Process XML Data Using the DOM Model

The XML Document Object Model (DOM) treats XML data as a standard set of objects and is used to process XML data in memory. The System.Xml namespace provides a programmatic representation of XML documents, fragments, nodes, or node-sets. It is based on the World Wide Web Consortium (W3C) DOM Level 1 Core and the DOM Level 2 Core recommendations.

The XmlDocument class represents an XML document. It includes members for retrieving and creating all other XML objects. Using the XmlDocument, and its related classes, you can construct XML documents, load and access data, modify data, and save changes.
