Concordion Java- Xml and PDF comparison

Hi there, I am looking for someone to build a java tool using concordion framwork.

Basically I have a xml file which creates a pdf file

What I want is comparing tool which compare 1pdf to 1 pdf and exclude fields mentioned in the XML file like for example date, customer number, amount which keeps changing, so i want to exclude those fields mentioned in the XML file.

Please message if you know how to do it with a screenshot or demo. I wont award you until i know that you know how to do it.

Thanks
Rayan :)
