XmlNamespaceManager.PopScope Method

Pops a namespace scope off the stack.

Namespace: System.Xml
Assembly: System.Xml (in system.xml.dll)

public virtual bool PopScope ()
public boolean PopScope ()
public function PopScope () : boolean

Return Value

true if there are namespace scopes left on the stack; false if there are no more namespaces to pop.

When you call this method, all namespaces which were added to XmlNamespaceManager (by calling AddNamespace) since the last call to PopScope are removed.

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);
  }

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