Public Overridable Sub PushScope ()

Examples

The following example adds prefix/namespace pairs to the XmlNamespaceManager and then displays all the pairs in the collection.

using System;
using System.IO;
using System.Xml;

public class Sample
{
 public static void Main()
 {
 Sample test = new Sample();
 }
 public Sample()
 {
 // Create the XmlNamespaceManager.
 NameTable nt = new NameTable();
 XmlNamespaceManager nsmgr = new XmlNamespaceManager(nt);

 // Add prefix/namespace pairs to the XmlNamespaceManager.
 nsmgr.AddNamespace("", "www.wideworldimporters.com"); //Adds a default namespace.
 nsmgr.AddNamespace("europe", "www.wideworldimporters.com/europe");
 nsmgr.PushScope(); //Pushes a namespace scope on the stack.
 nsmgr.AddNamespace("", "www.lucernepublishing.com"); //Adds another default namespace.
 nsmgr.AddNamespace("partners", "www.lucernepublishing.com/partners");

 Console.WriteLine("Show all the prefix/namespace pairs in the XmlNamespaceManager...");
 ShowAllNamespaces(nsmgr);
 }

 private void ShowAllNamespaces(XmlNamespaceManager nsmgr)
 {
 do{
 foreach (String prefix in nsmgr)
 {
 Console.WriteLine("Prefix={0}, Namespace={1}", prefix,nsmgr.LookupNamespace(prefix));
 }
 }
 while (nsmgr.PopScope());
 }
}

Remarks

After a call to this method, all namespaces, which are added to XmlNamespaceManager (by calling AddNamespace), belong to the pushed namespace scope.
