The basic technique of using folding for this is this:
set foldmethod=expr
set foldexpr=getline(v:lnum)=~'text to be folded'
To close all the folds, you can
set foldlevel=0
but I usually use zM to close all folds and zR to open all folds.
You could wrap that in a mapping and maybe a function to make it
easier to use. I usually type it out once, then use the command
line history and editing features to modify the pattern as needed.
