XPathNavigator.MoveToFirstNamespace Method

Moves the XPathNavigator to first namespace node of the current node.

Namespace:  System.Xml.XPath
Assembly:  System.Xml (in System.Xml.dll)

public bool MoveToFirstNamespace()

Return Value

Type: System.Boolean
Returns true if the XPathNavigator is successful moving to the first namespace node; otherwise, false. If false, the position of the XPathNavigator is unchanged.

The XPathNavigator class returns namespace nodes in reverse document order. Therefore, MoveToFirstNamespace essentially moves to the last namespace node in the current scope.

After the XPathNavigator has been moved to the namespace node, the Name property reflects the name of the namespace.

When the XPathNavigator is positioned on a namespace node, the methods MoveToNext, MoveToPrevious, and MoveToFirst are not applicable. These methods always return false and do not change the position of the XPathNavigator. Rather, you can call MoveToNextNamespace to move to the next namespace node.

After the XPathNavigator is positioned on an namespace node, call MoveToParent to move back to the element node.

For a definition of namespace nodes, see section 5.4 of the W3C XML Path Language (XPath) recommendation located at http://www.w3.org/TR/xpath#data-model.
