运行报错

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。。
最终
fmsg_content=re.sub(u"[\x00-\x08\x0b-\x0c\x0e-\x1f]+",u"",fmsg_content)
xml_tree = ET.fromstring(fmsg_content)
替换掉非法字符 就不会报错了
