Get HTML Code from a global content block

[Wishbone]

I don't think you'll be able to run CMS smarty functions externally. You might want to do something different like create a page containing the call to your GCB. The page is using a template that only contains {content}, and use cURL (or something) to access the data on that page.

Or... Write a UDT to leverage the AddGlobalContentPost trigger to write out the GCB to a file each time it's edited and have your script read this file.
