XPath:获取节点中最后一个兄弟节点的值 [英] XPath: Get value of last sibling in a node
问题描述
我正在尝试创建一个用于 MS InfoPath 的 XPath 表达式,以便检索节点中最后一个兄弟节点的值.(希望我能正确表达这个问题,因为我几乎没有使用过 XPath).
I am trying to create an XPath expression for use in MS InfoPath in order to retrieve the value of the last sibling in a node. (Hopefully I am phrasing this question correctly as I've barely ever used XPath).
我需要确定RepeaterGroup"节点内NamesEval"节点的最新实例.假设我会看看史蒂夫"是否参加了最新的活动;我将使用 contains(LatestEvent, "Steve")
XPath 表达式检查这一点.如何让LatestEvent"仅加载最新的NamesEval"值?
I need to identify the most recent instance of the "NamesEval" node inside the "RepeaterGroup" node. Hypothetically I will be looking to see if "Steve" is attending the latest event; I will check for this using a contains(LatestEvent, "Steve")
XPath expression. How do I get "LatestEvent" to load in only the most recent "NamesEval" value?

编辑 &答案
Choroba 回答了以下问题 - 这是解决方案://my:RepeaterGroup[0=count(following-sibling::my:RepeaterGroup)]//my:NamesEval
Choroba answered the question below - here is the solution: //my:RepeaterGroup[0=count(following-sibling::my:RepeaterGroup)]//my:NamesEval
推荐答案
我不确定我是否理解您的问题.如果您试图验证最后的 NamesEval 是否包含字符串Steve",您可以使用以下 XPath 表达式:
I am not sure I understand your question. If you are trying to verify that the last NamesEval contains the string "Steve", you can use the following XPath expression:
contains((//my:NamesEval)[last()],'Steve')
