I can think of two things that can do the job:

1) HTTP proxy.

Squid may be able to pull the trick you want, but I'm unsure of that.
Nginx (configured as a conventional proxy) can do it via
mod-http-xslt-filter, but writing nginx.conf for this will be a PITA.

2) Client-side javascript invoking needed XSLT transformation.

The extension you need is called Greasemonkey for Firefox and
Violentmonkey for Chromium.
An approach requires minimal knowledge of Javascript.
