How to change wrong xml:lang in multiple files?
I have books in English and German in my library. When I add a new book, I download the metadata, do an EPUB to EPUB conversion and then polish it. I don't know when this error occured, but suddenly all my German books have the wrong language tag embedded in the title page file.
When I open an EPUB in German with the editor, the titlepage shows this line:
<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en">.
Is there a way to change this to xml:lang="de" in all affected EPUB files at once?
