Hi I have an XML which gets converted to PDF , in the PDF I am able to generate the Page numbering , I have a specific requirement where I need to track and print a label for A perticular element about the number of pages it spawned in the entire PDF

Assume I have Element A some where in the middle of my XML and when i convert my XML to PDF , my total pages are 'x', and this perticular element starts at page say 'n' and spawns across next 'm' pages , I need to print a label in the footer section of the PDF some thing like this ' (Element A 1 of m pages). I am finding difficulty in getting this , any help is greatly appreciated
