Forma kepub rendering issue ( i know its a case of GIGO, but...)

[stumped]

so i have a poor quality text with many embedded spans, mid paragraph, like this:
part of paragraph text <span aria-label="page 17" epub:type="pagebreak" id="page_17" role="doc-pagebreak"></span> remainder of paragraph text

in calibre editor, sigil book view, ADE... they are harmless i.e. invisible.

so in fact i never noticed them until I began to read on Forma , and wondered why I was seeing so many "wrong", often mid sentence, paragraph breaks


it seems that on my forma, i get unwanted line breaks whenever such a span is encountered. i.e. the span is interpreted as a <br> , but is otherwise ignored

i am seeing this in a sideload from calibre, so dunno if its the extended driver , building kepub on the fly, that is struggling, or if it would also happen with a proper kepub source. [ the on-the-fly kepub conversion is not retained in calibre , I would have to look up how to capture a copy, in order to dig deeper

I do recall a similar thread ( but cannot find it now) where similar poor coding but with embedded anchors was causing a font size change on kobo.

i can, and did regex it all away, but what should a renderer do with such junk. Why is it NOT a problem on PC, but becomes a mess on Kobo.

is it the epub:type="pagebreak that is doing the damage, or would an embeeded span withonly a page_ID bit also mess up

Possibly related to extra <br/> issue in the current KePub plugin version (c.f., the relevant thread, @davidfor has posted a patched version).

Interesting, thanks. Was not aware of a big that added line breaks.
Was thinking I would need to build a series of test files with different degrees of GiGo span and anchor junk, and see at what point the test files started to bug out

My plugins do update automatically. But maybe that patch is not in a full release yet?

Are we talking about the same plug in?. The one I use is the extended driver that converts epub to kepub as it copies files from calibre to kobo

I went and read the relevent thread. I think mine is a different issue. There are no <br> in my junk spans. So it's something ese that is causing the paragraphs to split at span points

The <br/> was one issue that was noticed. Perhaps you are getting a similar issue. It might be worth checking your epub vs. the generated kepub to see if you have the added </p>....<p> pairs. Or convert the epub to kepub using kepubify and see if the problem persists.
