XmlNode.CreateNavigator Method

Creates an XPathNavigator for navigating this object.

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

Public Overridable Function CreateNavigator As XPathNavigator

Return Value

Type: System.Xml.XPath.XPathNavigator
An XPathNavigator object. The XPathNavigator is positioned on the node from which the method was called. It is not positioned on the root of the document.



The XPathNavigator provides read-only, random access to data. Because it is optimized for XSLT transformations, it provides performance benefits when used as an input mechanism to the XslTransform.Transform method.

This method is a Microsoft extension to the Document Object Model (DOM).

The following example loads and edits an XML document before performing an XSLT transform.

Dim doc as XmlDocument = new XmlDocument()

' Modify the XML file.
Dim root as XmlElement = doc.DocumentElement
root.FirstChild.LastChild.InnerText = "12.95"

' Create an XPathNavigator to use for the transform.
Dim nav as XPathNavigator = root.CreateNavigator()

' Transform the file.
Dim xslt as XslTransform = new XslTransform()
Dim writer as XmlTextWriter = new XmlTextWriter("books.html", nothing)
xslt.Transform(nav,nothing, writer, nothing)
