Output log

FMSG_CONTENT[300:305] got a special symbol. 、．

Try it first:

# parser = ET. Xmlparser (encoding= ' utf-8 ')

# Xml_tree = et.fromstring (fmsg_content, Parser=parser)

Get

Tai Hang.

Eventually

Fmsg_content=re.sub (U "[\x00-\x08\x0b-\x0c\x0e-\x1f]+", U "", fmsg_content)

Xml_tree = et.fromstring (fmsg_content)

Replacing illegal characters will not be an error.
