Regex: How to remove underscore from words beginning with

Question

I need help with Regex to find all words beginning with Denti and remove underscores.

Example:

Denti_Cal_Project_Status

Required Output:

DentiCalProjectStatus

I could use Notepad++.

Answer 1

Anchor the matches to Denti by use of the \G anchor.

(?:\G(?!^)|\bDenti)[^\W_]*\K_

See demo and explanation at regex101

• \G(?!^) chains matches to a previous match
• \K resets beginning of the reported match
• [^\W_] is a short for [A-Za-z0-9]

Replace with empty string.
