python - 如何使用 BeautifulSoup 在 HTML 中提取折扣价

Question

我正在尝试练习和学习 BeautifulSoup，所以我尝试对在线商店进行网络解析。但是，我无法提取某些商品的某些价格，因为它们在 HTML 中有两个价格——原价和折扣价。雪上加霜的是，它们属于同一个 div 类和 span 类。

完整的 HTML 链接在这里:https://www.parkoutlet.com.ph/collections/mens-footwear?page=1

如果当前页面没有售罄或折扣价，您可以滚动到其他页面。

HTML Code Here

这是我当前的代码:

import urllib.request, urllib.parse, urllib.error
from bs4 import BeautifulSoup

url = "https://www.parkoutlet.com.ph/collections/mens-footwear"

# Opening the URL
html = urllib.request.urlopen(url).read()
soup = BeautifulSoup(html, "html.parser")

itemContainers = soup.findAll("div", {"class":"grid__item small--one-half medium-up--one-fifth"}) # Finds all the "Shoe Containers"

for container in itemContainers:
    brandContainer = container.findAll("div", class_="product-card__brand") # Brand Name
    brand = brandContainer[0].text

    nameContainer = container.findAll("div", class_="product-card__name") # Product Name
    name = nameContainer[0].text

    try:
        priceContainer = container.findAll("s", class_="product-card__regular-price") # Regular Price
        priceAvail = priceContainer[0].text
        print(priceAvail)

    except:
        noStock = container.findAll("div", class_="product-card__availability") # Sold Out
        print("SOLD OUT")

    print(brand)
    print(name)
    print("")

是的。品牌名称和商品名称都正确，但价格不正确。例如，第一个项目的价格应该是 P749，因为这是折扣价。

我目前是初学者，如果您在我的代码中看到除了无法获得折扣价之外的任何错误，请告诉我!

1.) 我如何在原价处于相同的 div 和 class 的情况下获得折扣价

2.) 我怎样才能使我的代码更有效率？有没有更好的方法来处理这个项目？

Answer 1

您可以使用此示例获取正常价格/销售价格/可用性:

import requests
from bs4 import BeautifulSoup

url = "https://www.parkoutlet.com.ph/collections/mens-footwear?page=1"
soup = BeautifulSoup(requests.get(url).content, "html.parser")

for item in soup.select(".grid__item.medium-up--one-fifth"):
    brand = item.select_one(".product-card__brand")
    name = item.select_one(".product-card__name")

    sale_price = ""
    normal_price = item.select_one(".product-card__regular-price")
    if normal_price:
        sale_price = normal_price.find_next().find_next_sibling(text=True)
    else:
        normal_price = item.select_one(".product-card__availability")

    print(brand.get_text(strip=True))
    print(name.get_text(strip=True))
    print(normal_price.get_text(strip=True))
    print(sale_price.strip())
    print("-" * 80)
