Simple xml, no idea about xpath for it

The rules order is important, i.e. the //* nontranslatable rule should be always the last one in the list.
Then it should work with either of your "1043"rules.

The thin is, that it is so:

Now, when I go to preview, I see this:

And this is what bothers me... The regex \\text\[@sprache="1043"] is correct, as I can visualize this in a Xpath visualizer and get only text with sprache="1043" shown. But Studio seems to completely ignore this...

Well, this is weird... I have now edited the file type, removed //*, added a position //text[@sprache="1043"] for each language, than defined all "sprache" but 1043 as non translatable and that worked.
So I added //* as non translatable and disabled all but 1043 - it worked again. So now I have this:

And this is what was needed - depending on the language the proper element can be enabled or disabled.

Thank you for your time looking into this issue.

Yep, there was an extra slash after "text" in your original XPath, that made the XPath incorrect.

It should be //text[@sprache="1043"].

That should be it - however I previously test bot with and without slash to no avail. Whatever happened, the problem is solved.
