find returns None when it doesn't find what you asked for. So you
can't check the .text attribute right away unless you want an
exception thrown. I deal with these annoyances like this:
sepelem = content.find(".//{http://www.huawei.com.cn/schema/common/v2_1}sepid";)
if sepelem is not None:
sepid = sepid.text
else:
sepid = ''
The empty string works for my purposes. Your script might need
something else.
