Question

我正在尝试抓取网页并将结果存储在csv / excel文件中。我正在为此使用漂亮的汤。

我正在尝试使用find_all函数从汤中提取数据，但是我不确定如何在字段名称或标题中捕获数据

HTML文件具有以下格式

<h3 class="font20">
 <span itemprop="position">36.</span> 
 <a class="font20 c_name_head weight700 detail_page" 
 href="/companies/view/1033/nimblechapps-pvt-ltd" target="_blank" 
 title="Nimblechapps Pvt. Ltd."> 
     <span itemprop="name">Nimblechapps Pvt. Ltd. </span>
</a> </h3>

到目前为止，这是我的代码。不确定如何从这里继续

from bs4 import BeautifulSoup as BS
import requests 
page = 'https://www.goodfirms.co/directory/platform/app-development/iphone? 
page=2'
res = requests.get(page)
cont = BS(res.content, "html.parser")
names = cont.find_all(class_ = 'font20 c_name_head weight700 detail_page')
names = cont.find_all('a' , attrs = {'class':'font20 c_name_head weight700 
detail_page'})

我尝试使用以下-

Input: cont.h3.a.span
Output: <span itemprop="name">Nimblechapps Pvt. Ltd.</span>

我想提取公司的名称-“ Nimblechapps Pvt。Ltd。”

Answer 1

您可以为此使用列表理解：

from bs4 import BeautifulSoup as BS
import requests

page = 'https://www.goodfirms.co/directory/platform/app-development/iphone?page=2'
res = requests.get(page)
cont = BS(res.content, "html.parser")
names = cont.find_all('a' , attrs = {'class':'font20 c_name_head weight700 detail_page'})
print([n.text for n in names])

您将获得：

['Nimblechapps Pvt. Ltd.', (..) , 'InnoApps Technologies Pvt. Ltd', 'Umbrella IT', 'iQlance Solutions', 'getyoteam', 'JetRuby Agency LTD.', 'ONLINICO', 'Dedicated Developers', 'Appingine', 'webnexs']

Answer 2

相同，但使用后代组合器" "将类型选择器a与attribute = value选择器[itemprop="name"]组合起来

names = [item.text for item in cont.select('a [itemprop="name"]')]

Answer 3

尽量不要在脚本中使用复合类，因为它们容易被破坏。以下脚本也应获取您所需的内容。

import requests
from bs4 import BeautifulSoup

link = "https://www.goodfirms.co/directory/platform/app-development/iphone?page=2"

res = requests.get(link)
soup = BeautifulSoup(res.text, 'html.parser')
for items in soup.find_all(class_="commoncompanydetail"):
    names = items.find(class_='detail_page').text
    print(names)
