How do you embed an .epub in a web page?

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?

Solution

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>
