setDocumentLocator in validating parser (xmlproc)

[Cees Wesseling]

Hi,

it seems that xmlproc, the default Validating parser, in my setup does
not call back to setDocumentLocator. Is there anyway to get a locator
in my handler?
Below you find an example and its output.

Regards, Cees

# base imports
from xml.sax.handler import ContentHandler
from xml.sax.handler import EntityResolver
import xml.sax
import xml.sax.sax2exts

class BaseHandler(ContentHandler):
    def setDocumentLocator(self,locator):
      print "setDocumentLocator called"
      self.d_locator=locator

    def startElement(self, name, attr):
      print "startElement", name


open('e.dtd','w').write('<!ELEMENT E EMPTY>')
open('e.xml','w').write(
"""<?xml version="1.0" encoding="ISO-8859-1"?>
   <!DOCTYPE E SYSTEM "e.dtd"><E/>""")

vp  = xml.sax.sax2exts.XMLValParserFactory.make_parser()
print "vp type",  vp.__class__
vph = BaseHandler()
vp.setContentHandler(vph)
vp.parse("e.xml")

np  = xml.sax.make_parser()
print "np type",  np.__class__
nph = BaseHandler()
np.setContentHandler(nph)
np.parse("e.xml")

OUTPUT:
vp type xml.sax.drivers2.drv_xmlproc.XmlprocDriver
startElement E
np type xml.sax.expatreader.ExpatParser
setDocumentLocator called
startElement E
