Ah, you also need to avoid doing the replacement when the word appears
in an HTML attribute. For example:
<a href="http://www.google.pl/search?q=car"> ... </a>
A simple search and replace, even with regular expression, isn't going
to work always. You will need to parse the HTML to some degree. Where
is this text coming from? HTML that can contain Javascript will
require a full-fledge parser.
