Epub validator error code assistance

LGDesign · 03-03-2013, 12:11 AM

Used InDesign CS5.5 to create an ebook as I have done previously. However while past books have been validated, the current book is getting the following error code.

Error code:
Irregular DOCTYPE: found '-//W3C//DTD XHTML 1.1 //EN', expecting '<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.1//EN" "http://www.w3.org/TR/xhtml11/DTD/xhtml11.dtd">'.

Any help regarding what this means and how to fix it would be greatly appreciated. Thank you.

Some page in your ebook has

Code:

-//W3C//DTD XHTML 1.1 //EN

while the correct DOCTYPE (for EPUB 2) is

Code:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.1//EN" "http://www.w3.org/TR/xhtml11/DTD/xhtml11.dtd">

Sigil doesn't work on my operating system OSX10.6.8. Any recommendations of how I can alter the CSS or other software to try?

I am wondering why this is occuring now with my files when it hadn't previously. Is it because of EPUB2 & 3?

Many thanks in advance for any advice. I don't create ebooks enough to stay on top of all the new developments.

Unzip the ebook and then edit it using any text editor of your choice.

It is hard to tell, without seeing the code.
