public:
virtual System::Xml::XmlWriter ^ ReplaceRange(System::Xml::XPath::XPathNavigator ^ lastSiblingToReplace);
public virtual System.Xml.XmlWriter ReplaceRange (System.Xml.XPath.XPathNavigator lastSiblingToReplace);
abstract member ReplaceRange : System.Xml.XPath.XPathNavigator -> System.Xml.XmlWriter
override this.ReplaceRange : System.Xml.XPath.XPathNavigator -> System.Xml.XmlWriter
Public Overridable Function ReplaceRange (lastSiblingToReplace As XPathNavigator) As XmlWriter
參數
- lastSiblingToReplace
- XPathNavigator
XPathNavigator,位於要取代的範圍內的最後一個同層級節點上。
傳回
用來指定取代範圍的 XmlWriter 物件。
例外狀況
指定的 XPathNavigator 為 null
。
指定為要取代的最後一個節點不是目前節點的有效同層級節點。
範例
在下列範例中,檔案的第一個和第二 book
個元素 contosoBooks.xml
會使用 ReplaceRange 方法,以新的空白 book
元素取代。
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);
XmlWriter^ newRange = navigator->ReplaceRange(last);
newRange->WriteStartElement("book");
newRange->WriteAttributeString("genre", "");
newRange->WriteAttributeString("publicationdate", "2005-04-07");
newRange->WriteAttributeString("ISBN", "0");
newRange->WriteStartElement("title");
newRange->WriteString("New Book");
newRange->WriteEndElement();
newRange->WriteStartElement("author");
newRange->WriteStartElement("first-name");
newRange->WriteString("First Name");
newRange->WriteEndElement();
newRange->WriteStartElement("last-name");
newRange->WriteString("Last Name");
newRange->WriteEndElement();
newRange->WriteEndElement();
newRange->WriteElementString("price", "$0.00");
newRange->WriteEndElement();
newRange->Close();
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);
XmlWriter newRange = navigator.ReplaceRange(last);
newRange.WriteStartElement("book");
newRange.WriteAttributeString("genre", "");
newRange.WriteAttributeString("publicationdate", "2005-04-07");
newRange.WriteAttributeString("ISBN", "0");

newRange.WriteStartElement("first-name");
newRange.WriteString("First Name");
newRange.WriteEndElement();
newRange.WriteStartElement("last-name");
newRange.WriteString("Last Name");
newRange.WriteEndElement();
newRange.WriteEndElement();
newRange.WriteElementString("price", "$0.00");
newRange.WriteEndElement();
newRange.Close();
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)
Dim newRange As XmlWriter = navigator.ReplaceRange(last)
newRange.WriteStartElement("book")
newRange.WriteAttributeString("genre", "")
newRange.WriteAttributeString("publicationdate", "2005-04-07")
newRange.WriteAttributeString("ISBN", "0")
newRange.WriteStartElement("title")
newRange.WriteString("New Book")
newRange.WriteEndElement()
newRange.WriteStartElement("author")
newRange.WriteStartElement("first-name")
newRange.WriteString("First Name")
newRange.WriteEndElement()
newRange.WriteStartElement("last-name")
newRange.WriteString("Last Name")
newRange.WriteEndElement()
newRange.WriteEndElement()
newRange.WriteElementString("price", "$0.00")
newRange.WriteEndElement()
newRange.Close()
Console.WriteLine(navigator.OuterXml)
