broken chapters in an ebook about ebooklib

[vinniec]

Okay, small update, I fixed the table of contents with calibre, although the problem remains, you lose enough time to fix it by hand and it would be nice if you could merge chapter text automatically respecting the toc.

I am writing to add one thing though, in another book I adjusted the toc to add subchapters and this though generated an error in ebooklib which I am sharing:

piece of code

book = epub.read_epub("book.epub")
for a in book.toc:
    print(type(a))
    print(type(a.title), a.title)

output with error

....
<class 'ebooklib.epub.Link'>
<class 'str'> CAP TITLE
<class 'tuple'>
Traceback (most recent call last):
  File "<string>", line 11, in <module>
AttributeError: 'tuple' object has no attribute 'title'

you can see that the object from class ebooklib.epub.Link becomes a tuple that does not contain the title property

If it is not a problem could you send me sample of your input and output files to my email [email protected] so I can double check what is going on there. I want to check how is TOC organised in the original book.

ok i re-sent you an email :)

@aerkalov I have a related issue/question (but let me know if I should open a separate issue):

I am trying to map the chapter/section info from the TOC to text elements for partitioning epub books. I've noticed a few things...

1. the TOC hrefs can refer to the same epub.EpubHtml item from book.items
2. some book.items are skipped by the TOC hrefs
3. the beginning and ending of an epub.EpubHtml.get_content object doesn't line up with the beginning and ending of chapters.

Looking at the epub.EpubNcx, I'm wondering if it's somehow possible to use the links to define the chapter boundaries, but I haven't been able to figure it out. Any help would be greatly appreciated!
This is the book I'm using for testing: https://www.gutenberg.org/cache/epub/60153/pg60153-images.html#CONTENTS
