SAX is the package 'xml.sax' distributed with Python 2.5:)
1,I read text from a GBK encoded XML file then I skip the first line
declare the encoding.
2,I converted the string to uncode by call decode('mbcs')
3,I used xml.sax.parseString to parse the string.

if n == 1:
s = s[i+1:]

s = '<root>'+s+'</root>'
s = s.decode('mbcs')
xml.sax.parseString(s,handler,handler)

I didn't tell the SAX the file is encoded in GBK since I used the
'parseString' method.

I mean SAX only support a limited number of encoding such as utf-8
utf-16 etc.,which didn't include GBK.

Frankly speaking, I cannot tell if the file contains any GB18030
