If I run the following code 10 times in a row, it will work about half the time and fail the rest. Anyone know why?

import urllib2, cookielib, re, os, sys

class Facebook():
    def __init__(self, email, password):
        self.email = email
        self.password = password

        cj = cookielib.CookieJar()
        opener = urllib2.build_opener(urllib2.HTTPCookieProcessor(cj))
        opener.addheaders = [('Referer', 'http://login.facebook.com/login.php'),
                            ('Content-Type', 'application/x-www-form-urlencoded'),
                            ('User-Agent', 'Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9.1.7) Gecko/20091221 Firefox/3.5.7 (.NET CLR 3.5.30729)')]
        self.opener = opener

    def login(self):
        url = 'https://login.facebook.com/login.php?login_attempt=1'
        data = "locale=en_US&non_com_login=&email="+self.email+"&pass="+self.password+"&lsd=20TOl" …

我在网页上有以下 xml -

我正在尝试解析这些数据。我有一个通过请求 -

r = requests.get(url, auth=('username', 'password'))

但是当我尝试解析内容时出现错误。

>>> xmlObject = etree.parse(r.content)
