The Document Object Model (DOM):

• Is a programming interface for XML documents.
• Defines how XML documents can be programmatically accessed and manipulated.
• Is a platform- and language-neutral interface.
• Represents an XML document as a tree structure.
• Provides access to XML document structure through a set of objects.
• Defines an API for accessing and manipulating XML documents.

Writing an application that accesses an XML document through DOM requires:

• An XML Parser
• DOM

Using DOM to create and manipulate XML documents helps avoid:

• Unclosed tags
• Improperly nested tags

DOM helps easily move information between a database and an XML file.
