您需要
india在 显示的文本中 搜索单词。为此，您需要一个自定义函数：
from bs4 import BeautifulSoupimport requestsurl = "http://www.bbc.com/news/world/asia/"r = requests.get(url)soup = BeautifulSoup(r.content)india_links = lambda tag: (getattr(tag, 'name', None) == 'a' and 'href' in tag.attrs and 'india' in tag.get_text().lower())results = soup.find_all(india_links)
该
india_links拉姆达发现都是标记
<a>与链接
href属性，包含
india（不区分大小写）中显示的文本的地方。
注意，我使用了
requests响应对象
.content属性。将解码留给BeautifulSoup！
演示：
>>> from bs4 import BeautifulSoup>>> import requests>>> url = "http://www.bbc.com/news/world/asia/">>> r = requests.get(url)>>> soup = BeautifulSoup(r.content)>>> india_links = lambda tag: getattr(tag, 'name', None) == 'a' and 'href' in tag.attrs and 'india' in tag.get_text().lower()>>> results = soup.find_all(india_links)>>> from pprint import pprint>>> pprint(results)[<a href="/news/world/asia/india/">India</a>, <a href="/news/world-asia-india-30647504" rel="published-1420102077277">India scheme to monitor toilet use </a>, <a href="/news/world-asia-india-30640444" rel="published-1420022868334">India to scrap tax breaks on cars</a>, <a href="/news/world-asia-india-30640436" rel="published-1420012598505">India shock over Dhoni retirement</a>, <a href="/news/world/asia/india/">India</a>, <a href="/news/world-asia-india-30630274" rel="published-1419931669523"><img alt="A Delhi police officer with red flag walks amidst morning fog in Delhi, India, Monday, Dec 29, 2014.

注意
http://www.bbc.co.uk/news/world-radio-and-tv-15386555这里的链接；我们必须使用
lambda搜索，因为带有
text正则表达式的搜索不会找到该元素；包含的文本（
特殊报告：India Direct ）不是标签中的唯一元素，因此无法找到。
/news/world-asia-india-30632852链接也有类似问题。嵌套
<span>元素使得 法院提升印度BJP首席
标题文本不是link标记的直接子元素。
您可以提取 只 与链接：
from urllib.parse import urljoinresult_links = [urljoin(url, tag['href']) for tag in results]
相对于原始URL解析所有相对URL的位置：
>>> from urllib.parse import urljoin>>> result_links = [urljoin(url, tag['href']) for tag in results]>>> pprint(result_links)['http://www.bbc.com/news/world/asia/india/', 'http://www.bbc.com/news/world-asia-india-30647504', 'http://www.bbc.com/news/world-asia-india-30640444', 'http://www.bbc.com/news/world-asia-india-30640436', 'http://www.bbc.com/news/world/asia/india/', 'http://www.bbc.com/news/world-asia-india-30630274', 'http://www.bbc.com/news/world-asia-india-30632852', 'http://www.bbc.com/sport/0/cricket/30632182', 'http://www.bbc.co.uk/news/world-radio-and-tv-15386555', 'http://www.bbc.com/2/hi/south_asia/country_profiles/1154019.stm']
