Question

我正在尝试获取特定月份（例如网站上的 3 月）中的所有链接、标题和日期，我正在使用 BeautifulSoup 来执行此操作：

from bs4 import BeautifulSoup
import requests

html_link='https://www.pds.com.ph/index.html%3Fpage_id=3261.html'
html = requests.get(html_link).text
soup = BeautifulSoup(html, 'html.parser')
for link in soup.find_all('td'):
   #Text contains 'March'
   #Get the link title & link &date

我是 BeautifulSoup 的新手，在 Selenium 中我使用了 xpath："//td[contains(text(),'Mar')"，我如何使用 BeautifulSoup 执行此操作？

Answer 1

如果“日期”包含文本“三月”，则获取所有链接和标题：

查找“日期” - 找到所有包含文本“march”的 <td> 元素。
使用包含所需标题和链接的 .find_previous() 方法查找前一个 <a> 标记。

import requests
from bs4 import BeautifulSoup


url = "https://www.pds.com.ph/index.html%3Fpage_id=3261.html"
soup = BeautifulSoup(requests.get(url).content, "html.parser")

fmt_string = "{:<20} {:<130} {}"
print(fmt_string.format("Date", "Title", "Link"))
print('-' * 200)

for tag in soup.select("td:contains('March')"):
    a_tag = tag.find_previous("a")
    print(
        fmt_string.format(
            tag.text, a_tag.text, "https://www.pds.com.ph/" + a_tag["href"],
        )
    )

输出（截断）：

Date                 Title                                                                                                                              Link

Answer 2

这是您可以尝试的解决方案，

import re
import requests

from bs4 import BeautifulSoup

html_link = 'https://www.pds.com.ph/index.html%3Fpage_id=3261.html'
html = requests.get(html_link).text
soup = BeautifulSoup(html, 'html.parser')

search = re.compile("March")

for td in soup.find_all('td', text=search):
    link = td.parent.select_one("td > a")

    if link:
        print(f"Title : {link.text}")
        print(f"Link : {link['href']}")
        print(f"Date : {td.text}")
        print("-" * 30)
