user-defined methods in Selenium

[Tony Chamberlain]

Is there any way to make user-defined Selenium methods?  For instance, in the version of Selenium we use there is no ends-with().  So I have to do something like

//input[substring(@id, string-length(@id) - string-length('_PHONE$1') +1) = '_PHONE$1'] instead of //input[ends-with('_PHONE$1')].

So if I could do something like (and this is just an example):

define my-ends-with(String endsWith) {

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

}

I am using Java and Eclipse and Chrome and Selenium.  The selenium version is the one with Chrome that does not have an ends-with().

Chrome == 67.0.3396.87

Java 1.8
