Except that I should be using a list and loop to do the null checking,
and it still stops when (I think) it hits a blank value:
TypeError: cannot concatenate 'str' and 'NoneType' objects
Perhaps this is what you intended to write:
if fname == "":
fname = "None"
and since None != "", you have to test for it:
if fname is None or fname == "":
fname = "None"
Note that doing this will deliberately write the text "None" whenever
the field is empty, so you will never get <FNAME></FNAME>, instead:
<FNAME>None</FNAME>. If you want to get the former, use: if fname is
None: fname = ""
