Yes, the problem is that keys does not contain any items.  The 'weird' names
are not the problem, because i tried it also with regular 1-word names (no
slashes), with the same results.  Also, the keys=form.keys() line is
properly indented in the code -- it was just a copy/paste problem.  Here is
the code again, with the extraneous stuff stripped out:

#!/usr/local/bin/python

import cgitb; cgitb.enable()
import sys, traceback, cgi

def main():
    try:
        form = cgi.FieldStorage()
        input = form.keys()

        print "Content-type: text/html\n\n"
        print("""<?xml version='1.0' encoding='UTF-8'?>
        <!DOCTYPE html PUBLIC '-//W3C//DTD XHTML 1.1//EN'
'http://www.w3.org/TR/xhtml11/DTD/xhtml11.dtd'>
        <html xmlns='http://www.w3.org/1999/xhtml' xml:lang='en'>
            <head>
                <title>test</title>
            </head>
            <body>""")
        print "<p>",keys,"</p>"
        print "</body></html>"
   except:
        pass

if __name__ == "__main__":
     main()

And the form is:

<form action="http://someurl.com/cgi-bin/updatexml.py" method="post">
     <input type="text" name="Name" size="20" />
     <input type="text" name="PartNumber" size="20" />
     <input type="text" name="Inventory" size="20" />
     <input type="text" name="Cost" size="20" />
     <input type="text" name="WholesalePrice" size="20" />
    <input type="submit" value="Update Records" />
</form>

The script, again, is currently just supposed to return the keys, which I am
expecting to be Name, PartNumber, etc., but it returns only an empty list.
Any ideas.

thanks,
