First, if this is the actual HTML snippet, it is REALLY ugly. Having the INPUT tag nested 6 DIVs deep looks like finding the right locator is only part of the problem. If I had to automate this HTML I would have a serious talk with the developer who generated it. It looks like they don't have a proper grasp of the library they are using to generate it. 

Ignoring all the garbage around the INPUT tag you should be able to use:

    By.xpath("//input[contains(text(), 'AAA_Automation')]");
