我正在尝试使用Python从网站中提取特定的'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)
我正在尝试仅从网址中提取车辆列表，我的输出应如下所示
2019 Ford Ranger XLT FX4
2019 Ford Ranger Lariat FX4, 1973 Mercury Capri
Tahoe/Tundra/Fusion
2019 Ford Ranger Lariat - Saber; 2014 GMC Terrain
但是我的结果不是我所期望的
使用正则表达式re并dt用文本搜索标签，Vehicle然后找到下一个dd标签。
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())
输出：
