XmlNode.CreateNavigator Method

Creates an XPathNavigator for navigating this object.

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

public virtual XPathNavigator CreateNavigator()

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.

Implements

IXPathNavigable.CreateNavigator()

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.

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);
XmlDocument* doc = new XmlDocument();
doc -> Load(S"books.xml");

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

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

// Transform the file.
XslTransform* xslt = new XslTransform();
xslt -> Load(S"output.xsl");
XmlTextWriter* writer = new XmlTextWriter(S"books.html", 0);
xslt -> Transform(nav, 0, writer, 0);
