节点名称上的 XPath 通配符 [英] XPath wildcards on node name

问题描述

我想从我的 XML 文件中获取一个节点，该节点有一个前缀，例如latest_"，但这可能会改变，我希望我的 XSLT 尽可能流畅.这是我要使用的 XPath:

I want to grab a node from my XML file, the node has a prefix such as "latest_", but this may change and I'm keen for my XSLT to be as fluid as possible. Here's the XPath I want to use:

/data/stats/*_cost

这应该匹配latest_cost、newest_cost、anything_cost，有没有办法做到这一点?

This should match latest_cost, newest_cost, anything_cost, is there a way of doing this?

干杯:-)

推荐答案

这是正确的 XPath 1.0 表达式，它在任何命名空间中选择名称的最后 5 个字符等于_cost"的元素.

This is the correct XPath 1.0 expression which selects an element with the last 5 character of name equal to "_cost" in any namespace.

/data/stats/*[substring(name(), string-length(name()) - 4) = '_cost']
