I need to control the order of the fields in the .xfdf.

My question is:
How do I control the field order in the .xfdf file?

I open the pdf file using Nuance PDF Converter Professional 5.
I put a blank space in every fillable field.
I save it.
I set the tabbing order.
I export the data to an .xfdf file.
I open the .xfdf file and look inside. Everything looks good. I have all the fieldnames and field values.

I go back in the form and change the tabbing sequence and save.
I export the data to an .xfdf file again.
I open the .xfdf file and look inside. I have all the fieldnames and field values but the order has not changed.

I need to control the order of the fields in the .xfdf.

Every year we get 200 new tax forms off the internet.
These forms don't have the same field names from year to year.
So, I need to control the order of the fields in the .xfdf to populate the right values in the right fields.

I sure can use your advise. Thanks.
