It really depends on how complex/simple the page is. If its small site with little context you can usually traverse from parent body ignoring classes/ids. However, for more complex sites changing class/id values on each build can certainly help make this a lot more challenging. Ideally changing the children counts to prevent things like $(body).children().children()[3].html().
