Unwanted page breaks during OTD to MOBI conversion

plznot · 04-16-2019, 06:43 AM

When I convert my OTD file to a MOBI file, Calibre automatically inserts a page break on every new header 1 and 2. My problem is that my book is structured somewhat like this

Chapter 1
1. Chapter 1.1
2. Chapter 1.2
3. ...
Chapter 2
1. Chapter 2.1
2. Chapter 2.2
3. ...
Chapter 3
1. Chapter 3.1
2. Chapter 3.2
3. ...
...

The title of x is always on a its own page with the title of x.1 and its content being on the next page.
I want there to be a page break at the start of a new chapter and a new subchapter, except x.1, without removing x.1 from the index.
How do I accomplish that?

Look in the structure detection section of the conversion dialog.

I've already looked there. But since I have no idea how XPath expressions works and the other options don't help me in any way, it was a dead end for me.

To be more precise, I don't see a way to specify that I don't want it to create a page break on x.1 but do create one on x, x.2, x.3, ...

You just want to reduce the trigger conditions
Since 'Chapter' is in Both, something else must change: That could be making sub chapters H2 and removing that break condition (remember you style using the CSS, not the heading level numbers ( way

)

Code:

Structure detection (on the conversion dialog, NOT preferences, which is FUTURE defaults) 

Insert Page breaks

	Code:
	//*[name()='h1' or name()='h2']

So I would have to manually change 1.1, 2.1, 3.1, ... to h2? I don't object, but I am not sure whether or not it's possible for an ODT document in LibreOffice. (at least I couldn't find how)

Is there a way to to a exclude something from an XPath match?
In Regex I would match

Code:

Chapter \d*(?!.)|Chapter \d*\.(?!1)\d*

and thus exclude the subchapters I don't want to have a page break on.
From what I can see XPath is too limited in features to do that though.

@plznot IMO it's best to do as much as possible in LO. If you learn how to use its template and style features you will have less fiddling and editing to do after any conversions, see ==>> Libre Office: Using Styles and Templates.

Using Styles rather than inline styling will also result in much neater code in the conversion output. And, I recommend saving as DOCX and converting that. The DOCX input module does a better job than its ODT equivalent, and its actively maintained by Kovid Goyal (calibre creator/owner).
