No, I'm a stranger in a strange land - not sure of anything except the value of the information in those screwed up documents.
I entered this <h3 class="calibre7">
9 </h3><p class="calibre2"> and did repetitive search/replace while changing that
single digit, replacing the whole string with a space. Looks pretty good, but I might have to do this many times so would welcome a more efficient solution.
