How to create a navigation file like navigation.xhtml for an EPUB 3.1 book?

A

At least one navigation file, like navigation.xhtml, is required for an EPUB 3.1 book in the book ZIP container. It provides navigation information like a table of contents of the book.

Here is the requirement on a navigation file:

1. A navigation file must be named with .xhtml file extension.

2. A navigation file must be an XML file and meet the XHTML specifications.

3. A navigation file must specify at least 1 "nav" XHTML element like <nav epub:type="toc">, which must have an "ol" sub-element to provide a list of navigation links.

4. A navigation file can be placed in any directory of the EPUB 3.0 book ZIP container. But its exact location must be specified correctly in the package file.

You can create a navigation file with any text editor. Here is an example called navigation.xhtml:

<?xml version="1.0" encoding="utf-8"?>
<!-- navigation.xhtml
  Copyright (c) FYIcenter.com 
-->
<html xmlns="http://www.w3.org/1999/xhtml" 
  xmlns:epub="http://www.idpf.org/2007/ops">
  <head>
    <title>TOC</title>
  </head>
  <body>
    <nav epub:type="toc">
      <ol>
        <li>
          <a href="content.xhtml">Hello</a>
        </li>
      </ol>
    </nav>
  </body>
</html>

Download Hello-3.0.epub, and unzip it. You see an example of "navigation.xhtml" in the root directory.
