如何从具有div嵌入beautifulsoup4的div中获取第一个字符串

问题描述

我正在尝试从网站上提取价格.

I'm trying to extract prices from a website.

我编写的代码可以做到这一点，但是当网站的价格也显示旧价格时，它返回"none"而不是价格字符串.

The code I've written can do that, but when the website has a price that also shows the old price, it returns "none" instead of a string of the price.

这是不带旧价格的代码示例(我的代码以字符串形式返回)

This is an example of the code without the old price (which my code returns as a string)

<div class="xl-price rangePrice">
                            535.000 €
                        </div>

这是带有旧价格的代码示例(我的代码返回"none")

This is an example of the code WITH the old price (which my code returns as "none")

    < div


class ="xl-price rangePrice" >


487.000 €
< span


class ="old-price" > 497.000 € < br > < / span >

< / div >

我要从中提取代码的页面:页面链接

The page I'm trying to extract code from: pagelink

我的代码:

prices = []
for items in soup.find_all("div", {"class": "xl-price rangePrice"}):
    prices.append(items.string)

print(prices)

我遇到的另一个问题是它返回的值是这样的:

and another issue I'm having is that it returns the values like this:

'\r\n\t\t\t\t\t\t\t\t298.000 € \r\n\t\t\t\t\t\t\t', '\r\n\t\t\t\t\t\t\t\t145.000 € \r\n\t\t\t\t\t\t\t'

当我只想要数字时.

将感谢您的帮助！

推荐答案

import requests
from bs4 import BeautifulSoup

r = requests.get(
    'https://www.immoweb.be/en/search/apartment/for-sale/leuven/3000')
soup = BeautifulSoup(r.text, 'html.parser')

for item in soup.findAll('div', attrs={'class': 'xl-price rangePrice'}):
    item = item.contents[0]
    print(item.strip()[0:-1])

输出:

298.000
145.000
