使用 Python beautifulSoup 抓取特定的 dd 項

Question

我正在嘗試使用 Python 從網站中提取特定的“dd”元素

headers = {'User-Agent': 'Mozilla/5.0 (X11; Linux x86_64) '\
           'AppleWebKit/537.36 (KHTML, like Gecko) '\
           'Chrome/75.0.3770.80 Safari/537.36'}

url = "https://www.ranger5g.com/forum/threads/pre-collision-assist.3239"
page = requests.get(url, headers=headers)
soup = BeautifulSoup(page.text, 'html.parser')


vehicle=[]

for i in soup.findAll("div", class_="message-userExtras"):
    for item in soup.find_all("dd")[::-1]:
        vehicle.append(item.get_text())
print(vehicle)

我正在嘗試從 url 中僅提取車輛列表，我的輸出應如下所示

2019 Ford Ranger XLT FX4
2019 Ford Ranger Lariat FX4, 1973 Mercury Capri
Tahoe/Tundra/Fusion
2019 Ford Ranger Lariat - Saber; 2014 GMC Terrain

但我的結果並不是我所期望的

Answer 1

使用正則表達式 re 並搜索帶有文本Vehicle的dt標簽，然后找到下一個dd標簽。

import re
from bs4 import BeautifulSoup
import requests
headers = {'User-Agent': 'Mozilla/5.0 (X11; Linux x86_64) '\
           'AppleWebKit/537.36 (KHTML, like Gecko) '\
           'Chrome/75.0.3770.80 Safari/537.36'}

url = "https://www.ranger5g.com/forum/threads/pre-collision-assist.3239"
page = requests.get(url, headers=headers)
soup = BeautifulSoup(page.text, 'html.parser')

for item in soup.find_all("div",class_='message-userExtras'):
    print(item.find('dt',text=re.compile("Vehicle")).find_next('dd').text.strip())

輸出：

2019 Ford Ranger XLT FX4
2019 Ford Ranger Lariat FX4, 1973 Mercury Capri
Tahoe/Tundra/Fusion
2019 Ford Ranger Lariat - Saber; 2014 GMC Terrain
