Hmm...  The builtin xml.dom.minidom and xml.sax both also fail to find 
the encoding:


 >>> import xml.dom.minidom as dom
 >>> dom.parseString('<?xml version="1.0" encoding="gbk"?>' + 
open(filename).read())
Traceback (most recent call last):
   File "<interactive input>", line 1, in ?
   File "C:\Program 
Files\Python\lib\site-packages\_xmlplus\dom\minidom.py", line 1925, in 
parseString
     return expatbuilder.parseString(string)
   File "C:\Program 
Files\Python\lib\site-packages\_xmlplus\dom\expatbuilder.py", line 942, 
in parseString
     return builder.parseString(string)
   File "C:\Program

in parseString
     parser.Parse(string, True)
ExpatError: unknown encoding: line 1, column 30


 >>> import xml.sax as sax
 >>> sax.parseString('<?xml version="1.0" encoding="gbk"?>' + 
open(filename).read(), sax.handler.ContentHandler())
