Property Value
Type:
System..::.StringThe namespace prefix associated with the current node.
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.
