Calibre doesn't import all of PRC file

[MSJim]

I have a non DRM PRC file that Calibre doesn't appear to fully import. When I convert it to ePub, I'm only seeing about the first 20% of the book. The TOC works, and the text is good until it just suddenly stops. I'm getting less than 6 chapters out of 29. There were no error messages. Converting to RTF also produced a file that stopped at the same point.

I tried the online converters 2EPUB and ePUB BUD with essentially the same results, so I suspect there might be something wrong with the file. However, I can see the full file in Kindle4PC. I don't have any other PRC viewers.

Anyone have any idea what is going on? I'd like to get this in ePub format on my Sony PRS-600.

To start can you view the file in Calibre's ebook viewer?

Try setting a directory in debug prior to converting the file. Calibre will dump to that directory the initial html then it will show you your book at each step.

Viewing the initial html will tell you if the initial step has the whole book, if it does then you can review the css and the html at the point where it stops and see if you can discern the cause.

Good Luck

Thanks for the suggestion. I'll give it a try. I'm very limited when it comes to HTML code though.

I've achieved my original goal of getting the file in ePub format via a very round about method. I tried several converters, and finally got the whole file in a form I could deal with using mobi2html.exe. I then viewed the file with Firefox, copies it to the clipboard, and then pasted it as RTF into Word. I could have skipped the Word step, but I decided to do a little formatting before moving on to Calibre for conversion to ePub.
I suspect there must be a more efficient way to achieve my end goal, but at least this worked.

Although I've got my ePub file, I still intend to troubleshoot the original problem because I'd rather not have to go through the multistep process.

I tried your suggestion. The debug input folder had two html files in it. One, debug-raw.html, has the entire file and is 388k, but the other testfile.html is only 82k and has the text chopped short.

As I said earlier, I'm HTML challenged, but I can't see anything in the HTML code that should cause the file to stop importing. At the point the text stops, the raw file looks just like it does everywhere else to me.

I'm including an attachment with two clips from the HTML files. The first is from the raw file starting at the paragraph before the error, and continuing a couple of paragraphs into the missing text. The second clip starts at the same place in the abbreviated file and continues into part of the error area. It's just a continuous series of </span>'s to the end of the file.

Is there something in the code that I'm missing?

This will be almost certainly because the PRC file contains invalid bytes that are causing the HTML parser in calibre to choke and throw away the content after the invalid bytes.

There's not an awful lot that you can do about it, I'm afraid.

Thanks Kovid. I won't waste any more time on the problem, and hope I don't encounter any more files like this one.

At least I did learn that I have another way to get an HTML file from a PRC input.
