这里需要使用xpath提取数据
要提取的数据
4 Door Sedan
4 Cylinder, 1.8 Litre
Constantly Variable Transmission, Front Wheel Drive
Petrol - Unleaded ULP
6.4 L/100km
试过这个:
import requests
import lxml.html as lh
import pandas as pd
import html
from lxml import html
from bs4 import BeautifulSoup
import requests
cars = []
urls = ['https://www.redbook.com.au/cars/details/2019-honda-civic-50-years-edition-auto-my19/SPOT-ITM-524208/']
for url in urls:
car_data={}
headers = {'User-Agent':'Mozilla/5.0'}
page = (requests.get(url, headers=headers))
tree = html.fromstring(page.content)
if tree.xpath('/html/body/div[1]/div[2]/div/div[1]/div[1]/div[4]/div/div'):
car_data["namings"] = tree.xpath('/html/body/div[1]/div[2]/div/div[1]/div[1]/div[4]/div/div')[0]
最佳答案
你已经导入了 BeautifulSoup 那么为什么不使用 css 类选择器呢？
import requests
from bs4 import BeautifulSoup as bs
r = requests.get('https://www.redbook.com.au/cars/details/2019-honda-civic-50-years-edition-auto-my19/SPOT-ITM-524208/', headers = {'User-Agent':'Mozilla/5.0'})
soup = bs(r.content, 'lxml')
info = [i.text.strip() for i in soup.select('.dgi-')]
你也可以打印为
for i in soup.select('.dgi-'):
print(i.text.strip())
