Web抓取标签之间的第二个数字

Question

我是Python的新手，从未做过HTML。因此，任何帮助都将不胜感激。我需要从网站的inspect元素中提取两个数字："1062"one_answers"348"。这是我的代码：

page = requests.get("https://www.traderscockpit.com/?pageView=live-nse-advance-decline-ratio-chart")
soup = BeautifulSoup(page.content, 'html.parser')
Adv = soup.select_one ('.col-sm-6 .advDec:nth-child(1)').text[10:]
Dec = soup.select_two ('.col-sm-6 .advDec:nth-child(2)').text[10:]

网站元素如下所示：

<div class="nifty-header-shade1 col-xs-12 col-sm-6 col-md-3">
<div class="row">
<div class="col-sm-12">
<h4>Stocks</h4>
</div>
<div class="col-sm-6">
<p class="advDec"><a href="/?pageView=nse-top-gainers" title="Click to view list of Advanced stocks">Advanced:</a> 1062</p>
</div>
<div class="col-sm-6">
<p class="advDec"><a href="/?pageView=nse-top-losers" title="Click to view list of Declined stocks">Declined:</a> 348</p>
</div>
</div>
</div>

使用我的代码，我能够提取第一个数字(1062(。但无法提取第二个数字(348(。你能帮忙吗。

Answer 1

假设Pattern总是相同的，您可以通过文本选择元素并获得其next_sibling:

adv = soup.select_one('a:-soup-contains("Advanced:")').next_sibling.strip()
dec = soup.select_one('a:-soup-contains("Declined:")').next_sibling.strip()

示例

import requests
from bs4 import BeautifulSoup
page = requests.get("https://www.traderscockpit.com/?pageView=live-nse-advance-decline-ratio-chart")
soup = BeautifulSoup(page.content)
adv = soup.select_one('a:-soup-contains("Advanced:")').next_sibling.strip()
dec = soup.select_one('a:-soup-contains("Declined:")').next_sibling.strip()
print(adv, dec)

Answer 2

如果总是有2个元素，那么最简单的方法可能是销毁所选元素的数组。

import requests
from bs4 import BeautifulSoup
page = requests.get("https://www.traderscockpit.com/?pageView=live-nse-advance-decline-ratio-chart")
soup = BeautifulSoup(page.content, "html.parser")
adv, dec = [elm.next_sibling.strip() for elm in soup.select(".advDec a") ]
print("Advanced:", adv)
print("Declined", dec)
