Stripping Author/Title and Page Number

taratears · 06-05-2025, 03:55 PM

I'm trying to remove alternating title/author as well as page numbers from the top of the page. (Title|Author) finds some instances of the title, but not all or even most, and doesn't find the author at all. [0-9] removes the numbers I want but also removes all paragraph spacing. Thanks to anyone for the help.

It would help if you posted some examples of the author/title/page number strings.

Is there a consistent class associated with them?

Have you tried using Regex to locate and remove them using calibre's editor (azw3 or ePub books).

Are these books that you are converting?

I can do that, sorry, wasn't sure what info you would need.
I got it in epub format, already.

Red Sky At Morning

 5

4

Melissa Good 

[Red Sky At Morning] [0-9]
[Melissa Good]

Page [0-9]+

(Title|Author)

So far, this is what I've tried. Thank you.

This is exactly how the code appears in the editor (on different lines)

First i would use the main Beautify (tulip icon) to try and get all the files more 'normal' (there can be non-visible differences)
I do these as 2 separate S&R (because they are. The Right page and the Left page in a print book. )

Code:

<p class="calibre3"><i class="calibre1">Red Sky At Morning\s</i>\s*\d+</p>

I included (Guessed) the missing Opening P tag, change it as needed.

I used a s* (zero or more spaces) in some places where it appears a space MIGHT be in some cases

The second (other side) is similar

Code:

<p class="calibre3">\d+\s+<i class="calibre1">Melissa Good</i></p>

If this was code from an OCR, this S&R will almost never get all cases. Each of those will need to be recoded (common error) or hand deleted

My source anna's archive, with no info on if it was ocr, but I'm guessing so. All versions I can find seem to have it. I'll try your suggestions, thank you very much for the help.

Ok, so I'm double checking, are these intended to be just regex or regex + function? I tried created a function, but I'm getting code errors, so maybe its just regex. I'm definitely doing something wrong if thats the case because I'm getting errors, see below:

calibre, version 8.4.0
ERROR: Unhandled exception: error:bad escape \s at position 60

I'd really like to understand because it seems like this could be useful for multiple things, but I'm also struggling with understanding the documentation today. In the manual, I mean. Thank you so much.

??? \s should be valid, but change it to \s*

Red Sky At Morning\s*\s*\d+

The second \s* is because it appears there is a possible leading space befor the single digit.

If that does not work, try the 8.4.101 preview at https://download.calibre-ebook.com/preview/

Hmmm.... sorry but if your source is Anna's Archive, you are not going to get much help on MobileRead. Anna's Archive is a pirate site.
