How to xpath for element with two possible last element?

Question

I have complex xpath selector. I want to make it generic, so it could point to input and textarea.

example xpath's

//someelement//input

//someelement//textarea

how to merge those two into single xpath?

Answer 1

You can use an union:

 //someelement//input  | //someelement//textarea

Or in XPath 2:

//someelement//(input, textarea)
