Splitting many large html files

[LoganW]

So I know from the manual and from another thread that you can only split on one html file at a time.

But I have a book with 60+ large files that I'd like to split, and rather than opening each one and right-clicking and splitting on <h2> I would just prefer to automate it. Can that be done with a conversion and XPath somehow? The book is currently in AZW3 format.

Using the calibre ebook editor.

Yes:

What I do is combine all the html files in the ebook into one file, then right click and click split at multiple locations, then use a xpath to do the splits.

If you're referring to splitting using the calibre Editor ... this isn't automated but it's what I do:

1. Use the Merge option to merge all the text files into one huge file.
2. Then use the normal right-click split on <h2> on that file.

That makes sense. And if I wanted to split on both h1 and h2 then do something like the following?

//*[name()='h1' or name()='h2']

You'd need to try it. I'm afraid XPath expressions are not my strong point

I think I've used this one in the past:

//h:h1|//h:h2

Yes that works.

I have also used something like this to match the heading class attribute when chapter heading used a tag other than an h*, e.g. a p tag.

//*[re:test(@class, "chapter|chapter1", "i")]
