python - 精确 标签值时出错 - BeautifulSoup

Question

我正在使用 BeautifulSoup 进行网页抓取。我有这段代码来提取 a 标签的值，但它似乎不起作用。显示错误:

AttributeError: 'int' object has no attribute 'text'

这里是代码:

import requests
from bs4 import BeautifulSoup

url = "http://www.example.com"

page  = requests.get(url).text
soup_expatistan = BeautifulSoup(page)

expatistan_table = soup_expatistan.find("div", id="country-box")

expatistan_titles = expatistan_table.find_all("ul", class_="unstyled flat")[1]
#print (expatistan_titles)
for expatistan_title in expatistan_titles:
     print (expatistan_title.find("a").text) """ Error on this line """

我已验证 expatistan_title 输出包含:

<li class=""> <a href="http://www.wotif.com/AR" class="multiselect__option js-country-selector " data-id="AR">Argentina</a>
</li>
 <li class=""> <a href="http://www.wotif.com/AU" class="multiselect__option js-country-selector " data-id="AU">Australia</a>
 </li>
 <li class=""> <a href="http://www.wotif.com/AT" class="multiselect__option js-country-selector " data-id="AT">Austria</a>
 </li>

Answer 1

expatistan_titles = expatistan_table.find_all("ul", class_="unstyled flat")[1]

导致expatistan_titles成为单个元素，而不是列表。然后逐个字符地迭代它，调用 find()在每个上返回字符串中子字符串的 int 位置。当然，int 对象上没有 text 属性。

就这样吧:

expatistan_titles = expatistan_table.find_all("ul", class_="unstyled flat")[1]
for expatistan_title in expatistan_titles.find_all('li'):
     print (expatistan_title.find("a").text)

此外，您可以使用 CSS Selectors 来简化代码，只需 2 行:

for link in soup.select('div#country-box ul.unstyled.flat li a'):
    print(link.text)
