I'm deeply sorry, but the forms I have are strictly confidential, but I can suggest that you use phone billings, for example, in my family's phone billings I can find next:
- logos and key value pairs (in each page there is a key value pair denoting the mobile phone that the page is referring to, for example, my son's phone)
- complex tables, in each page you can find different tables for national, international or other type of calls, but at the end the structure of this tables and their fields are the same, but maybe not the table's location.
it is important the first point, at the end all tables are the same kind, but in the details of the page there is a code that differentiates it; if you are able to get the tables, but you can not differentiate them, then you got only a partial solution (one trick can be to process every page independently)
Regards.
