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。
