cElementTree无效编码问题

xml python

我编码有问题,所以这可能很简单,但我卡住了。

我正在尝试解析通过电子邮件发送给的XML文件 App Engine 的新接收邮件功能。首先,我只是将XML粘贴到消息正文中,并使用CElementTree对其进行了良好的解析。然后我改为使用附件,用CElementTree解析它会产生以下错误:

前几行看起来是这样的:

GPX

 gpxcontent = message.bodies(content_type='text/plain')
 for x in gpxcontent:
   gpxcontent = x[1].decode()
 for event, elem in ET.iterparse(StringIO.StringIO(gpxcontent), events=("start", "start-ns")):

如果我使用Gmail将其作为附件附加到邮件中。然后按如下方式提取:

if isinstance(message.attachments, tuple):
      attachments = [message.attachments]
      gpxcontent = attachments[0][3].decode()
      for event, elem in ET.iterparse(StringIO.StringIO(gpxcontent), events=("start", "start-ns")):

我理解上面的错误。第3行第10列似乎是开始![CDATA在第三行。
