Split PDF Files by Bookmarks

Can anyone please let me know how do I split PDF Files by bookmark using Java Script.

I am making a Visual Basic utility to read the bookmarks in PDF Files and split them based on the bookmarks. I am able to split the PDF Files by using Arts PDF Split Pro. However since I am already using Adobe Standard, I would like to do it with Adobe itself.

Thus, I pay license for only one software and not two.

Thanks
Rahul
