If these sections are truly nested, in other words "1st Section"
elements are section headings and "2nd Section" elements are
sub-section headings and "3rd section" elements are sub-sub-section
headings, etc., then what I wrote earlier has to be modified.

The modification required depends a good deal on the structure:
Are there always 4 levels of sections?
Is the first element after, for example, a 1st Section element always
a 2nd section element, or can you have some body text summarizing the
section before the sub-section begins, etc?

Feel free to send me an abbreviated/redacted version of the file you
are looking at, and I'll give it a go sometime.
