Xpath “ends-with” does not work

问题

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\')]]\"

and this

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

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

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

Here\'s the part of source:

<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>

回答1:

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'
