Inspect ePub on KOReader

bunglegrind · 12-22-2021, 01:52 AM

Hi,
I need to inspect the DOM of some epubs since there are issues in viewing them within KOReader which I cannot reproduce in other viewers that have an inspector (specifically, calibre viewer).

Is it possible?

(I'm using KOReader in Kobo Aura One)

Cheers

Maybe highlighting the text and "View HTML" cah help somehow?

Another alternative is to use ScrambleEbook to share it (while of course being a little more specific about what kinds of issues; it might not even be necessary to share anything at all in that case

).

No, it's not enough. In order to detect errors in my epubs (which I generated from HTML pages) I need more...

Have you checked the ePub with epubcheck?

Also, it may not be an error in the ePub but a rendering error with KOReader.

Nice tool, it looks for malformed epubs. But I'm concerned of wrong css attributes in well formed epubs. Anyway, thanks for your reply.

The best way to understand and demonstrate a problem is to write a minimal testcase.

Code:

<!DOCTYPE html>
<html>
<head>
<title>issue</title>
<style>
#issue {
 color: green;
}
</style>
</head>
<body>
<p id="issue">This demonstrates the issue. It should be green but it's red!</p>
</body>
</html>

In lieu of that, refer to what I wrote previously.

Well, there is some misunderstanding...I was only looking for a tool to inspect the DOM generated by CREngine in KOReader. And it doesn't exist.

Of course, whenever I submit an issue, I write a test case to help developers to understand what is happening, but this is another matter.

Anyway, thanks for your help!

What do you mean by doesn't exist? As @hius07 said, highlight the text and select "view HTML" to see the DOM as interpreted by crengine.

but it's not a DOM inspector. It shows you a "static" view of HTML and CSS files. A DOM inspector shows you for each node which styles are applied,from which rule, what are their computed values, etc.
