目的：得到title集合文本，content集合文本

代码：

#python2
import chardet
with open("news_sohusite_xml.dat",‘r‘) as h:
    x=h.readlines()
# print(x[3])

topics=x[3::6]
print(len(topics))
contents=x[4::6]

type = chardet.detect(x[3])
print(type)

# a = topics[0].decode(type["encoding"])

for i in topics:
    with open("sohusite_topics.txt","a") as f_out:
        f_out.write(i[14:-16].decode("gb18030").encode("utf-8")+‘\n‘)
#         f_out.write(i[14:-16].decode(type["encoding"]).encode("utf-8")+‘\n‘)

for i in contents:
    with open("sohusite_contents.txt","a") as f_outt:
        f_outt.write(i[9:-11].decode("gb18030").encode("utf-8")+‘\n‘)

解码编码上花了点时间：原本用chardet.detect可以得到文本编码是gb2312，但是decode的时候会报错：

UnicodeDecodeError ：‘gb2312‘ codec can‘t decode bytes：illegal multibyte sequence
