Hi, folks. I'm working on some code for a client which crates EPUB 3 files. The books are working fine in iBooks and Calibre, but now we're trying to upload the file to Google's book store and getting stuck with the lingering error:
"EPUB/toc.xhtml:2, 203: Error while parsing file 'Exactly one 'toc' nav element must be present'."
But there is most definitely exactly one 'toc' nav element in the TOC file, and it matches the spec in other ways as well, as far as I can tell. I presume there's
something different that I'm just not seeing, even after comparing this TOC file with a few others from other EPUB files, but I still can't see it and I'm about to start flipping tables.
Maybe it just needs to be seen with a fresh pair of eyes, so if someone could have a quick look at this and see if they can spot something wrong, I'd greatly appreciate it. It's quite long, but I presume the error lies somewhere near the beginning.
(The code below has been run through "xmllint --format" to make it more readable; the "real" file is a bit messier. But that shouldn't make a difference, right?)
Code:
