#读取文件里的内容
from
lxml
import
etree
html
=
etree.parse(
'hello.html'
)
result
=
etree.tostring(html, pretty_print
=
True
)
print
(result)
|
获取li标签里的东西
| html = etree.parse('hello.html') print type(html) result = html.xpath('//li') print result print len(result) print type(result) print type(result[0]） |
