What does error "AttributeError: 'NoneType' object has no attribute 'parse'" mean?
I use some code as below:
from xml.dom import minidom
xmldoc1 = minidom.parse('my.xml')
When I run it, I got error as below:
load_module xml
load_module xml.dom
load_module xml.dom.minidom
load_module xml.dom.expatbuilder
xml.dom.expatbuilder import failed
Traceback (most recent call last):
File "<string>", line 1, in ?
File "<string>", line 52, in load_module
File "CvEventInterface", line 13, in ?
File "<string>", line 52, in load_module
File "CvEventManager", line 12, in ?
File "<string>", line 52, in load_module
File "CvScreensInterface", line 16, in ?
File "<string>", line 52, in load_module
File "CvOptionsScreen", line 17, in ?
File "C:\Python24\lib\xml\dom\m
return expatbuilder.parse(file)
AttributeError: 'NoneType' object has no attribute 'parse'
Does anyone help me?

What do you mean "copy xml folder"? That's not the way you normally use python.
What happens if
cd C:\
python
import xml.dom.expatbuilder
If it fails you installation is not good.

I think Pythin is istanlled correctly without problems, because when I run code above in folder Python24, I got right result.
There is a application in different folder with its own python24, I added such code to its python source, when I run it, I got error "xml.dom not found".
So that I copy \Python24\lib\xml folder to that application's system folder, this time, the xml.dom.minidom is loaded, but I got error as ablove.
What can I do next?
