In JavaScript, the document object is an instance of Document, which allows for querying and retrieval of nodes in a number of different ways.
• An Element node represents all HTML or XML elements in a document and can be used to manipulate their contents and attributes.
• Other node types exist for text contents, comments, document types, the CDATA section, and document fragments.
