Cleaning a book that someone has converted through Calibre a number of times.
Mostly a lot of grunt work, but I've come across the following many times, not only in this one but many others. The chapter number is H1, so the TOC just consists of a string of numbers
So if I can save the F&R in Tools, I can use it whenever I need it
Looks like this ..
<p>TITLE OF CHAPTER</p>
After manually making changes (lots of trial and error), this seems to work best
TITLE OF CHAPTER</h1>
or if I could be even more clever
Title Of Chapter</h1>
