opening epub 3 on sigil

C-novice · 05-02-2018, 11:38 PM

I tried to open an epub 3 file in the latest Sigil version 0.9.9 and got this

Code:

The OPF file did not identify the NCX file correctly.
 - Sigil has used the following file as the NCX: toc.ncx

and the text appears with a bunch of tags in Book View.

What does that message mean and can this be fixed?

Most likely toc.ncx wasn't manifested in content.opf. Check the original epub with the IDPF validator and post the results here.

Alternatively, if it was an epub3 but had version="2.0" in the OPF package tag, it would be treated like an epub2 and then a toc.ncx would be needed. The OPF package tag version attribute determines how the epub will be treated (as an epub2 or an epub3).

Yes, what does epubcheck return for this epub?

I'm concerned with the statement "text appears with a bunch of tags in Book View." I'm hoping the user is merely confusing Code View with Book View. If the tags are truly appearing in Book View, then the epub in question surely has enormous issues to begin with.

C-novice · 05-03-2018, 09:43 PM

No, it is the Book View here's a sample of how it looks.

'. . .he had always done. 
<!DOCTYPE html>

The validation list is quite long but this this the repeating pattern.

It's no biggie now as we were able to use another document.

KevinH · 05-03-2018, 10:27 PM

Wow, certainly not a valid epub3! What generated it?

No, no...if this is right:

@C-novice...Whenever you get xmlns declaration errors all over the place in your html code, this usually indicates that there is an xmlns attribute declaration missing from within the <html> tag in the headers at the top of your html files.

In Book View you said your ebook text looks like this:

'. . .he had always done. tag at the top of the file:

'. . .he had always done. beyond to the woods. tag line from any epub xhtml file in your next post so we can see it? The <html> tag line occurs directly after the <!DOCTYPE> line in at the top of your html files. As a reference for you, the headers at the top of your epub 3 xhtml files should all start like this:

Spoiler:

You also have a bunch of errors in your opf and toc.ncx file. It would also really help tremendously if you posted the code from the <manifest> section in the content.opf file and also posted the code from the toc.ncx file from your epub into your next post. Your toc.ncx might be using a nav map that uses <navpoint> tags which is only relevant for epub 2 format. For epub 3 you should be using a nav map that uses an ordered list within <nav> tags only. This is another wild guess on my part since I really don't know that much about epub 3 format.

A proper epub 3 toc.ncx looks something like this:

Did you use another application to convert your doc to Epub 3 ? If so, what is the name of the app ? Or did you code your epub manually ?

There no such animal as a proper epub3 toc.ncx. What your spoiler shows is an epub3 navigation document which should show in the text files. nav.xhtml or toc.xhtml seem to be common names but check in content.opf for the nav property to identify the navigation document. Epub3 allows for a toc.ncx for backwards compatibility and Sigil will create a template toc.ncx if the epub3 did not include one or it wasn't identified properly.

Sample navigation document line in content.opf:

Code:

<item id="toc" href="Text/nav.xhtml" media-type="application/xhtml+xml" properties="nav"/>

As for the mess posted by the OP, the last time I saw something like that was when the author copied and pasted from a code view to a book view. On his only bloody copy of the file.

Oh yeah, this toc.ncx looks nothing like your sample. I truncate the list -it's quite long.

The conversion was done with Libre Office. We are a bunch of Sigil novices so since we can't figure out what the dickens is going on, we are ditching both the old .odt and epub file and start over.

If the toc.ncx and manifest I post offer any insight into what we did incorrectly, please do say so we can avoid those errors in future.

Thanks for helping.

Would you mind dreadfully sharing how that ePUB was made? Or anything else you can share? Trying to understand what's happened here.

@C-novice...Since you are a novice with Sigil(and html coding) the best I can suggest is that you start from scratch again using your LibreOffice doc. This method to obtain an epub 3 version of your ebook wont take long, only involves a few steps and does not involve any coding in HTML.

Here's my suggestion:

* Download and install the HTML2Epub Sigil plugin from here. Read the release notes for this plugin!!

* Download and install the ePub3-itizer Sigil plugin from here. Read the release notes for this plugin!!

* If you haven't already done so, download and install the Epubcheck Sigil plugin from here.

* Export your doc from LibreOffce as HTML(Writer) + images into a new folder on your desktop. See the HTML2Epub release notes for more details.

* In Sigil go to Plugins > Input and click on HTML2Epub. This plugin will automatically convert your html doc to full epub 2 format and import it into Sigil.

* After running the plugin, check the epub in Sigil using the FlightCrew or Epubcheck plugin to make sure that you have a valid epub 2 file.

* If everything is OK, then select Plugins > Output > ePub3-itizer and run it. This plugin will convert a valid epub 2 file to valid epub 3 format and save it to your desktop.

* After conversion run Epubcheck on your new epub 3 file to be sure.

Also be aware that the HTML2Epub plugin will remove any blank lines caused by the enter key. So make sure that your headings, text and all spacing(space before, space after etc) in your LO doc have been properly styled using paragraph styles only. Unfortunately, since you cannot code in html, if you spot any formatting errors in your epub 3 file, however trivial, then you will have to go right back to your LO doc to correct it and then run the above process all over again.

I'm also guessing that you probably used the eLAIX extension for LibreOffice to convert your LO doc to epub 3. I tried using it once -- very complicated -- I dumped it after only 5 minutes. I mean what can you say about a LibreOffice add-in that has 35 toolbar buttons? That's even more toolbar buttons than LO has on its default toolbars!!..

Oh nothing complexed, just Export As> Epub 3.0 > Split at: Heading.

When we first encounter the issue, we took the epub doc to Calibre and it opened okay there. But we did a convert from epub to epub in Calibre anyway and took it back to Sigil but it was the same. Then we asked you guys for help.

slowsmile, what was the problem? how come our toc.ncx was different from yours and what of the manifest code? What do they tell?

Regardless though,

and everyone on this thread for taking their time to help. This is really kind of you to take the time to write this down for us. We most definitely will try it out with our next LO epub conversion.
