Add h2 tag to chapter heading to make TOC

Ozman · 08-25-2014, 01:57 AM

I have some old epubs without a TOC that have chapter headings marked as <p>. Each book has approximately 30 chapters, Chapter 1...Chapter 30. It is a drag to manually find each heading, add the h2 tag, and then generate a TOC. I would like to find a way of automating this process.
I tried using calibre to convert epub to epub with heuristic processing to add the tag but nothing happened.
Can I do a find and replace, maybe with regex, to achieve the desired result?

Try this:

Find:<p>Chapter (.+?)</p>
Replace:<h2>Chapter \1<\h2>

Do this one at a time to make sure you don't pick up references to Chapter x in the text itself.

If your chapters are just numbers this Find would be a little safer
<p>Chapter (\d+?)</p>

Many thanks for the replies. I will try out the suggestions. Also, I noticed that some of the epubs are in the form of Chapter One... Chapter Thirty. Grrrrr.

My regex would still work for those, but as I said, do it find/replace, find/replace instead of replace all. It won't take more than a couple of minutes even for 30 chapters. Just match the Chapter case sensitive.
