我正在尝试从网站（https://carone.com.uy/autos-usados-y-0km?p=21）中提取几个值。有些工作正常，但有些不工作。例如，我能够提取名称、型号、价格和燃料类型，但无法正确提取“年份”或“公里数”字段，代码始终返回“N/A”作为值。
这是我正在使用的代码：
import pandas as pd
from datetime import date
import os
import socket
import requests
from bs4 import BeautifulSoup
def scrape_product_data(url):
try:
headers = {
"User-Agent": "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/58.0.3029.110 Safari/537.3"
}
product_data = []
# Make the request to get the HTML content
response = requests.get(url, headers=headers)
response.raise_for_status() # Check if the request was successful
soup = BeautifulSoup(response.text, 'html.parser')
product_elements = soup.find_all('div', class_='product-item-info')
for product_element in product_elements:
# Extract product name, price, model, and attributes as before (same code as previous version)
product_name_element = product_element.select_one('p.carone-car-info-data-brand.cursor-pointer')
product_name = product_name_element.text.strip() if product_name_element else "N/A"
product_price_element = product_element.find('span', class_='price')
product_price = product_price_element.text.strip() if product_price_element else "N/A"
product_model_element = product_element.select_one('p.carone-car-info-data-model')
product_model = product_model_element.get('title').strip() if product_model_element else "N/A"
# Extract product attributes
attributes_div = product_element.find('div', class_='carone-car-attributes')
year_element = attributes_div.find('p', class_='carone-car-attribute-title', text='Año')
year_value = year_element.find_previous_sibling('p', class_='carone-car-attribute-value').text if year_element else "N/A"
kilometers_element = attributes_div.find('p', class_='carone-car-attribute-title', text='Kilómetros')
kilometers_value = kilometers_element.find_previous_sibling('p', class_='carone-car-attribute-value').text if kilometers_element else "N/A"
fuel_element = attributes_div.find('p', class_='carone-car-attribute-title', text='Combustible')
fuel_value = fuel_element.find_previous_sibling('p', class_='carone-car-attribute-value').text if fuel_element else "N/A"
# Append product data as a tuple (name, price, model, year, kilometers, fuel) to the list
product_data.append((product_name, product_price, product_model, year_value, kilometers_value, fuel_value))
结果看起来像这样：enter image description here
我不明白为什么提到的值总是得到“N/A”，而其他的工作正常，方法是相同的。
问题是，该网站在元素的文本中使用的不是
Kilómetros，而是Kilómetros（年龄也是同样的情况）：def scrape_product_data(url): headers = { "User-Agent": "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/58.0.3029.110 Safari/537.3" } product_data = [] response = requests.get(url, headers=headers) response.raise_for_status() soup = BeautifulSoup(response.text, "html.parser") product_elements = soup.find_all("div", class_="product-item-info") for product_element in product_elements: product_name_element = product_element.select_one( "p.carone-car-info-data-brand.cursor-pointer" ) product_name = ( product_name_element.text.strip() if product_name_element else "N/A" ) product_price_element = product_element.find("span", class_="price") product_price = ( product_price_element.text.strip() if product_price_element else "N/A" ) product_model_element = product_element.select_one( "p.carone-car-info-data-model" ) product_model = ( product_model_element.get("title").strip() if product_model_element else "N/A" ) attributes_div = product_element.find("div", class_="carone-car-attributes") year_element = attributes_div.find( "p", class_="carone-car-attribute-title", string="Año" ) year_value = ( year_element.find_previous_sibling( "p", class_="carone-car-attribute-value" ).text if year_element else "N/A" ) kilometers_element = attributes_div.find( "p", class_="carone-car-attribute-title", string="Kilómetros" ) kilometers_value = ( kilometers_element.find_previous_sibling( "p", class_="carone-car-attribute-value" ).text if kilometers_element else "N/A" ) fuel_element = attributes_div.find( "p", class_="carone-car-attribute-title", string="Combustible" ) fuel_value = ( fuel_element.find_previous_sibling( "p", class_="carone-car-attribute-value" ).text if fuel_element else "N/A" ) product_data.append( ( product_name, product_price, product_model, year_value, kilometers_value, fuel_value, ) ) return pd.DataFrame( product_data, columns=["Name", "Price", "Model", "Year", "KM", "Fuel"] ) df = scrape_product_data("https://carone.com.uy/autos-usados-y-0km?p=2") print(df)打印结果：
