Working with the response DOM

Hi,

Anyone know a way to traverse/query the DOM in a response?

I'm trying to write reusable story step implementations and as much as possible want to work with the actual response from a previous GET.

As an example, I often have buttons that POST/PUT a hidden value.
My goal is a reusable step implementation that takes the button label and works the existing response DOM to make an appropriate POST/PUT.
