Thanks Idolse! I can work with html and xpath a bit, but I'm lost on this one. Here's what surrounds a typical "chapter":
<p class="calibre_33"><font size="4"><span class="italic"><span class="bold">Chapter 2</span></span></font></p><p class="calibre_31">
Not too sure what to do with that...?
I've also used a program called fanfictiondownloader to create a mobi of this same story, pulling it direct from the site where the material is hosted rather than the azw created from my friends doc. In this case, the chapters ARE being detected and creating pagebreaks. The code surrounding those "chapter's" are:
<p class="calibre11"><span class="calibre5"><span class="bold">Chapter 2</span></span></p><p class="calibre11"><span class="italic">
Also, are you saying that you cannot create a TOC in an azw to mobi conversion?
I really appreciate the time and help!
