cElementTree <type 'exceptions.SyntaxError'>: not well-formed (invalid token)

trying to scrape this xml file on the web with urllib and cElementTree. I am using Google App Engine but I don't think the problem is relevant to my platform.

This is my error:

<type 'exceptions.SyntaxError'>: not well-formed (invalid token): line 1, column 25
Traceback (most recent call last):

    return ET.parse(req, parser=parser)
  File "<string>", line 45, in parse
  File "<string>", line 28, in parse

The xml file is long but here is a sample:

<?xml version="1.0" encoding="windows-1252"?><veicoli>
<veicolo>

    </immagine>
</veicolo>
</veicoli>

My (simplified) code looks like this:

xml_url =   "http://www.shoppingcar.it/feed/export_vel.asp?parametro=1"
req =       urllib.urlopen(xml_url)
parser =    ET.XMLParser(encoding="windows-1252")
tree =      ET.parse(req, parser=parser).get_xml()

Here's the kicker: I downloaded and uploaded it as a public dropbox file. Using this url the xml parses just fine. I've tried without declaring the encoding, and tried windows-1252 and utf-8 encodings. It's just really strange because column 25 is nothing but the middle of the word "encoding". Any help is appreciated.

I tried your code (added imports, so that others can try):

#!/usr/bin/env python
import xml.etree.cElementTree as ET
import urllib

xml_url =   "http://www.shoppingcar.it/feed/export_vel.asp?parametro=1"
req =       urllib.urlopen(xml_url)
parser =    ET.XMLParser(encoding="windows-1252")
tree =      ET.parse(req, parser=parser).get_xml()

and it runs just fine. If your error only happens on the server then you probably hit a limit at the webpage and are trying to parse an error-message. So make sure that you are actually parsing the document (e.g. data = req.read() and then dump data and parse the string as xml.
