To separate an EPUB file to multiple file, I need to find all <h2 and replace them with <hr class="sigil_split_marker" /><h2. However, each element of a chapter is consisted in its own html file, which means I can only replace once at a time. And when splitting it, it gives the error:
Cannot split since at least one file may not be an HTML file.
Q: How to split the file into multiple files, each consists the opening image, chapter name and its contain?
Below is the structure of the file:
Head
Every page has the same head.
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<title>Packing for Mars</title>
<meta content="http://www.w3.org/1999/xhtml; charset=utf-8" http-equiv="Content-Type"/>
<link href="../Styles/stylesheet.css" type="text/css" rel="stylesheet"/>
<style type="text/css">
@page { margin-bottom: 5.000000pt; margin-top: 5.000000pt; }</style>
</head>
