Insert blank pages in PDF using JavaScript when requirements met.

Hi there,

I need to insert blank pages in a large PDF doc only once after it finds a specific word on that page and is odd.

For eg:  If the page has the word "Print this document" and the page number is 5, then insert a blank page only after it.

             If the page has the word "Print this document" and the page number is 6, then insert a blank page before and after it.

             If the page does not have the word "Print this document", do nothing.

The code sounds simple but I am just not sure.

Thanks if anyone could help would really appreciate it.
