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.

 public class  XmlDataDocument  : XmlDocument {  // Public Constructors  public  XmlDataDocument  ( );    public  XmlDataDocument  (System.Data.DataSet   dataset   );  // Public Instance Properties  public DataSet  DataSet  {get; }  // Public Instance Methods  public override XmlNode  CloneNode  (bool   deep   );  // overrides XmlDocument  public override XmlElement  CreateElement  (string   prefix   , string   localName   , string   namespaceURI   )  // overrides XmlDocument  public override XmlEntityReference  CreateEntityReference  (string   name   )  // overrides XmlDocument  public override XmlElement  GetElementById  (string   elemId   );  // overrides XmlDocument  public XmlElement  GetElementFromRow  (System.Data.DataRow   r   );    public DataRow  GetRowFromElement  (XmlElement   e   );    public override void  Load  (System.IO.Stream   inStream   );  // overrides XmlDocument  public override void  Load  (string   filename   );  // overrides XmlDocument  public override void  Load  (System.IO.TextReader   txtReader   );  // overrides XmlDocument  public override void  Load  (XmlReader   reader   );  // overrides XmlDocument   // Protected Instance Methods  protected override XPathNavigator  CreateNavigator  (XmlNode   node   )  // overrides XmlDocument  }
