I have just completed editing an EPUB to get the chapters etc right and then converted it to KEPUB. I then Exploded and Examined the Kepub and came across some strange results.

I had split the epub into Chapters which started with a h2 header with the text "CHAPTER n" followed by another h2 header with a subtitle text e.g. "Our Hero Goes Forth".

When I convert this to kepub the chapters are split so section_004.html becomes section_004_split_001.html and section_004_split_002.html with the first file containing just the CHAPTER n heading and the second one the rest of the original. Needless to say this means that when rendered on the Glo the combining I had done is undone and CHAPTER n will appear on a separate page.

I checked that I have nothing in the "Detect Chapters" xpath under "Stucture Detection" in the conversion options.

From the conversion log it appears that this is where the splitting is happening :

Code:

Splitting markup on page breaks and flow limits, if any...
Splitting on page-break at id=calibre_pb_18
Splitting on page-break at id=calibre_pb_19
Splitting on page-break at id=calibre_pb_20

This is the code in the original html which is triggering the split :

Code:

<h2 class="calibre23" id="calibre_pb_18"><span class="calibre18"><span class="bold"><span><a class="calibre15" href="../Text/Nation_002.html#filepos1740"><span class="calibre16"><span><span class="bold">CHAPTER 3</span></span></span></a></span></span></span></h2>

I'm unclear as to why these are being treated as pagebreaks - AIUI the id is just reference.

Is this a bug that needs reporting or have I missed some obscure option ?

EDIT: I've looked at another conversion and it looks like the page split is happening on all id= ocurrences

EDIT2 : Found the option for "Do Not Split on Page Breaks" - if selected this stops the unwanted splitting, however why all id's are being treated as page breaks is less than obvious. I suspect this is not a function of the Kepub conversion but of Calibre's EPUB routines.
