virtual void DeleteRange(System::Xml::XPath::XPathNavigator ^ lastSiblingToDelete);
public virtual void DeleteRange (System.Xml.XPath.XPathNavigator lastSiblingToDelete);
abstract member DeleteRange : System.Xml.XPath.XPathNavigator -> unit
override this.DeleteRange : System.Xml.XPath.XPathNavigator -> unit
Public Overridable Sub DeleteRange (lastSiblingToDelete As XPathNavigator)
- lastSiblingToDelete
- XPathNavigator
An XPathNavigator positioned on the last sibling node in the range to delete.
The XPathNavigator specified is null
.
The XPathNavigator does not support editing.
The last node to delete specified is not a valid sibling node of the current node.
In the following example, the first and second book
elements of the contosoBooks.xml
file are deleted using the DeleteRange method.
XmlDocument^ document = gcnew XmlDocument();
document->Load("contosoBooks.xml");
XPathNavigator^ navigator = document->CreateNavigator();
XmlNamespaceManager^ manager = gcnew XmlNamespaceManager(document->NameTable);
manager->AddNamespace("bk", "http://www.contoso.com/books");
XPathNavigator^ first = navigator->SelectSingleNode("/bk:bookstore/bk:book[1]", manager);
XPathNavigator^ last = navigator->SelectSingleNode("/bk:bookstore/bk:book[2]", manager);
navigator->MoveTo(first);
navigator->DeleteRange(last);
Console::WriteLine(navigator->OuterXml);
XmlDocument document = new XmlDocument();
document.Load("contosoBooks.xml");
XPathNavigator navigator = document.CreateNavigator();
XmlNamespaceManager manager = new XmlNamespaceManager(document.NameTable);
manager.AddNamespace("bk", "http://www.contoso.com/books");
XPathNavigator first = navigator.SelectSingleNode("/bk:bookstore/bk:book[1]", manager);
XPathNavigator last = navigator.SelectSingleNode("/bk:bookstore/bk:book[2]", manager);
navigator.MoveTo(first);
navigator.DeleteRange(last);
Console.WriteLine(navigator.OuterXml);
Dim document As XmlDocument = New XmlDocument()
document.Load("contosoBooks.xml")
Dim navigator As XPathNavigator = document.CreateNavigator()
Dim manager As XmlNamespaceManager = New XmlNamespaceManager(document.NameTable)
manager.AddNamespace("bk", "http://www.contoso.com/books")
Dim first As XPathNavigator = navigator.SelectSingleNode("/bk:bookstore/bk:book[1]", manager)
Dim last As XPathNavigator = navigator.SelectSingleNode("/bk:bookstore/bk:book[2]", manager)
navigator.MoveTo(first)
navigator.DeleteRange(last)
Console.WriteLine(navigator.OuterXml)
The example takes the contosoBooks.xml
file as an input.

The DeleteRange method deletes a range of sibling nodes from the current node the XPathNavigator is positioned on (inclusive) to the node specified by the XPathNavigator parameter (inclusive). The XPathNavigator is then positioned on its parent node.
