I'm very naive user for regex. I got an important task in limited time. I hope someone could look into it. Meanwhile I'll be trying from myside.
I've strings like
#: [Section]zNone
msgctxt "[Section]zNone"
msgid "None"
msgstr "Ninguno"
#: [Section]Search
msgid "Search"
msgstr "Búsquedas"
#: [Section]AdvancedSearch
msgid "Advanced Search"
msgstr "Búsqueda Avanzada"
For all msgstr"bla bla bla" strings should be replaced by msgstr "" using regex in file replace & find.
