global:[2017-06-05 10:27:48.662711] [ERROR] process_wechat_msg not well-formed (invalid token): line 1, column 301

import xml.etree.cElementTree as ET

xml_tree = ET.fromstring(fmsg_content)

运行报错

global:[2017-06-05 10:27:48.662711] [ERROR] process_wechat_msg not well-formed (invalid token): line 1, column 301

输出日志

fmsg_content[300:305] 得到的是特殊符号．、．

先尝试:

# parser = ET.XMLParser(encoding=‘utf-8‘)

# xml_tree = ET.fromstring(fmsg_content, parser=parser)

得到

*** Error in `/usr/bin/python3‘: double free or corruption (!prev): 0x00000000012ae500 ***

大坑。。
