Find direct child elements not grandchildren

Hi, I’ve been trying to find a way to get all direct child elements (not grandchildren) but without success. I’m using Appium 1.2 with ruby. The following command returns all descendant elements of the specified class: parentElement.find_elements(:class, “UIAStaticText”). What I want is to get all direct child elements of the given class. I also would like to know if there is a method to get all direct child elements regardless the class type (something like parentElement.find_elements(:path, “*”), which currently does not work). Thanks
