So now you come with information!
If you have the same pattern on other places too, it is normal that they are deleted there too.
And your statement (((search “de_DE@(.+?);”, it works correctly))) is not true,
as this removes the pattern on other place too as well with the normal Search&Replace dialog.
– – –
So conclusion, you can’t utilize RegEx here,
as for example “de_DE@(.+?);” would much on too many places:
de_DE@Produktkatalog;
de_DE@Zubehör;
de_DE@Ersatzteilkatalog;
de_DE@CAD;
de_DE@Näherungsschalter;
de_DE@00991619;
de_DE@Stromversorgung;
Better search for the complete unwanted strings:
de_DE@Stromversorgung;
ru_RU@Источники итания;
pl_PL@Zasilacz;
zh_CN@电源;
es_ES@Alimentación de corriente;
….
And next time, please provide better information at first place ;-)
Bye.
