Is there a way to test if a tag/content exists before I try to use it?
I mean, if I try to "findline" a tag that maybe exists maybe not like "Screenwriters" or "Studio" in iTunes website the script abort the process. I don't this behavior.
I just want the command returns nothing.
Is there a way to implement a "foreach" to loop some tag/content?
"Do" doesn't work well, I can't Nest this command.
"Aborted: ERROR(L359/do): nesting of do command not allowed"
