Since this simple regex will find title case strings everywhere, you can't use it with Replace All, though.

To replace two consecutive title case words use the following regex:

Find: ([[:upper:]]{1,})([[:lower:]]+) ([[:upper:]]{1,})([[:lower:]]+)
Replace: \1<small>\U\2\E</small> \3<small>\U\4\E</small>

Thank you sir. I will give it a try.

here's another version using a look behind.

find:
(?<=[A-Z])([a-z]+)

replace:
<small>\U\1\E</small>

One of the things I spend the most time editing is bad paragraph breaks. For instance, Tom continued his paragraph

on another line.

The easiest way so far is to regex Search:

</span></p>

<p class="calibre9"><span class="calibre6">[a-z]

then manually <shift> arrow left, and hit space. I would love to Search for the paragraph starting with a lowercase letter, but leave the letter intact and Replace everything before it with the space so that I can replace all at once.

Any help would be greatly appreciated.

You were almost there

(?sm)</span></p>\s+<p class="calibre9"><span class="calibre6">([a-z])

(a space here)\1

the slash 1 puts back the captured letter from above

That is awesome. Many more uses for the \1 now. Thanks a bunch.

\1 is only the notation for 1st capture
just like \9 would be the 9th capture (never been past \4 myself )

It is the search term that is the magic

Get a REGEX Cheatsheet and keep it handy.

Did I overlook a Regex that forces uppercase after period, exclamation mark, interrogation mark and white space, in the case of initial quotation mark without white space?

Thanks in advance!

[Leonatus]

Well, I checked it out by myself and found that [.\!?] [a-z] will find any lowercase after punctuation marks, with or without whitespace.

[\.\!?] [a-z]

If you are looking for a period, you need to escape it or it becomes a wildcard

finds:with 0 or one space (but not a nbsp)

\s?[\.\!?][a-z](\s)?

[DiapDealer]

Consider replacing [a-z] with \p{Ll}

That way, lower case unicode characters can be matched as well. You never know when a random "é" or "á" will bite you in the butt (and not just in the above regex).

[a-zA-Z] becomes \p{L}
[a-z] becomes \p{Ll}
[A-Z] becomes \p{Lu}

[Leonatus]

Ah, thanks!
Somewhere I had read that inside square brackets some marks don't need to be escaped - except "!". However, I'm through the text, but I shall try again with the escaped period - maybe there were no matches with period and I didn't notice it.

The major problem had been in the "replace" sector: I had to replace everything manually, because all of my ideas concerning regex were inserted literally (no success)

@DiapDealer: {Ll}: I don't understand neither the meaning of "L" or of the pipe. Which is their general function?

That's actually a lowercase "L" rather than a pipe.

\p{L} matches any letter character in any language
\p{Ll} matches any lowercase letter character in any language
\p{Lu} matches any uppercase letter character in any language

Even books in English use accented characters that will be overlooked by [a-z].

NOTE: the L or the Ll or the Lu have no special regex meaning outside of the \p{} construct. They simply represent unicode properties/categories. \p{} matches a single character belonging to the specified category, and \P{} matches a single character NOT belonging to the specified category.

Thank you!

I just see that lowercase letters after period have been matched, even without escaping the period.

What I further do not understand is, why my command didn't care about space between punctuation mark and letter, i. e. there was a match with and without whitespace.

I am looking to do some mass-renumbering of ID's in a book in order to insert endnote hyperlinks.

What I want to do is transform something like:

"id012345" .... "id012444"
to
"ref_1" .... "ref_100"

Significant here is that the last digit of the transformed number is not the same as that of the original. (It would actually be the footnote number extracted from the main text where it appears as [1] ... [100] )

Has anyone found a way to do this with Sigil's regex ?

[Doitsu]

You can search for the footnote number with \[(\d+)\] and the footnote id with id(\d+) and then combine both.
