Thanks, Manichean! (Hey, my tutorial I found was written by you!)
Now, I'm not exactly sure what you meant by that so I'm assuming you are talking about the actual stuff inside the book file rather than the string of blank information that comes up before you click the wand (don't you love my very technical tech speak? lol). Sooo... I'll give you both.
The string in the space beside the wand (before clicking): (?i)(?<=<hr>)((\s*<a name=\d+></a>((<img.+?>)*<br>\s*)?\d+<br>\s*.*?\s*)|(\s*<a name=\d+></a>((<img.+?>)*<br>\s*)?.*?<br>\s*\d+))(?=<br>)
The header inside the file (after clicking the wand): <br>
5 <br>
<hr>
<A name=6></a><i>Delphine Dryden </i><br>
and
6 <br>
<hr>
<A name=7></a><i>When in Rio </i><br>
