Replacing text in Sigil

Davvy123 · 09-30-2018, 02:17 AM

Hi, I'm new to Sigil, and just joined Mobileread in order to get some help with editing ebooks and learning how to use Sigil effectively.

My first question is how to use Regular Expressions to edit out or find/replace certain text in an epub. I have seen a Regex tutorial here on these forums, but I'm not very technical, and got lost pretty quickly reading through it. So I'd like to ask if you can help me with an actual problem, once I learn the solution, I think I can work my way back and figure out how to solve my next one on my own.

For example, I have an epub with the following lines:

Hob_0375758275_3p_fm1_r1.qxd 8/30/01 9:35 AM Page iv
Hob_0375758275_3p_fm1_r1.qxd 8/30/01 9:35 AM Page a

There are many other lines like that sprinkled throughout the pub, over several .html pages. Each line has the "Hob_0375758275_3p_fm1_r1.qxd 8/30/01 9:35 AM" string repeated, as well as the tag . And then within the tag there are page numbers, as shown in the above examples, and these change from instance to instance.

I'd like to just get rid of all of these lines of codes. How would I do this? Do I have to work on each .html page, one by one, or can I actually do a bulk find/replace that would span all .html pages and get rid of these lines?

Thanks in advance for your help!

Find: Hob_0375758275_3p_fm1_r1.qxd 8/30/01 9:35 AM Page (.*?)
Replace: (nothing)

The "(.*?)" is like a wildcard for the page numbers: the "." means any single symbol; the "*" means "zero or more times"....so that will find any batch of symbols no matter how long. The "?" means not to be greedy...meaning it will only select the characters before the first "" it finds...not all the way until the last ""at the end of the document. The "()" around it just tells it to remember the symbols that it finds so we can do something with them later using the code \1 (or \2 or \3 etc depending on how many groups you've saved).

In this instance you don't really need them because you are just going to delete them, but if you wanted to do something similar you could replace the page number into it's own paragraph like this:

replace: Page # \1

From your example that would give us:
Page # iv
Page # a

Cheers,

edit: to replace all of them in the whole epub with one button push just make sure you have "All HTML Files" selected at the bottom, not "Current File" and then push the "Replace All" button on the right.
WARNING: The "replace all" button is not reversable so make sure you have saved a backup.

I have seen the time increment, so I use:
Find: Hob_0375758275_3p_fm1_r1.qxd 8/30/01 \d:\d\d \wM Page (.*?)

OK. Thanks!

I just went off of what the OP said, but you are right, the time would more than likely increment.

Thank you both for your replies, this worked like a charm, I was able to get rid of all instances of that string.

This particular pub is really full of extraneous metadata information sprinkled throughout the text, is formatted haphazardly, with multiple html files that don't seem to have been cut for any logical rhyme or reason, and on and on.

So I will continue working with it in Sigil. Thank you again, I'll be sure to come back and ask for more help if I get stuck again.
