This is to let you know: i have tested again, and now it seems really good.
The processing time is very good (few minutes to process a 1 GB XML file).
The 'tables' also seems fine. What I'll do next is to compare its data (validate).
I have macros that "start" from the exported dump and create reports. For example, the Hunter Baseline.
If the exported data is fine, i think i will start using it as 'parser' for the Hunter Tools.
I'll let you know soon.
Thank You again.
