Editor: conversion to lowercase with regex

Sam Sahara · 05-13-2018, 05:36 AM

Hallo.

Can you suggest a regex to convert a group of uppercase letters to the same letters but lowercase?

Let say I have the following strings:

Code:

I. GROUP ONE
II. GROUP TWO
III. GROUP THREE
IV. GROUP FOUR

I'm looking for a regex to convert in the following way:

Code:

I. Group one
II. Group two
III. Group three
IV. Group four

---------

EDIT
I tried the following:

search

Code:

(.*?)\. ([A-Z])([A-Z ]*)

replace

Code:

\1. \u\2\L\3\E

but calibre gives: "error:incomplete escape \u at position xx"

You can do that with one of the Regex functions. The search should be:

Code:

[IVX]+\. (.*?<)

That assumes the lines are wrapped in a tag.

Then select "Regex-funtion" as the mode and "Title-case text" as the function.
