I have a fix for the NPE but trying to also fix the under lining cause

The document has an extra line after PATN:

PATN

WKU  041584767
SRC  5
APN  8611106

Which ends up giving a blank value for PATN, note the space:

KeyValue [key=PATN, value= ], 
KeyValue [key=WKU, value=041584767], 
KeyValue [key=SRC, value=5],

Which gets mapped to incorrect XML, PATN should wrap all the fields:

<DOCUMENT><PATN> </PATN><WKU>041584767</WKU>

I should have a fix soon.
