Tag values are ignored in JPEG XMP construction #5454
Description
Tag values (not attributes) are ignored when constructing the XMP from JpegImageFile.getxmp.
My (panorama) image has XMP (APP1):

<?xpacket end='w'?>Which currently Pillow resolves to:
{
'RDF': {},
'Description': {'about': ''},
'CroppedAreaImageHeightPixels': {},
'CroppedAreaImageWidthPixels': {},
'CroppedAreaLeftPixels': {},
'CroppedAreaTopPixels': {},
'FullPanoHeightPixels': {},
'FullPanoWidthPixels': {},
'ProjectionType': {},
'SourcePhotosCount': {},
'StitchingSoftware': {},
'UsePanoramaViewer': {},
}You can replicate the above result with:
import types
from PIL.JpegImagePlugin import JpegImageFile
content = b"""<paste XML from above>"""
im = types.SimpleNamespace(_xmp={}, applist=[("APP1", content)])
print(JpegImageFile.getxmp(im))My optimistic expectation would be:
{
"xmpmeta": {
"xmptk": "Image::ExifTool 11.88",
"RDF": {
"Description": {
"about": "",
"CroppedAreaImageHeightPixels": "7985",

},
},
},
