Error epubcheck

[DiapDealer]

Add xmlns:opf="http://www.idpf.org/2007/opf" to the opening metadata tag in your OPF file and most of your structural errors ("exists in the zip file but is not declared in the OPF file") go away.

You have:

<metadata xmlns:dc="http://purl.org/dc/elements/1.1/">

Needs to be:

<metadata xmlns:dc="http://purl.org/dc/elements/1.1/" xmlns:opf="http://www.idpf.org/2007/opf">

That being missing affects all the "opf:(role|scheme)" properties in your dc:metadata (of which the unique-identifier property is a very, very important one).

Also your dc:identifier tag is malformed. You've got an extraneous closing tag in it.

<dc:identifier opf:scheme="ISBN" id="bookid">urn:isbn: 978-2-917088-37-1> </dc:identifier>

Get rid of the stuff in red and the only errors that remain are html syntax.

A <span> must be part of one of the elements described. It cannot exist out of its own. This is wrong:

<p>Paragraph one</p>
<span>A span on the loose</span>
<p>Paragraph one</p>

This is correct:

<p>Paragraph one</p>
<p><span>A span on the loose</span></p>
<p>Paragraph one</p>

or even:

<p>Paragraph one</p>
<div><span>A span on the loose</span></div>
<p>Paragraph one</p>

Otherwise you need to post an example of your file before we can say anything useful.

Thanks for all your advises. Unfortunately it doesn't work within the <span> between 2 <p> sections, and adding xmlnspf="http://www.idpf.org/2007/opf" doesn't work neither. It is mysterious... I'll let you know, trying again and again...

But it does work. It's not mysterious at all. The file you provided had all its structural errors fixed with the changes I indicated.

[Toxaris]

What does not work? Does the code not do what you want or do you still get errors? If the first, please tell us what you want to achieve. If the latter, please post an example of the error and the code. A full HTML would be the best for spotting the problem.

The OP provided a link to an error-prone epub in post #12.

[Toxaris]

Yes, but his adaptations did not work so we need to see what he did and did not adapt of course.

Hi Buble
I have found some more error in your epub file:
1) Attribute should be quotes.
2) Width should not be defined in xhtml file for the image. it may in css.
I have corrected and upload your file.

[Buble]

(Sorry for the late answer, out of office)
You're right, it does work !! Sorry... It is really great, thank you SO MUCH !! I note it for the future ^^

[Buble]

I replied before seeing the page3...
Hi Jesver, I can't believe how kind it is, thank you so much !! And of course your epub works perfectly. I still have a few things to do on it (I have to form a new toc.ncx because I want my epub to open each chapter on a new "page") but everything is gonna be alright now. Thank you agaian, all, for your advices, very precious to me !! I learn more and more everyday and it is important to me not to give up.

Hi
Now I understood my previous errors ! But I have one more question : I wanted to divide my chapters in many files in order to force the reader to start each chapter on a new "page". So in a first time I tried with just one new "chapter" : I tried to put on a separate file the title-page from the rest of the book. My epub was without errors (checked with epubvalidator) and suddenly it tells me that I have html errors in my file which were good before... Do you follow me ? What happened ? I just moved away a part of the book by creating a new file appropriate to it (with the same head...). If you would like to have an idea, check on that : thanks for your advices

The 1.epub is the the original, and the 2.epub is the one I tried to put on separate files... thanks for your advices

Calibres editor includes a split tool which make splits painless.
In the Live preview Use the paper airplane like button, move the green line to the desired split point: Click the mouse. in seconds is is done with all the needed 'adjustments' also done. (repeat for each desired split point) Save. Done.

Hi
What can I do if the error "not declared in opf" is still here whereas I have changed my metadata line in the opf ?

You need to stop trying to do things manually and let an editor do the nitty-gritty details for you. You seem to be flailing around and you don't need to be.

Or if you want to continue doing things "by hand," you're going to need to attach the epub. Without seeing the all the code, no one can possibly guess what might be wrong (other than the new split file ACTUALLY not being declared in the opf file, of course).

[Buble]

Ok, sure, here is my file :

I would love not to do it "by hand" but I don't know how to do it in an other way : "my" Calibre doesn't purposes me to edit the books (it just makes the conversion), and I did mine with word (conversion to html) and then RJ textedit where I put the css in an other file, and create the content.opf and the toc.ncx... But if you know a software or have a better solution, of course I take it !
Thanks for your support.
