範例

以下範例中，檔案的第一book和第二contosoBooks.xml元素會用該DeleteRange方法被刪除。

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)

此範例會將 contosoBooks.xml 檔案當作輸入。
