Using VI I edit some files in which I want to erase many lines I don't need anymore
usually I do something like that:
and it is doing fine
but in this case, the pattern to erase contains some special characters

but, the only problem left is that I can't predict what will be the beginning of the line so I wish I could do something like that:
but of course if I protect the pattern with # to prevent special characters to annoy me... the * don't work anymore
the best way would be to suppress each line containing my pattern, but I don't know how to do that
I'm sure it's pretty easy for many among you, so if one have a bit of time, it would help me a lot

I don't want to have to resort to
/()/
though that does work.
Effectively, I need to be able to implement
/(?:(?:regexp1){0})(regexp2)\D/
to basically match regexp2 as long as it is present and regexp1 is NOT.
So, how to do
/(regexp){0}/
