Public Overridable Function MoveToFollowing (type As XPathNodeType, end As XPathNavigator) As Boolean

参数

type
XPathNodeType

元素 XPathNodeType 的元素。 不能XPathNodeTypeAttribute或 Namespace。

end
XPathNavigator

XPathNavigator定位在元素边界上的对象，当前XPathNavigator在搜索以下元素时不会移动。

返回

Boolean

true 如果成功移动， XPathNavigator 则为 ：否则为 false。

示例

在以下示例中，将 XPathNavigator 文件根 contosoBooks.xml 目录移动到以下 price 元素。 使用XPathNavigator该方法克隆Clone对象。 克隆 XPathNavigator的，定位在 price 元素上，将用作边界。 克隆 XPathNavigator 位置的更改不会影响原始 XPathNavigator内容。 原始XPathNavigator文件使用contosoBooks.xml该方法移回文件的根MoveToRoot目录。 使用方法和 <a0/> 检索作者的标题和名字和姓氏。 此方法 MoveToFollowing 将返回 true， price 直到达到元素边界。

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

navigator.MoveToFollowing("price", "http://www.contoso.com/books");
XPathNavigator boundary = navigator.Clone();

navigator.MoveToRoot();

while (navigator.MoveToFollowing(XPathNodeType.Text, boundary))
{
    Console.WriteLine(navigator.OuterXml);
}

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

navigator.MoveToFollowing("price", "http://www.contoso.com/books")
Dim boundary As XPathNavigator = navigator.Clone()

navigator.MoveToRoot()

While navigator.MoveToFollowing(XPathNodeType.Text, boundary)
    Console.WriteLine(navigator.OuterXml)
End While

该示例将 contosoBooks.xml 文件作为输入。

注解

  • XPathNavigator如果作为参数传递的边界在当前XPathNavigator位置之后未定位，则忽略该边界。

  • 如果边界参数为XPathNavigator，则指定本地名称和命名空间 URI 的null以下元素按文档顺序排列。

  • 方法 MoveToFollowing 不能用于移动到属性或命名空间节点。 如果将作为参数传递的 XPathNavigator 边界定位在属性或命名空间节点上，则它等效于 XPathNavigator 已定位在其父元素的第一个子节点上的边界参数。 这可确保边界参数定位到的属性或命名空间节点 XPathNavigator 的父元素可由此方法匹配。

  • MoveToFollowing如果方法返回false，则位置XPathNavigator不变。
