Is it possible to intercept/handle/parse the HTML inside of the body tags before the browser?
<p>I'm wondering if it is at all possible to take whatever is inside of the  tags, run it through Javascript and manipulate it before throwing it back for the browser to then parse.</p>

<p>I'm sure it can be done, however it may not be as straightforward as I am suggesting.</p>

<p>For instance, is there a way for the Javascript to take the entire source code of the HTML file and put it into a var as text?</p>
