Python and XML

Hi!

I want to make an application that needs to parse an xml file, but I
always have weird errors, I've got Python 2.3

Here's the beginning of my prog:

from xml.dom import pulldom

and here's python's answer:

Traceback (most recent call last):
File "xml.py", line 1, in ?
from xml.dom import pulldom
File "C:\progs\xml.py", line 1, in ?
from xml.dom import pulldom
ImportError: No module named dom

When I look in my Python folder I see .py files in xml/dom...

Thanks for any help.

Please report

1. the output of

import xml
print xml.__file__

2. The contents of the directory printed above

3. The contents of the dom directory inside.

Regards,
Martin

In fact I've done all this things in the Python Shell, otherwise, when I
lauch it with "python foo.py" I've got the same kind of errors.
I think the problem comes from here, but I'm not skilled in Python, so...

Thanks

Sorry, I have no idea why it fails to find the dom package.

You have a file called 'xml.py' somewhere on the pythonpath, which is
replacing the normal 'xml' package.

However if it doesn't interfere when you try to import xml from the
interpreter, likelihood is it's an xml.py file in the same directory
as the program's script file - check there.

For some reason, the current working directory is included in Python's
default module search path, before all other directories. If anyone can
explain why this is the Right Thing I'd be interested to know.

I think the problem is that your program is called xml.py

so, when you say:

from xml import ....

it is trying to import from YOUR PROGRAM instead of the standard lib.
Try renaming your program.

you were right :)
Thanks a lot, I didn't know that python searched in the active directory
by default...

Use standard csv module if you want to produce csv ouput (

Here's some untested code to print the text values:

import xml.etree.ElementTree as ET

loadavg = ET.fromstring('<loadavg><one>0.00</one><five>0.00</five>'
'<fifteen>0.00</fifteen></loadavg>')

for interval_tag in ('one', 'five', 'fifteen'):
print(loadavg.findtext(interval_tag))

Re: python and xml [In reply to]

thank you Stefan. but the XML output is assigned to a variable; how to
process the variable with XML contents?

Hi,

Not sure what you mean. Maybe something like this?

xml = '<loadavg><one>0.00</one><five>0.00</five>...</loadavg>'
loadavg = ET.fromstring(xml)
