Help with chapter detection

morgon · 03-24-2016, 09:30 PM

Hi,

I try to convert a rtf to epub and would like calibre to detect the chapters by regex.

The chapters are easily identified by starting with the chapter number, then a dot, followed by the chapter name in captitals (apart from A-Z the only character appearing in chapter names is an apostrophe.

So I use this:

Code:

//*[re:test(., "^\d+\. [ 'A-Z]+$")]

And this works - all chapters are detected but the problem I am having is that each chapter is added to the TOC twice.

Why is that?

Can anybody suggest a solution so that each chapter only appears in the TOC once?

Many thanks!

do you already have an inline TOC?

I managed to work around it by having a look at the debug-logs.

It seems that calibre converts input-files into an intermediate xhtml-format to which the xpath-selectors refer.

In my case I found that all the chapter-headings from the input-rtf where rendered as h1-tags, so I changed the selector to:

Quote:

//h:h1[re:test(., "^\d+\. [ 'A-Z]+$")]

And this works now. All chapters detected, only one entry in the TOC.

Unfortunately I still don't understand why the chapters appear twice with the above selector....

Oh well...
