在python中获取html标记值

您可以使用HTML解析器模块,例如 BeautifulSoup :

from bs4 import BeautifulSoup as BS
url ="mydomain.com"
usock = urllib2.urlopen(url)
data = usock.read()
usock.close()
soup = BS(data)
print soup.find('font', {'class':'big'}).text

这会找到一个标记 <font> 用一个 class="big" 。然后打印内容。

使用 lxml :

import urllib2
import lxml.html

url ="mydomain.com"

usock = urllib2.urlopen(url)
data = usock.read()
usock.close()
for font in lxml.html.fromstring(data).cssselect('font.big'):
    print font.text

>>> import lxml.html
>>> root = lxml.html.fromstring('<font class="big">Data</font>')
>>> [font.text for font in root.cssselect('font.big')]
['Data']
