Remarks

XPathNavigator is based on the XPath data model and provides the methods required to implement XPath queries over any data store. To create an XPathNavigator over an XML document or a DataSet (using the XmlDataDocument class), use the CreateNavigator method available in the XmlNode and XPathDocument classes, which implement the IXPathNavigable interface. Additionally, you can create your own implementation of XPathNavigator over other data stores such as file systems or databases. For more information on implementing your own XPathNavigator, see XPathNavigator over Different Stores.

XPathNavigator provides read-only, random access to data. The current node refers to the node on which the navigator is positioned. The navigator is advanced using any of the move methods and properties reflect the value of the current node. If the navigator is created by XmlDocument, you can use the IHasXmlNode.GetNode method to return the XmlNode representing the current position of the navigator.

XPathNavigator supports XSLT and can be used as an input mechanism to the XslTransform.Transform method.

For more information on the XPath data model, see the W3C XML Path Language (XPath) recommendation located at http://www./TR/xpath.
