Regex replace p-class in entire book

AlwaysNew · 07-02-2020, 08:11 AM

Hi, I'm new at this so bear with me.

Trying to replace this...

Code:

 <p class="p23">[keep everything inside here]</p>

with this...

Code:

 <h1 class=“p15”>[keep everything inside here]</h1>

throughout all chapters in book.

I've tried Diaps Plugin but it's a bit beyond me. Any help sincerely appreciated!
Thanks.

Search for...

Code:

<p class="p23">(.*)</p>

Replace with...

Code:

<h1 class="p15">\1</h1>

Thanks JS, but the replace code you suggested replaces the entire chapter.

I need to replace one open and closed p tag (with a nested span and chapter title inside it) with an h1 tag.

That is, from this:

Code:

 <p class="p23"><span id="chapter-5"></span>Coming Home</p>

To this:

Code:

 <h1 class="p15"><span id="chapter-5"></span>Coming Home</p>

And I want to do that with every succeeding chapter in the book.

Thanks in advance for your help!

This will do:

Search:

Code:

<p class="p23">(.*?)</p>

Replace:

Code:

<h1 class="p15">\1</h1>

IMHO it's well worthwhile to learn Diaps PI -- I use it all the time and it's a lot easier that debugging some complicated RegEx

It's configurable so you can add additional tags

This does what you asked, but it you want to key off of the id="chapter.." it's a little more complicated

Result is

Code:

<h1 class="p15"><span id="chapter-5"></span>Coming Home</h1>

Thanks Phossler. That screenshot is helpful. I will try get my head around it. In general, the object here is to clean up Calibre's code from an imported Pages epub so I end up with a lean mobi for Kindle :-)

This is very useful page, I have it downloaded to my PC and the bookmark points to the local saved page.

OK, I've tried using the regex as recommended, but now it's messing things up.

When I search this:

Code:

 <p class="p32">(.*?)</p>

And replace it with this:

Code:

 <h1 class="p20">(\1)</h1>

It changes this:

Code:

 <p class="p32"><span id="chapter-5"></span>Coming Home</p>

To this:

Code:

 <h1 class="p20">(<span id="chapter-5"></span>Coming Home)</h1>

That's just one chapter example, but it puts parentheses around all the chapter titles. What am I missing here??

Any help truly appreciated as regex is not easy for me.

In the replace, you do not need the round brackets. That is why the changed version shows brackets. You asked it to add them.

theducks · 07-09-2020, 04:43 AM

Replace NEVER gets the (search) Capture Paren
\1 is the value that will be inserted
When you included the LITERALS ( and ), that is what was ADDED, because that is what you told it to do.

Question, why are we still going over this when @phossler gave the ultimate answer that works?

I appear to be missing something, How do you "configure" the plug-in. There is no option to do so and "Help" says it isn't configurable. Not only that back in the mists of time (2015) DiapDealer said he didn't want the PI to be able to swap tags in this way.

Does this involve some arcane tweaking of a file somewhere ?

I have long tried to use the plug-in to achieve the task of converting a classed "p" tag to a "h" tag and have always had to do it by regex. As I see it the only thing you can change a "p" to is a "div".

I normally just use the parameters screen to add additional tags, but IIRC I did have to one time tweak (VERY carefully) the file:

Code:

C:\Users\......\AppData\Roaming\calibre\plugins\diaps_editing_toolba
g_SpanDivEdit_settings.json

Don't recall exactly why, but I THINK it was because I wanted to modify a tag that wasn't in the original distribution

Been awhile since, once I had everything set, there hasn't been any reason to change

Sorry, my bad. I put (\1) instead of just \1 in the replace field. I'm still learning.
