Is there a viewer or plugin of any kind that would allow an .epub document to be viewable on a web page? A Google search turned up tons of installable epub viewing desktop software but I couldn't seem to find anything for embedding this format on a web page. Perhaps you folks have some insight into this?
epub files are just HTML/XML and CSS, so you could easily open the epub container (it's a zip), then parse the XML inside using a language like PHP.
It shouldn't be too difficult to do that.
The format looks like:
--ZIP Container--
mimetype
META-INF/
container.xml
OPS/
book.opf
chapter1.xhtml
ch1-pic.png
css/
style.css
myfont.otf
Here's an example of the content you might find in chapter1:
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.1//EN" "http://www.w3.org/TR/xhtml11/DTD/xhtml11.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en">
<head>
<meta http-equiv="Content-Type" content="application/xhtml+xml; charset=utf-8" />
<title>Pride and Prejudice</title>
<link rel="stylesheet" href="css/main.css" type="text/css" />
</head>
<body>
...
</body>
</html>
