ElementTree is None if defusedxml is unavailable, triggering this warning.

OK, let's also add a match= to pytest.warns to make it a bit clearer (this and the other one).

Sure, done, and I've added it to other locations as well.

Resolves #7273
Resolves #7324
The JPEG XMP code was originally added in #5144. The image in #7273 differs in that it is padded at the end with b"\x00". I've updated the JpegImagePlugin code to allow for that.
The image in #7273 also has an attribute name that doesn't contain a semicolon. Normally, the tags do, and leads to the start of the tag being surrounded with curly brackets. Their absence causes an error at the moment, so I've also added a commit to allow for that.
I created the test files by copying the XMP data from Tests/images/xmp_test.jpg, modifying it to trigger these conditions, and saving new images with a modified Pillow.
