`ends-with` function is defined in the W3C XPath 2.0 specification, but no browser support it. You can not use `ends-with` in Selenium tests.

But you can write an equivalent XPath expression using `substring` and `string-length` function of XPath1.0. Both functins are supported by any browser. See the following post for example:

> [@Unable to find the element located by 'By.xpath;](http://forum.katalon.com/t/unable-to-find-the-element-located-by-by-xpath/52826/7):
>
> You have this: //iframe[ends-with(@id,'iframe')] Unfortunately no browser supports the XPath 2.0 function ends-with(). It would never work. You can write an alternative expression using XPath 1.0 functions substring and string-length: //iframe[substring(@id, string-length(@id) - string-length('iframe') +1) = 'iframe']
