Process entire IPTC as user defined tag

[StarGeek]

Is it possible to make a user defined tag that will process an entire group, such as IPTC tags?  For example, let's say I want to trim all the IPTC entries of leading and trailing spaces, without necessarily knowing beforehand what tags are currently set, would that be possible?

I think you'll find that ExifTool already trims trailing spaces.

But the answer to your question is no.  There is no way to define an action to affect all tags (or all tags in a group).

That was just an example, but not all other programs do.

No worries then.
