FIX: XPathNavigator.MoveToNextNamespace with XPathNamespaceScope.Local (316808)

MORE INFORMATION

Steps to Reproduce Behavior

1. Create a new empty Microsoft Visual C# project, and be sure to add a reference to the System.XML namespace to the empty project.
2. Paste the following code in a new file and and save it as Q316808.cs. (The file name can be any valid name).

   using System;
   using System.Xml;
   using System.Xml.XPath;
   using System.Diagnostics;
   
   namespace XmlTest
   {
   	class Class1
   	{
   		[STAThread]
   		static void Main(string[] args)
   		{
   			// Create document.
   			string xml = "<ns1:myElement xmlns:ns1='http://namespace1' xmlns:ns2='http://namespace2'><ns1:someElement/></ns1:myElement>";
   			XmlDocument doc = new XmlDocument();
   			doc.LoadXml(xml);
   
   			// Create XPath navigator.
   			XPathNavigator nav = doc.CreateNavigator();
   			
   			Console.WriteLine("Checking navigator\r\n");
   
   			// Reproduce the problem.
   			nav.MoveToRoot();
   			Console.WriteLine("MoveToFirstChild = " + nav.MoveToFirstChild().ToString());
   			Console.WriteLine("Name = " + nav.Name);
   			Console.WriteLine("MoveToFirstNamespace = "+ nav.MoveToFirstNamespace(XPathNamespaceScope.Local).ToString());
   			Console.WriteLine("NodeType = "+ nav.NodeType.ToString());
   			Console.WriteLine("Name = "+ nav.Name);
   			Console.WriteLine("MoveToNextNamespace = "+ nav.MoveToNextNamespace(XPathNamespaceScope.Local).ToString());
   			Console.WriteLine("NodeType = "+ nav.NodeType.ToString());
   			Console.WriteLine("Name = "+ nav.Name);
   
   			Console.WriteLine("\r\n\r\nExpected Results \r\n\r\n");
   			nav.MoveToRoot();
   			Console.WriteLine("MoveToFirstChild = " + nav.MoveToFirstChild().ToString());
   			Console.WriteLine("Name = " + nav.Name);
   			Console.WriteLine("MoveToFirstNamespace = "+ nav.MoveToFirstNamespace().ToString());
   			Console.WriteLine("NodeType = "+ nav.NodeType.ToString());
   			Console.WriteLine("Name = "+ nav.Name);
   			Console.WriteLine("MoveToNextNamespace = "+ nav.MoveToNextNamespace().ToString());
   			Console.WriteLine("NodeType = "+ nav.NodeType.ToString());
   			Console.WriteLine("Name = "+ nav.Name);		
   
   		}
   	}
   }
   					

3. Compile the project, and then set a breakpoint at the end of the Main function. On the Debug menu, click Start (or just press F5), and you should see the following output from the console window:
   Checking navigator
   
   MoveToFirstChild = True
   Name = ns1:myElement
   MoveToFirstNamespace = True
   NodeType = Namespace
   Name = ns2
   MoveToNextNamespace = False
   NodeType = Element
   Name = ns1:myElement
   
   Expected Results :
   
   MoveToFirstChild = True
   Name = ns1:myElement
   MoveToFirstNamespace = True
   NodeType = Namespace
   Name = ns2
   MoveToNextNamespace = True
   NodeType = Namespace
   Name = ns1
