Ibooks epub 3 error : exactly one 'toc' nav element must be present

Firebrand007 · 12-15-2014, 01:47 PM

Hello,

After much hassle, I have managed to produce an epub that is fully validated by EpubCheck and only one error remains when trying to upload to Itunes Producer.

Can someone save me and point out what I need to correct in the elements below ?
I'm doing a fixed layout EPUB3 document, so it seems I need to provide a nav.xhtml in addition to the classic toc.ncx file.
Itunes Producer gives me an an error in OEBPS/nav.xhtml(6) and says :
exactly one 'toc' nav element must be present"

I have posted below the content of my nav.XHTML , content.OPF and TOC.NCX files. Thanks a million in advance for helping !!

Overall your files seems ok. Just wanted to let you know that EPUB3 is supporting HTML5/CSS3 so the use of xhtml is not necessary, you should use html extension instead.
try changing the id of the nav.xhtml to toc maybe that confuses the validator... other than that I couldn't make out the problem.

If it's possible to upload your epub here it would be help.

@odedta,

It has always been possible to use either file extension, I don't believe it makes a difference one way or another.
http://www.w3schools.com/html/html_xhtml.asp

EPUB of every stripe requires XHTML structure (no permissive parsing like webdesign) and should have the application/xhtml+xml mimetype, but file extensions don't matter much.

@Firebrand007,

I don't see the

Code:

<nav epub:type="toc" id="toc">

section in your nav.xhtml

True, thanks for the insight.

Hi Odedta and Eschwartz,
Thanks for taking the time to answer me with suggestions ! Much appreciated !
(and sorry for the late answer due to the end of year celebrations)

>>try changing the id of the nav.xhtml to toc maybe that confuses the validator...
I had actually tried that already, and got another error - if I remember well, the Validator then told me that my nav must "supply a landmarks".

Before getting Eschwartz's answer, I rebuilt all my files from scratch, using a template from a commercially released epub, and this time it worked well.
I'm pretty sure Eschwartz was right (>>I don't see <nav epub:type="toc" id="toc"> in your nav file ), this line is just what was missing and needed.
Those error messages are way too cryptic

thanks again !

Hey, just as long as you got the book to work.

And funnily enough, I was offline too.

Christmas break, you see.
You may ask (well, other people anyway) why does my Jewish school give off for Christmas?

Answer: The high school teachers get off then anyway, why not have that coincide with Winter Break.
Heehee this one never fails to crack me up.

If it's for iBooks, it's NOT ePub 3. It's some bastardized version.

odedta Addict Posts: 398 Karma: 96448 Join Date: Dec 2013 Device: iPad	Overall your files seems ok. Just wanted to let you know that EPUB3 is supporting HTML5/CSS3 so the use of xhtml is not necessary, you should use html extension instead. try changing the id of the nav.xhtml to toc maybe that confuses the validator... other than that I couldn't make out the problem. If it's possible to upload your epub here it would be help.

Firebrand007 Junior Member Posts: 7 Karma: 10 Join Date: Jun 2011 Device: Ipad	Hi Odedta and Eschwartz, Thanks for taking the time to answer me with suggestions ! Much appreciated ! (and sorry for the late answer due to the end of year celebrations) >>try changing the id of the nav.xhtml to toc maybe that confuses the validator... I had actually tried that already, and got another error - if I remember well, the Validator then told me that my nav must "supply a landmarks". Before getting Eschwartz's answer, I rebuilt all my files from scratch, using a template from a commercially released epub, and this time it worked well. I'm pretty sure Eschwartz was right (>>I don't see <nav epub:type="toc" id="toc"> in your nav file ), this line is just what was missing and needed. Those error messages are way too cryptic thanks again !

And funnily enough, I was offline too. Christmas break, you see. You may ask (well, other people anyway) why does my Jewish school give off for Christmas? Answer: The high school teachers get off then anyway, why not have that coincide with Winter Break. Heehee this one never fails to crack me up.
