@Neculai-I.-Fantanaru said: I already have a very good Python code. But I want regex. The Python code (or other programming language) is the right solution. Regex doesn’t work the way you want it to, and do if you’ve got more than one swap to do per file, regex will not solve your problem.

1: False on both counts. Here is an example line <attribute id="Selectors" type="LSString" value="SelectSkills(ed664663-93b9-4070-a54b-3c7b19c0e7b4,3);SelectSpells(61f79a30-2cac-4a7a-b5fe-50c89d307dd6,2,0,BardCantrip,,,AlwaysPrepared);SelectSpells(dcb45167-86bd-4297-9b9d-c295be51af5b,4,0,BardSpells);SelectEquipment(aab8c5b5-eacf-4867-8e5f-bd4de3a9132e,1,BardInstrument);SelectAbilityBonus(b9149c8e-52c8-46e5-9cb6-fc39301c05fe,AbilityBonus,2,1)"/> There is a blank before, and sometimes there is something before and/or after it Otherwise, this is correct.

@Afik-Gilboa , “Everything running as Administrator” isn’t very helpful. I already linked you to ways to check so you can disable admin on Notepad++. Regarding permissions, unfortunately, because you didn’t share any information about those directories, or what the directory permissions are, or provide any directory listings, or anything like what I asked for, I will not be able to help you any further for now. If you ever decide you want help, feel free to provide actual information, rather than one sentence statements with nothing useful. Good luck.
