Classic Nook crashes with epub from html with arrows.

Archon · 01-29-2011, 08:45 AM

I have installed some epubs that I converted from html with Calibre to epub.

The HTML version has a TOC page with chapter links and arrows at the beginning of each chapter to take you to the TOC or back and forth between chapters.

If I load the book as-is onto my new Nook it can't open the file and fails back to the menu.

If I remove all the navigation links from the epub then the nook takes it just fine.

This tag apparently crashes the Nook.
<div class="right"> <A HREF="#contents" class="nava">&#94</A> <A HREF="#chapter_2" class="nava">»</A></div><div>

This tag from a different book apparently does NOT crash the Nook.
<p class="sgc-5"><a href="#contents"><img alt="Top" border="0" src="../Images/Top.gif" title="Top" /></a> <a href="#chapter_2"><img alt="Next" border="0" src="../Images/Next.gif" title="Next" /></a></p>

Thanks for your input

I notice three odd things with the first one. They may or may not be related to your problem.

There is one div tag but two /div tags.
There is an ampersand that doesn't introduce an entity (&#94 probably should have a semicolon after it).
There are tags and attributes in upper case. EPUB is based on XHTML, which is case-sensitive and has all standard tags and attributes in lower case.

Thanks I will keep a look out for those things in other files.

I agree with what Doug says, especially the missing semicolon.

One thing - there actually are 2 <div> statements and one </div>. The final <div> may be the start of the next div, so you might not want to fool with that.

Thanks it seems the other files I have with nav arrows work just fine apparently somebody used a poor structure or non-standard structure on this file.

I was just curious what would do that to the Nook.

My solution was to delete all the HTML links in the file and it worked fine after that.

Thanks for your analyses kind people.
