Hi,

Now at work, here are the details:

test.py:
from xml.sax import sax2exts
from xml.dom.ext import PrettyPrint
from xml.dom.ext.reader.Sax2 import FromXmlFile, Reader
import sys

class Resolver:
    def resolveEntity(self, publicId, systemId):
        print "resolve",publicId,systemId

file = "../xhtml/index.xhtml"
sys.stdout.writelines(open(file, "r").readlines())
#print file
#PrettyPrint(FromXmlFile(file))

parser = sax2exts.XMLParserFactory.make_parser()
parser.setEntityResolver(Resolver())
reader = Reader(parser=parser)
PrettyPrint(reader.fromStream(open(file)))

and the output (note no printing of entities in the second run, which
is missing the inverted exclamation mark and accented "o"):
