System.Xml (system.data.dll)class

The XmlDataDocument is a marriage of XML and RDBMS technology; it is an XmlDocument-inheriting class that particularly understands ADO.NET DataSet objects. This offers a variety of opportunities to the .NET programmerfor example, a DataSet can be loaded into the XmlDataDocument, and then navigated using traditional DOM-style navigation using the XmlNode API. In fact, because XmlDataDocument also inherits the System.Xml.XPath.IXPathNavigable interface, XPath queries can be issued against the DataSet data, as well.

In order to build this relationship, construct the XmlDataDocument with the DataSet holding the data as its constructor parameter. Alternatively, use the Load( ) method to read in the data via an XmlReader. The resulting XML can also then be written out to another medium with the WriteTo( ) method.
