此 API 支持产品基础结构,不能在代码中直接使用。

public value class XPathPrecedingIterator
public struct XPathPrecedingIterator
type XPathPrecedingIterator = struct
Public Structure XPathPrecedingIterator
继承

注解

XPath 前面的轴规则指定不包含祖先, 即使它们按文档顺序在开始节点之前。The XPath preceding axis rules specify that ancestors are not included, even though they precede the starting node in document order.

属性
