Hi!

I have experienced following strange behaviour of
xmllib.XMLParser.handle_data()
method.
If I have XML tag whose body contains ']' the handle_data() method considers 
the ']' as separator (or what ?) and splits the whole text into pieces:

the source code:
-------------------
import xmllib
import sys

class MyXMLParser( xmllib.XMLParser ):
    
    i = 0

    def __init__( self ):
        xmllib.XMLParser.__init__( self )
        self.i = 0

    def unknown_starttag( self, tag, attributes ):
        print 'start tag: ' + tag + str( attributes )

    def unknown_endtag( self, tag ):
        print 'end tag: ' + tag

    def handle_data( self, data ):
        print self.i
        print type( data )
        print data
        self.i = self.i + 1

    def run( self, filename ):
        self.__init__()
        file = open( filename, 'r' )
        self.feed( file.read())
        self.close()
        file.close()

----------------------------------
the XML file sample:
----------------------------------
<?xml version="1.0"?>
<TEST>
  <NAME>
    Conversion from web speed [fpm] to motor speed [rpm] wrong (reference
calibration)
  </NAME>
</TEST>

end tag: NAME

end tag: TEST

----------------------------------------

I think this is a bug because the XML specification treats the ']' 
as valid data character.
W3C spec. -  [14] CharData ::= [^<&]* - ([^<&]* ']]>' [^<&]*) 

If I parse the example above with other XML parsers (MSXML and one Java based
parser) 
and they read it OK.
