Python中的靓汤在某些wikipages中无法恢复属性

Question

它确实得到了Link1的坐标，但是同样的代码得到了另一个国家的坐标…为什么？（一年前效果不错）

link1='http://en.wikipedia.org/wiki/Ethiopia'
link2='http://en.wikipedia.org/wiki/Russia'

identification = { 'User-Agent' : 'Mozilla/4.0 (compatible; MSIE 5.5; Windows NT)'}
requestToServer2 = urllib2.Request(link2,headers=identification)
responseFromServerInHTML2 = urllib2.urlopen(requestToServer2)

subSoup = BS(responseFromServerInHTML2,'lxml')
coords=subSoup.find_all("span",{'class': 'geo'})[0].string

print coords

Answer 1

有两个geo类，findall可以同时获得：

link2='http://en.wikipedia.org/wiki/Russia'
import requests

from bs4 import BeautifulSoup
r = requests.get(link2)
soup = BeautifulSoup(r.content)
coords=soup.find_all("span",{'class': 'geo'})
print(coords)

[<span class="geo">60; 90</span>, <span class="geo">55.750; 37.617</span>]

如果需要第二个元素，只需访问第二个元素：

print(coords[1].text)
55.750; 37.617

您可以使用colspan查找第二个：

from bs4 import BeautifulSoup
r = requests.get(link2)
soup = BeautifulSoup(r.content)
print(soup.find("td",{'colspan': "2"})).find_next("span",{'class': 'geo'}).text
 55.750; 37.617
