“在 div 標簽中提取文本”但給出錯誤

Question

這是一段代碼，我想提取文本“ Available at Amazon starting at $200"售”。這是我到目前為止所寫的

import re
Cost_List = []
for result in stroller_result:
    if result.find('div', class_ = 'product__retailer__text') is not None:
        Cost = result.find_all('div', {'class': ["product__retailer__text", re.compile(r'\$\d+(?:\.\d+)?')]})
    Cost_List.append(Cost)

此代碼返回：

[[<div class="product__retailer__text">Available at Amazon starting at $200</div>],
 [<div class="product__retailer__text">Available at Amazon starting at $200</div>],
 [<div class="product__retailer__text">Available at Amazon starting at $500</div>],
 [<div class="product__retailer__text">Available at Amazon starting at $100</div>],
 [<div class="product__retailer__text">Available at Amazon starting at $100</div>],

如果我嘗試提取文本，我確實會收到此錯誤： 'Available at Amazon starting at $200' using.text I get the following error - AttributeError: ResultSet object has no attribute 'text'. You're probably treating a list of items like a single item. Did you call find_all() when you meant to call find()?

    Cost_List.append(Cost)

Answer 1

為了擺脫你的錯誤，你可以在每個元素上調用.text ，而不是在元素列表上。

import re
Cost_List = []
for result in stroller_result:
    if result.find('div', class_ = 'product__retailer__text') is not None:
        Cost = result.find_all('div', {'class': ["product__retailer__text", re.compile(r'\$\d+(?:\.\d+)?')]})
        Cost = [el.text for el in Cost]
        Cost_List.append(Cost)

Answer 2

此代碼有效：

import re
Cost_List = []
for result in stroller_result:
    if result.find('div', class_ = 'product__retailer__text') is not None:
        Cost = [x.text for x in result.find_all('div', {'class': ["product__retailer__text", re.compile(r'\$\d+(?:\.\d+)?')]})]
    Cost_List.append(Cost)
