XmlNode.CreateNavigator XmlNode.CreateNavigator XmlNode.CreateNavigator XmlNode.CreateNavigator Method

Definition

Creates an XPathNavigator for navigating this object.

public:
 virtual System::Xml::XPath::XPathNavigator ^ CreateNavigator();
public virtual System.Xml.XPath.XPathNavigator CreateNavigator ();
abstract member CreateNavigator : unit -> System.Xml.XPath.XPathNavigator
override this.CreateNavigator : unit -> System.Xml.XPath.XPathNavigator
Public Overridable Function CreateNavigator () As XPathNavigator

Returns

An XPathNavigator object used to navigate the node. The XPathNavigator is positioned on the node from which the method was called. It is not positioned on the root of the document.

Implements

Examples

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

XmlDocument^ doc = gcnew XmlDocument;
doc->Load( "books.xml" );

// Modify the XML file.
XmlElement^ root = doc->DocumentElement;
root->FirstChild->LastChild->InnerText = "12.95";

// Create an XPathNavigator to use for the transform.
XPathNavigator^ nav = root->CreateNavigator();

// Transform the file.
XslTransform^ xslt = gcnew XslTransform;
xslt->Load( "output.xsl" );
XmlTextWriter^ writer = gcnew XmlTextWriter( "books.html", nullptr );
xslt->Transform( nav, nullptr, writer, nullptr);
XmlDocument doc = new XmlDocument();
doc.Load("books.xml");

// Modify the XML file.
XmlElement root = doc.DocumentElement;
root.FirstChild.LastChild.InnerText = "12.95";

// Create an XPathNavigator to use for the transform.
XPathNavigator nav = root.CreateNavigator();

// Transform the file.
XslTransform xslt = new XslTransform();
xslt.Load("output.xsl");
XmlTextWriter writer = new XmlTextWriter("books.html", null);
xslt.Transform(nav, null, writer, null);
Dim doc as XmlDocument = new XmlDocument()
doc.Load("books.xml")

' 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()
xslt.Load("output.xsl")
Dim writer as XmlTextWriter = new XmlTextWriter("books.html", nothing)
xslt.Transform(nav,nothing, writer, nothing)

Remarks

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).
