Examples

The following example displays the xml:lang value for each of the nodes.

#using <System.Xml.dll>

using namespace System;

   // Create the XML fragment to be parsed.

   // Create the XmlNamespaceManager.
   NameTable^ nt = gcnew NameTable;
   XmlNamespaceManager^ nsmgr = gcnew XmlNamespaceManager( nt );
   
   // Create the XmlParserContext.
   XmlParserContext^ context = gcnew XmlParserContext( nullptr,nsmgr,nullptr,XmlSpace::None );
   
   // Create the reader.
   XmlTextReader^ reader = gcnew XmlTextReader( xmlFrag,XmlNodeType::Element,context );
   reader->WhitespaceHandling = WhitespaceHandling::None;
   
   // Parse the XML and display each of the nodes, including the xml:lang setting.
   while ( reader->Read() )

Remarks

Note

Starting with the .NET Framework 2.0, we recommend that you create XmlReader instances by using the XmlReader.Create method to take advantage of new functionality.

This property represents the xml:lang scope within which the current node resides. For example, here is an XML fragment with xml:lang set to US English in the root element:

<root xml:lang="en-us">

<name>Fred</name>

</root>

When the reader is positioned on the name element, you can use this property to find that it is in the scope of a US English xml:lang attribute.
