我正试图从这个 Wikipedia page 中抓取过生日的人
这是现有的代码:
hdr = {'User-Agent': 'Mozilla/5.0'}
site = "http://en.wikipedia.org/wiki/"+"january"+"_"+"1"
req = urllib2.Request(site,headers=hdr)
page = urllib2.urlopen(req)
soup = BeautifulSoup(page)
print soup
一切正常,我得到了整个 HTML 页面,但我想要特定数据,但我不知道如何在没有 id 的情况下使用 Beautiful Soup 访问它。 <ul>标签没有 ID,<li> 也没有标签。另外,我不能只要求每个 <li>标记,因为页面上还有其他列表。有没有特定的方法来调用给定的列表? (我不能只对这一页使用修复程序,因为我计划遍历所有日期并获取每一页的生日,而且我不能保证每一页的布局都与这一页完全相同)。
请您参考如下方法:
想法是获取带有 Births id 的 span,找到 parent 的下一个 sibling (即 ul)并迭代它的 li 元素。这是一个使用 requests 的完整示例(尽管它不相关):
from bs4 import BeautifulSoup as Soup, Tag
import requests
response = requests.get("http://en.wikipedia.org/wiki/January_1")
soup = Soup(response.content)
births_span = soup.find("span", {"id": "Births"})
births_ul = births_span.parent.find_next_sibling()
for item in births_ul.findAll('li'):
if isinstance(item, Tag):
print item.text
打印:
871 – Zwentibold, Frankish son of Arnulf of Carinthia (d. 900)
1431 – Pope Alexander VI (d. 1503)
1449 – Lorenzo de' Medici, Italian politician (d. 1492)
1467 – Sigismund I the Old, Polish king (d. 1548)
1484 – Huldrych Zwingli, Swiss pastor and theologian (d. 1531)
1511 – Henry, Duke of Cornwall (d. 1511)
1516 – Margaret Leijonhufvud, Swedish wife of Gustav I of Sweden (d. 1551)
...
希望对您有所帮助。
