While it's a little hard to determine the particulars from your
description and pseudo-examples, the general process I use to do
something similar looks like
:g/interesting/sil! ?start?,/end/s/^/XXX/
:v/^XXX/d
:%s/^XXX
This searches for every line matching the pattern "interesting",
then searches backwards for the pattern "start" as the beginning
of the range, and forward to the pattern "end". With each of
those start...end ranges, it tacks on a unique prefix (in this
case, "XXX") The "sil!" is just to prevent it from reporting
action on every matching line because it annoys me :)
Now that you've found and marked the interesting stuff, you can
delete the rest (the "v/^XXX/d").
Finally, remove the "XXX" marker leaving you with just what you want.
Each of those patterns can be an arbitrary regexp, so you can use
multiple conditions:
:g/foo\|bar\|baz/sil! ...
Alternatively, I'll use ">" as my command instead of "s/^/XXX" to
indent the lines of interest (best done with 'noet' and 'sw'='ts'
so you get one tab of indent), delete the non-indented lines, and
then un-indent the indented lines:
:g/interesting/sil! ?start?,/end/>
:v/^\t/d
:%<
Hope this gives you a general pattern you can use.
