Setting a CDATA handler in Expat

Hi,

Can anyone tell me how to set a CDATA event handler in Python using Expat.
I'm currently using the Expat XML Parser (version 1.95.5).
And this is the Python code:

      outFile = file(localPlayerHtml, 'w')
      inFile = file(tempPlayerHtml, 'r')
      htmlparser = saxexts.make_parser()
      htmlhandler = PlayerHtmlHandler(outFile, stream)
      htmlparser.setDocumentHandler(htmlhandler)
      htmlparser.StartCdataSectionHandler = 
PlayerHtmlHandler.startCDATA     <-- here
      htmlparser.EndCdataSectionHandler = 
PlayerHtmlHandler.endCDATA       <-- and here
      htmlparser.parseFile(inFile)

The class PlayerHtmlHandler(saxlib.HandlerBase) in file 
PlayerHtmlHandler.py contains the following two functions:

   def startCDATA(self):
     print "Starting CDATA..."
     
   def endCDATA(self):
     print "Finishing CDATA..."

And I'm including the contents of PlayerHtmlHandler using the import 
statement:

from PlayerHtmlHandler import *

For some reason when I run the code, the two CDATA handlers are not called.

Can anyone see what I'm doing wrong?

Many thanks,
Frank.
