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 programmer—for 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.
