Reading data from interactive PDF-->XML

Hello frds,

Could you please help me on my new requirement  on reading data  from interactive PDF and generate in XML output.

I need to read data under Main menu(i.e Menu1, Menu2..etc) and its sub menu1,sub menu 2.

Eg: From Menu 1, I need to read data from Serial No, Message and Criticality under Issue Header Details heading  and data’s of (Data1,Data2 ,Value 1,Value 2 etc.)from sub menu 1 ,sub menu 2 etc. from Issue item details heading.

Since it was interactive PDF, when user click Menu 2 ,data from Serial No, Message and Criticality under Issue Header Details heading  and data (Data1,Data2 ,Value 1,Value 2 etc.)from sub menu 1 ,sub menu 2 etc. from Issue item details heading will changing.
