why not strip them before storing the html content into the DB?
that way you need to strip them only once, while if you strip them on
display you need to strip them once for each request.
and you don't need checking with <pre> tags and stuff.
just do a
str_replace(array("\n", "\r", "\t"), "", $text);
on it and that's all
