           Summary: SwissProt Parser error - cannot read recent SwissProt
                    entries
           Product: Biopython
           Version: 1.24
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: major
          Priority: P2
         Component: Main Distribution
        AssignedTo: biopython-dev at biopython.org
        ReportedBy: kris at math.princeton.edu


RX field of a SwissProt entry can, in newer records, be more than 1 line long,
while Sprot.py only accepts one line per record. See error message below. RX is
database reference of the article relevant to the entry, and Swissprot has
recently added DOI references as well. RA should be the next field after RX, but
if there are two RX lines in the record, parser chokes.
