EDIT: It was some issue with Notepad++'s regex engine. The regex worked fine in Python.
I'm working in Notepad++. I tried to make a regexp that would transform this (if you're curious, it's a Spanish guide for a game):
*Acero: En la Estatua de Gabomba
**Absorbe PV de un enemigo
To this:
====Acero====
*En la Estatua de Gabomba
*Absorbe PV de un enemigo
I came up with this, but it doesn't match the text:
\*([^:]+): ([\w ]+)\n\*\*([^\n]+)
Am I missing something obvious?
It seems that Notepad++ cannot find line breaks in regex mode. You'll have to replace the line breaks with, say, |, in extended mode, apply the regex on your new string, then replace the |s with line breaks.
Your regex is correct. Try to search for \*([^:]+): ([\w ]+) and \*\*([^\n]+) separately and it will match.
It is just that Notepad++ does not support multiline regular expressions (because Scintilla doesn't). Note that there are two different search dialogs available: Ctrl+F shows the builtin dialog, Ctrl+R shows TextFX's dialog which has more options. But TextFX doesn't support multiline search either.
