In order to have Sax handle whitespace for you, you need:
 * a validating parser
 * a DTD for your document

You need to install python-xml on Debian to have a validating parser
(there are no validating parsers in python-xmlbase). 

With this package, you can get a validating parser with the following
code :

from xml.sax.sax2ext import XMLValParserFactory
parser = XMLValParserFactory.make_parser()

Then attach your handlers as usual. Ignorable whitespace should be
reported to the ContentHandler.ignorableWhitespace() method if you
provided it, and not to the characters() method.
