A tweak to scottn's solution which does not consume blank lines, handles lines with multiple comments, and strongly quotes the exclamation point to protect it from history expansion on shells that support that feature:
Code:
$ cat data
some stuff
<!-- some comment-->
some more stuff <!-- some comment 2-->
<!-- some comment 3-->yet some more stuff
<!-- some comment 4-->yet even some more stuff<!-- some comment 5-->
$ sed -e '/^$/b' -e 's/<!--[^>]*>//g; /^$/d' data
some stuff
some more stuff
yet some more stuff
yet even some more stuff
It may be a no-brainer, but the answer is escaping me right now:
