Generated epub file does not display on iBook.

[tassoskoutlas]

Hi,
I generated an epub version of a drupal node through the print module. The epub does not open in iBook and does not validate correctly.

“This page contains the following errors:
error on line 21 at column 27: AttValue: " or ' expected
Below is a rendering of the page up to the first error.”

A similar issue has been filed with the drupal issue queue https://www.drupal.org/node/2147659 but was closed and the author was redirected here.

Can I get you to send me a sample ePub with this error. It looks like
there's a problem with the framework delivering bad XHTML files. (ePub
doesn't support all aspects of XHTML 1.1)

line 21 at column 27: AttValue: " or ' expected

sounds like there's an attribute in the tag, with missing quotes around
its value. ie.

is illegal in XHTML, and should be

or

Cheers

You can find it here http://speedy.sh/KVySh/Site-Install-An-article-2014-07-09.epub.txt

Line 21 is:

    <meta name="robots" content=noindex, nofollow />          <link

rel='shortcut icon' href='http://bl.dev/misc/favicon.ico'
type='image/x-icon' />

The problem is that content=noindex, nofollow is invalid in XHTML,
actually it should be invalid in all forms of HTML, from 1.0 to 5, as
it's two arguments with no quotes.

The problem is that the equp.html is full of elements that shouldn't be
in an ebook, this is the danger of dynamically building these. For the
most part, most can be excused, but because of all the missing scripts,
you are going to get errors from epubcheck, though the above error is
probably the showstopper in iBooks. And I'll assume Google books won't
parse it either.

Second, RDFa is not a valid epub format.

Changing the first few lines to the supported XHTML 1.1 header:

And fix line 21, by adding the missing quotes, causes ePub check to
check the rest of the file returning the text I've pasted here below. As
you can see, the XHTML is full of extra xml tags, that have not been
correctly declared by a schema, probably because they are a part of the
RDFa schema, but still.
All other files haven't been added, most readers can survive that though.

I had the same issue and it was fixed by adding " around an attribute.

<meta name="robots" content=noindex, nofollow />

Try:
