在以下示例中，使用
DeleteRange
该方法删除文件的第一个和第二个
book
元素
contosoBooks.xml
。

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)
该示例使用
contosoBooks.xml
文件作为输入。

该方法 DeleteRange 从当前节点中删除一系列同级节点，该 XPathNavigator 节点位于 (非独占) (非独占) 指定的 XPathNavigator 节点。 然后，该 XPathNavigator 节点位于其父节点上。
