Thats the expected result, but it adds a second (third foruth and so on) dc_language element all the time From the documentation find() returns None if it finds nothing and in that case if adds it and sets the language ex_us.

So whats wrong with if not dc_language: ? If should not insert something, just changing.

Before:

  <metadata xmlns:dc="http://purl.org/dc/elements/1.1/" xmlns:opf="http://www.idpf.org/2007/opf">
    <dc:identifier id="BookId" opf:scheme="UUID">urn:uuid:7967fadc-d511-42ee-aad1-a472e662546a</dc:identifier>
    <dc:language>de</dc:language>
    <dc:title>[Title here]</dc:title>
  </metadata>

After

<?xml version="1.0" encoding="utf-8" ?>
<metadata xmlns:dc="http://purl.org/dc/elements/1.1/" xmlns:opf="http://www.idpf.org/2007/opf">
  <dc:identifier id="BookId" opf:scheme="UUID">urn:uuid:7967fadc-d511-42ee-aad1-a472e662546a</dc:identifier>
  <dc:language>de</dc:language>
  <dc:title>[Title here]</dc:title>
  <dc:language>en-US</dc:language>
</metadata>

By the way, the parser adds the xml starting declaration. At least, that doesnt mess up the content.opf file.



What my Python abilities now exceed is that if not dc_language statement does work. Debugging the code with print(): the content of the Variable is None
