XmlNamespaceManager Constructor

Initializes a new instance of the XmlNamespaceManager class with the specified XmlNameTable.

Namespace:  System.Xml
Assembly:  System.Xml (in System.Xml.dll)
public XmlNamespaceManager(
	XmlNameTable nameTable


Type: System.Xml.XmlNameTable
The XmlNameTable to use.

nameTable is null.

The name table is used to look up prefixes and namespaces. An existing name table with pre-atomized strings can be specified in the constructor. There are several advantages in doing so. For example, if the name table of an XmlReader object is used, after each read, any namespace and prefix strings pushed into the name table can be re-used by XmlNamespaceManager.

For more information on atomized strings, see XmlNameTable.


If you specify an existing name table, any namespaces in the name table are not automatically added to XmlNamespaceManager. You must use AddNamespace and RemoveNamespace to add or remove namespaces.

                StringBuilder output = new StringBuilder();

                // Create the string containing the XML to read.
                String xmlFrag =
		                        <item id='1'>

                using (XmlReader reader = XmlReader.Create(new StringReader(xmlFrag)))
                    XmlNamespaceManager nsmanager = new XmlNamespaceManager(reader.NameTable);
                    nsmanager.AddNamespace("msbooks", "www.microsoft.com/books");
                    nsmanager.AddNamespace("msstore", "www.microsoft.com/store");

                    foreach (String prefix in nsmanager)
                        output.AppendLine("Prefix" + prefix + " Namespace=" +
                OutputTextBlock.Text = output.ToString();
