XML DOM objects

First we need to explain the various, common DOM objects that you will use with the MSXML DOM Object.

We will focus on the examples of these XML DOM objects shown in table:

Object name	Description
DOMDocument	This object represents the root of the XML file.
XML DOM Element	This object represents each element in the DOM- Document, namely the root, root element, and each other element.
XML DOM Node	This object represents a single Node in the document tree and includes support for data types, namespaces, DTDs, and XML Schemas.
XML DOM NodeList	Use this object to access (by name) and iterate through the XMLDOMNode collection.
XML DOM NamedNodeMap	Use this object to access and iterate through the attributes in an element.
XML DOM CDATASection	This object represents a section in the value of an ele ment that is closed in the CDATA section brackets, which are characters that cannot be parsed by the XML.
XML DOM Attribute	This object represents a single attribute Node for a given element.
XML DOM DocumentType	This object represents the Document Type (DTD) in an XML file.
XML DOM Entity	This object represents an entity in the DTD section of the XML file.
XML DOM ProcessingInstruction	This object represents a processing instruction found in the XML file.
XML DOM ParseError	This object returns detailed information about the last error, including the line number, character position, and a text description.
XMLHTTPRequest	This object enables you to establish a connection to a web server from your code and send put, get, and other standard HTML requests.

In our examples, we will refer to these objects using the names listed in table .
