How to access DOM (and /or window.document object) of a popup in Chrome extension ?

[mstram]

I'm working on a Google Chrome 'context' script

From the Chrome console, or a 'normal' tag, I can do :

win1 = window.open('some url');
b1 = win1.document.body.innerHTML;

But from a chrome 'context' script, it fails with

Uncaught TypeError: Cannot read property 'document' of undefined

What is the "magic incantation" I need ?

This seems to be close to what I need, but it doesn't show where to
put code to have the popup return a dom element:

I don't fully understand the code there (nested scopes and things), so
I'm trying to figure out where I'd put something like:

var getStuff = $('#baz').html();

Maybe some one would like to write a blog post 'disecting' that
code ? :)

Anybody ???

I'd really like to get this going !

I've looked through all the code examples, and the closest thing is
the "mappy" thing, but it's using a pre-defined "popup", where I need
to access a varying url.

The mappy example also does not have the background page reading FROM
the popup, which is what I need.
