Provides a cursor model for navigating and editing XML data.

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

public ref class XPathNavigator abstract : public XPathItem, ICloneable, IXPathNavigable, IXmlNamespaceResolver
public abstract class XPathNavigator extends XPathItem implements ICloneable, IXPathNavigable, 
	IXmlNamespaceResolver
public abstract class XPathNavigator extends XPathItem implements ICloneable, IXPathNavigable, 
	IXmlNamespaceResolver

The XPathNavigator class in the System.Xml.XPath namespace is an abstract class which defines a cursor model for navigating and editing XML information items as instances of the XQuery 1.0 and XPath 2.0 Data Model.

An XPathNavigator object is created from a class that implements the IXPathNavigable interface such as the XPathDocument and XmlDocument classes. XPathNavigator objects created by XPathDocument objects are read-only while XPathNavigator objects created by XmlDocument objects can be edited. An XPathNavigator object's read-only or editable status is determined using the CanEdit property of the XPathNavigator class.

For more information about processing XML data using the XPath data model, see the Process XML Data Using the XPath Data Model topic.
