lxml读取本地html文件,如何使用Python和lxml来解析本地html文件？

我在python中使用本地html文件,我正在尝试使用lxml来解析文件.由于某种原因,我无法正确加载文件,我不确定这是否与我的本地计算机上没有设置http服务器,etree用法或其他内容有关.

这是我的代码:

from lxml import html

import requests

page = requests.get('C:\Users\...\sites\site_1.html')

tree = html.fromstring(page.text)

test = tree.xpath('//html/body/form/div[3]/div[3]/div[2]/div[2]/div/div[2]/div[2]/p[1]/strong/text()')

print test

我得到的回溯读取:

C:\Python27\python.exe "C:/Users/.../extract_html/extract.py"

Traceback (most recent call last):

File "C:/Users/.../extract_html/extract.py", line 4, in

page = requests.get('C:\Users\...\sites\site_1.html')

File "C:\Python27\lib\site-packages\requests\api.py", line 69, in get

return request('get', url, params=params, **kwargs)
