Hello Phil,
thanks for the new version 10.68 of Exiftool and thanks for the new features: e.g. to create a tag with "empty string" value.
Now I have the question:
Is it possible to differ between a non existing tag and an existing tag with "empty string" value in an e.g. -IF condition?
Doing some tests I did not find a solution.
Thanks for your comments in advance
Best regards
Herb
Hi Herb,
to find an undefined TAG:
-if "not defined $TAG"
to find an empty TAG:
-if "defined $TAG and not length $TAG"

Hello Phil,
thanks for your help.
Again I see that I should improve my Perl knowledge.
Best regards
Herb
