Xpath的“结尾为"不起作用

问题描述

我正在尝试找到一个动态ID名称总是以"register"结尾的输入元素.到目前为止，我已经尝试过

I am trying to find an input element with dynamic id name always ending with "register". So far I tried this

"//input[@id[ends-with(.,'register')]]"

还有这个

"//input[ends-with(@id,'register')]"

这些都不是一个元素.我究竟做错了什么?同时可行:

none of these result in an element. What am I doing wrong? At the same time this works:

"//input[@id[contains(.,'register')]]"

这是来源的一部分:

<td class="input">
<input id="m.f0.menu.f2.volumeTabs.BLOCK_COMMON.tcw.form.register" name="m.f0.menu.f2.volumeTabs.BLOCK_COMMON.tcw.form.register" class="aranea-checkbox" type="checkbox"> </td>

推荐答案

ends-with函数是xpath 2.0的一部分，但浏览器(表明您正在使用chrome测试)通常仅支持1.0.因此，您必须自己结合string-length，substring和equals

The ends-with function is part of xpath 2.0 but browsers (you indicate you're testing with chrome) generally only support 1.0. So you'll have to implement it yourself with a combination of string-length, substring and equals

substring(@id, string-length(@id) - string-length('register') +1) = 'register'
