need help to create a regex

Dr.Strangelove · 05-06-2023, 06:59 AM

I have an epub which has tags like this in html

Code:

 <body id="CCNA0-13649bfe67614ed3be03405aa6e1ffaf" class="calibre">

and this in toc.ncx

Code:

<content src="text/part0011.html#AFM60-13649bfe67614ed3be03405aa6e1ffaf"/>

For the first line, I need to replace it with

Code:

<body class="calibre">

whatever the id is.

For the second my idea is to replace

Code:

html#AFM60-13649bfe67614ed3be03405aa6e1ffaf"

against

Code:

html"

- again whatever the long id is.Could somebody help me with the regex? I am not able to find a way using wildcards for the id

Try...

find: <body id=".*?" class="calibre">
replace: <body class="calibre">

find: html#.*?"
replace: html"

I'd tweak it slightly with a much more narrow:

Find: <body id="[^"]+" class="calibre">
Replace: <body class="calibre">

Find: html#[^"]+"/>
Replace: html"/>

Those 2 regexes are kind of saying:

"Hey! Keep going as long as you're NOT a quotation mark!"

It's a little bit safer than .*?, which can sometimes go crazy if you weren't expecting it.

@Karellen
The first one works like a charm. I needed to change the second one to

Code:

html#.*"

otherwise it includes too much.

Thank you!
