Delete some lines with some exceptions

I have several hundred file path names in a buffer, each filling a line, e.g. created with vim tip # 659.
About half of them are help files, starting with './help/' which I want to delete, but I want to keep the german ones, starting with './help/de/'. Here comes how I do it with Vim:
:global:^./help/:if (match(getline(line(".")), '^./help/de/') == -1) | delete | endif
Would this also do it?
No, because lines like
are not deleted. Instead use
to delete all lines starting with './help/' but keep all lines starting with './help/de/'
This will only work if each line in the file starts with './help'.
