What's this validation error and how to fix it.
 

I just had an error pop up validating a epub with a mountain load of hyperlinks

I've solved the problem... (turns out there was a "&" in web addresses jumping in everywhere).

Anyway my point is:
It would be great if there were a sticky thread listing error messages which epubcheck throws up and also the solution to the error...

Saves us spending hours looking up solutions to it....
Unless there is already one here, of course...:p


Error:
This refers to the a web address hyperlink at line 43.

Solution
The web address had missing ; after an ampersand, and also ampersands didn't have the correct & in place:

For example, the bold in the code line is what I inserted to make it work:
Fixing this also automatically fixes the "fragment identifier is not defined in" error

xxxxxlve it.

I feel your pain - the cryptic errors messages from epubcheck make it unnecessarily tough to fix the validation problems. There is a list of several error messages on the epubcheck wiki, but it isn't a complete list: http://code.google.com/p/epubcheck/wiki/Errors

Even better than a list of common error messages would be to fix the error messages themselves! Soon I'm hoping to have some time to dig into the epubcheck code and improve some of the error messages.

Try preflight (if you haven't already) http://code.google.com/p/flightcrew/ it gives much more understandable error messages.

It's FlightCrew. :)

I'm adding this to the list of FlightCrew misspellings I've seen. The list so far:

• FlightControl
• FlightCabin
• CabinCrew
• AirCrew
• EpubCrew
• FlightCommand
• preflight

:D

haha beers at the office, yes flight crew is the way to go for understandable epub errors

epub errors
 

hi!

i'm a newbie to this. anyways, i just ran epub check on my .epub file and it gave me a lot of these errors.
does anybody know what this means or what i need to modify for this?

file.epub/toc.ncx(150): 'Toc237708557': referenced resource missing in the package

thanks much!

Just what it says :D (because it looks like malformed garbage crept in)
something is referencing toc237...
Notice No extension.
the number part , may have been a fragment of a (now mangled) file name, hence the "not included in the (epub) package .

:bulb2: Please don't keep posting new messages on the same subject;
you may have to wait time for someone to come along and reply.
The continue the same thread until resolved.:thumbsup:

Just trying FlightCrew now - very handy. I've fixed most errors, down to the last three. Strangely, only two errors appearsing on three press' epub-validate and they appear to be different issues! A new world of confusion :)

Can anyone tell me if these FlightCrew error messages are worth worrying about:

1. The <reference> element's "type" attribute has value "title" which is not an OPF-specified value. Either use a predefined type or start your type with "other.".

2. The <reference> element's "type" attribute has value "content" which is not an OPF-specified value. Either use a predefined type or start your type with "other.".

3. The <reference> element's "type" attribute has value "title" which is not an OPF-specified value. Either use a predefined type or start your type with "other.".

As none of them appear as errors via Three Press. I'm new to this and it is quite confusing.
