Page Numbers

Quietmouse · 06-11-2011, 10:16 AM

Hello,

I am new to Calibre and also to regex expressions and I am struggling a bit with what seems like should be a very simple problem.

I have a PDF file which I have converted to MOBI format with Calibre, and I am trying to remove the page numbers as they crop up in the middle of the text. I have used the expression \d+</p><p class="calibre_8"> which the test function of the wizard recognises, and highlights all of the items I want to remove correctly.

(267 occurances, all of which are page numbers with a paragraph break immediately after them.)

However when I actually convert the file, it doesn't remove the page numbers and I don't understand why.

Can someone explain to me what I am doing wrong please?

Thank you

(I have searched for previous forum posts but can't find anything similar?)

The fact that you have "calibre_8" in your expression indicates something odd is going on - you shouldn't see that for pdf input.

At a guess, you need to support spaces between the closing and opening paragraph tags:

Code:

\d+</p>\s*<p class="calibre_8">

But you might be better off converting from the original pdf file...

Thank you, I'll try that

Having gone back and looked at it again, I think what I was doing was trying to remove the page numbers after the conversion to MOBI.

I did try that expression above with no success, but I then started again from scratch and managed to get it to work straight away using \d+<b> on the PDF, so a case of me being an idiot I think.

Thank you again,
