Possible to use <title> tags as TOC headings?

playful · 07-11-2020, 10:47 AM

Hi there,

A bit of a Sigil-noobie question.

Working with 1000+ html files.
Each has a proper title tag such as <title>1 - it all began here</title> but no h1, h2 etc. tags.

Out of the box, when generating the TOC, is there a way to make Sigil take the <title> tags into account?

As a workaround, I've added some <h1> tags to the 1000+ pages with a simple regex-replace, but that's not really my first choice.

Thanks!

p.s.
For reference if someone on the same track needs that workaround:
Search: (?s)(<title>([^<]+).*?<body>)
Replace: \1\n<h1>\2</h1>\n

The title tags would normally have the book's title and not the chapter title.

Alright, let me explain. I'm converting a website to an ebook. The website has 1000+ pages. It's standard for the html pages of websites to each have their own <title> tag.

Looking at toc.ncx, I can easily generate that in Python.
After generating the <h1> tags as mentioned above, now that I have the TOC, I can easily strip the <h1> tags again.

Just wondering if there is a way to do it out of the box, for future reference.

Thanks!

No, I don't think Sigil has a built-in function for that. However, you can save that regex and easily have access to it in the future (under Tools/Saved Searches).

As for the regex in your example. It is more complex than my reg-fu can easily decipher...I have some homework to do!

No out of the box functionality like that, no.

If you know python, you could probably do a quick plugin to build an ncx from title tag values. Or you could have it insert nodisplay h tags into the top of all html files with the title tag values added as content (or title attributes) with your above regexp. The latter would allow you to use Sigil's built-in ncx generator.

@Turtle91, @DiapDealer,

Thank you for the great ideas! (saving the search, the no-display h tags…)

Solved!

You could do this with 2 Find/Replaces. One to insert the <title> as <h1>, and one to remove the <h1>.

Note: Make sure you turn Sigil into Regex mode, and make sure you check the box for Dot All.

Step 1: Convert <title> into an <h1>:

Find: <title>(.+?)</title>(.+)<body>
Replace: <title>\1</title>\2<body><h1>\1</h1>

Step 2: Press Tools > Table of Contents > Generate Table of Contents, then create your TOC.

Step 3: Do the opposite. Remove the <h1> we just created:

Find: <body><h1>(.+?)</h1>
Replace: <body>

If you do this often, you can even create a Saved Search for both of those fixes.

No. For more extensive discussion on best practices for <title>, see discussion in the 2018 thread "Two questions", especially my Post #2.

Hey there, it looks to me that you missed this entire part of my original post:
