You need it or want to set it?

If you need it in the http_request.reponseText string (ie that string
is/has some JavaScript) then just use document.body.innerHTML.

To set it

document.body.innerHTML = http_request.responseText;

I didn't see the subject line of your post at first. Won't this work?

/<body>(.)</body>/

You mean apart from the unescaped slash in the middle of the regex, the
fact that a dot only matches 1 character, and also that a dot won't match a
newline?

This would probably work most of the time:

/<body[^>]*>((?:.|\n)*)<\/body>/

Of course :) I suppose I was trying to figure out what is abnormal or
tricky about this RegExp question.

If the infix slash would be escaped, this would work if the body element
was a one-liner with one-non-whitespace-character content :)

You were looking for

req.responseText.match(/<body(?:\s+(?:.|\n)*?)?>((.|\n)*)<\/body>/)[1]

or a backwards-compatible substitute like

req.responseText.match(/<body(\s+[^>]*)?>((.|\n)*)<\/body>/)[2]
