I've changed the code to:

from xml.sax.handler import ContentHandler, ErrorHandler, DTDHandler, 
EntityResolver

class xpdf_parser:
   ...
   ...

from xml.sax import make_parser
from xml.sax.handler import feature_namespaces, feature_validation

if __name__ == '__main__':

      # create a parser
      parser = make_parser('xml.sax.drivers2.drv_xmlproc')
      # tell the parser we are not interested in XML namespaces
      parser.setFeature(feature_namespaces, 0)
      # tell the parser we want dtd validation
      parser.setFeature(feature_validation, 1)
      # create the handler
      pdf = xpdf_parser()
      # tell the parser to use our handler
      parser.setContentHandler(pdf)
      parser.setErrorHandler(pdf)
      parser.setDTDHandler(pdf)
      # Parse the input
      parser.parse(xpdf_file)

This is SAX2 correct ?

I also 'fixed' the DTD and the DTD warnings are gone ... but the 
TypeError remains. I'll look into the code, but if someone, who is 
more experienced with this module knows the answer .... please help 
me conserve some time. 

Kind Regards,
Remy
