When overridden in a derived class, gets the namespace URI (as defined in the W3C Namespace specification) of the node on which the reader is positioned.
Namespace:
System.Xml
Assembly:
System.Xml (in System.Xml.dll)
Visual Basic (Declaration)
Public MustOverride ReadOnly Property NamespaceURI As String
Dim instance As XmlReader
Dim value As String
value = instance.NamespaceURI
public abstract string NamespaceURI { get; }
public:
virtual property String^ NamespaceURI {
String^ get () abstract;
}
public abstract function get NamespaceURI () : String
Property Value
Type:
System..::.StringThe namespace URI of the current node; otherwise an empty string.
This property is relevant to Element and Attribute nodes only.
The following example displays the local name of each node, and, if they exist, the prefix and namespace URI.
Dim reader As XmlReader = XmlReader.Create("book2.xml")
' Parse the file. If they exist, display the prefix and
' namespace URI of each node.
While reader.Read()
If reader.IsStartElement() Then
If reader.Prefix = String.Empty Then
Console.WriteLine("<{0}>", reader.LocalName)
Else
Console.Write("<{0}:{1}>", reader.Prefix, reader.LocalName)
Console.WriteLine(" The namespace URI is " + reader.NamespaceURI)
End If
End If
End While
reader.Close()
XmlReader reader = XmlReader.Create("book2.xml");
// Parse the file. If they exist, display the prefix and
// namespace URI of each node.
while (reader.Read()) {
if (reader.IsStartElement()) {
if (reader.Prefix==String.Empty)
Console.WriteLine("<{0}>", reader.LocalName);
else {
Console.Write("<{0}:{1}>", reader.Prefix, reader.LocalName);
Console.WriteLine(" The namespace URI is " + reader.NamespaceURI);
}
}
}
reader.Close();
The example uses the file, book2.xml, as input.
