PDF comparison with nodes

Hi, I am comparing two PDFs where the structure is very imp. Currently difference is showing in a result file by page numbers. I want to see the difference by nodes/ keys under which the values are different.

For ex - there are two PDF forms - Form 1 and Form 2 are supposed to be same and which have name, house no etc.

Form1 has Name as 'ABC' and Form2 has Name as 'XYZ'; when i compare Form 1 and Form 2, difference results should show - 

Desired : Form1 - Name field old as 'ABC' and new as 'XYZ'

Current : Page 1 - Old as 'ABC' and new as 'XYZ'
