Ideally it would be great to delete all other content from each

OK, thanks and in that case, you should be able to obtain the
desired outcome by performing a multi-file search & replace with
"Grep" enabled and patterns like these:
Find: \A(?s).+?(<div class="main-content">(?s).+?</div>)(?s).+
Replace: \1
and in short, here's how the patterns work:
The Find pattern begins by matching at the start of the document
\A and then _non-greedily_ matches ? one or more instances of
any character .+ _including_ line breaks (achieved by
pre-pending (?s) to the .) and followed by a single
_sub-pattern_, whose contents are enclosed in parentheses ( )
and consist of the opening div followed by one or more
characters in another non-greedy match across lines and then a
closing div, and finally matching any characters remaining in
the document, including line breaks (?s).+
[NB: You'll need to adjust the exact form of the desired
<div> to suit
your content, i.e. depending whether these sections are
identified by
'class', 'name', or 'id'.]
The Replace pattern then reinserts only the contents of the
matched subpattern (consisting of the desired div, its contents,
and the closing div), thus effectively deleting everything else.
As always, I recommend you try this procedure out on a few
sample files or a cloned copy before applying it to your actual
data, just to make sure it's doing what you expect/want. :-)
