Assembly: System.Xml (in System.Xml.dll)
The 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 object is created from a class that implements the IXPathNavigable interface such as the XPathDocument and XmlDocument classes. objects created by XPathDocument objects are read-only while objects created by XmlDocument objects can be edited. An object's read-only or editable status is determined using the CanEdit property of the class.
For more information about processing XML data using the XPath data model, see the Process XML Data Using the XPath Data Model topic.
Exceptions raised as a result of using the class, such as the XPathException class, may contain sensitive information that should not be exposed in untrusted scenarios. Exceptions should be properly handled so that this sensitive information is not exposed in untrusted scenarios.
When you inherit from the class, you must override the following members:
Windows 7, Windows Vista, Windows XP SP2, Windows XP Media Center Edition, Windows XP Professional x64 Edition, Windows XP Starter Edition, Windows Server 2008 R2, Windows Server 2008, Windows Server 2003, Windows Server 2000 SP4, Windows Millennium Edition, Windows 98
