python lxml解析中文的问题

Question

使用lxml来抓取中文字符,抓到的结果很蛋疼,不知道怎么处理...

comUrl="http://m.51job.com/search/codetail.php?coid=4108723"
res=requests.get(comUrl)
html=etree.HTML(res.text)
p=html.xpath("//aside")[1].xpath("./p")   #结果为[<Element p at 0x7bf01c8>, <Element p at 0x78f4408>, <Element p at 0x69db388>]
p[0].xpath("./span/text()")  #这个是想要抓取的字符

结果抓到的是这样的 [u'xe6x80xa7xe8xb4xa8']
unicode但是内容是str的编码,请问怎么把这个东西转成中文?
正常应该是'xe6x80xa7xe8xb4xa8'或者u'u6027u8d28'

出现这种情况，一般是requests猜错了网页的编码了
因此指定requests的编码就可以了.
res.encoding ='utf-8'

In [33]: comUrl="http://m.51job.com/search/codetail.php?coid=4108723"
    ...: res=requests.get(comUrl)
    ...: res.encoding ='utf-8'
    ...: html=etree.HTML(res.text)
    ...: p=html.xpath("//aside")[1].xpath("./p")   #结果为[<Element p at 0x7b
    ...: f01c8>, <Element p at 0x78f4408>, <Element p at 0x69db388>]
    ...: p[0].xpath("./span/text()")  #这个是想要抓取的字符
    ...: 
Out[33]: [u'\u6027\u8d28']

In [34]: print _[0]
