EPub works in Amazon KDP but not in Google Play

Lafisrap · 04-05-2021, 11:05 AM

Code:

Error while parsing file: attribute "class" not allowed here; expected attribute "dir", "lang", "version" or "xml:lang"

I like to publish an ebook created by ebook-convert 4.23.0 on Google PlayStore and their epub validator returns

Code:

Error while parsing file: attribute "class" not allowed here; expected attribute "dir", "lang", "version" or "xml:lang".

for every chapter. I found out removing class attribute from the html tag solves the problem.

Code:

<html xmlns="http://www.w3.org/1999/xhtml" class="calibre">

I also read here: https://bugs.launchpad.net/calibre/+bug/1897582 , that it might be a css attribute assigned to the html element.

But I don't find any style information, that I set on the html element. I just pass in a markdown file with additional CSS set, but this contains nothing for the html tag. And if I omit it, I get the same error.

Is is possible to tell ebook-convert not to add the class somehow?

Here is the command I use:

Code:

ebook-convert /tmp/ebookmaker_tmpfile.epub.md path/to/book.epub --language "de" --title "Booktitle" --authors "Author" --output-profile "kindle" --book-producer "ewer" --comments "MIT" --isbn "9798683069964" --pubdate "<DATE>" --publisher "Michael Schmidt" --extra-css "[path to]/media/global.css" --embed-all-fonts --line-height "22" --change-justification "justify" --formatting-type "markdown" --toc-title "Inhalt" --level1-toc "//h:h2" --use-auto-toc

Any hints appreciated ...
