示例

以下示例使用 OuterXml 该属性显示文件中第一个 book 元素 contosoBooks.xml 的内容、其子节点以及文件中 XPathNavigator的开始和结束标记。

XPathDocument^ document = gcnew XPathDocument("contosoBooks.xml");
XPathNavigator^ navigator = document->CreateNavigator();

navigator->MoveToChild("bookstore", "http://www.contoso.com/books");
navigator->MoveToChild("book", "http://www.contoso.com/books");

Console::WriteLine(navigator->OuterXml);

XPathDocument document = new XPathDocument("contosoBooks.xml");
XPathNavigator navigator = document.CreateNavigator();

navigator.MoveToChild("bookstore", "http://www.contoso.com/books");
navigator.MoveToChild("book", "http://www.contoso.com/books");

Console.WriteLine(navigator.OuterXml);

Dim document As XPathDocument = New XPathDocument("contosoBooks.xml")
Dim navigator As XPathNavigator = document.CreateNavigator()

navigator.MoveToChild("bookstore", "http://www.contoso.com/books")
navigator.MoveToChild("book", "http://www.contoso.com/books")

Console.WriteLine(navigator.OuterXml)

该示例使用 contosoBooks.xml 文件作为输入。

注解

备注

属性InnerXmlOuterXml并不十分高效。 如果性能是优先级，则使用子节点的节点导航方法 XPathNavigator 获取子节点的值更有效。
