我正在為 Bookdepository 制作一個 webscrapper，但我遇到了該網站的 html 元素的問題。一本書的頁面有一個名為Product Details的部分，我需要從串列中獲取每個元素。但是，某些元素（并非全部）（例如Language ）具有此結構 sample image。怎么可能得到這個元素？
我正在進行的作業是這樣的。非常感謝提前

要獲得與<span>您的標簽相對應的標簽，您可以使用：
book_info.find_next(string='Language').find_next('span').get_text(strip=True)
獲取所有這些產品詳細資訊的更通用方法可能是：

Oprah'It is startlingly honest and, at times, a jaw-dropping read, charting her rise from poverty and abuse to becoming the first African-American to win the triple crown of an Oscar, Emmy and Tony for acting.' BBC NewsTHE DEEPLY PERSONAL, BRUTALLY HONEST ACCOUNT OF VIOLA'S INSPIRING LIFEIn my book, you will meet a little girl named Viola who ran from her past until she made a life changing decision to stop running forever.This is my story, from a crumbling apartment in Central Falls, Rhode Island, to the stage in New York City, and beyond. This is the path I took to finding my purpose and my strength, but also to finding my voice in a world that didn't always see me.As I wrote Finding Me, my eyes were open to the truth of how our stories are often not given close examination. They are bogarted, reinvented to fit into a crazy, competitive, judgmental world. So I wrote this for anyone who is searching for a way to understand and overcome a complicated past, let go of shame, and find acceptance. For anyone who needs reminding that a life worth living can only be born from radical honesty and the courage to shed facades and be...you.Finding Me is a deep reflection on my past and a promise for my future. My hope is that my story will inspire you to light up your own life with creative expression and rediscover who you were before the world put a label on you.show more",

您可以檢查標簽文本是否等于語言，然后列印文本。我還添加了一種更好的方法來在一次迭代中決議產品詳細資訊部分。
檢查下面給出的代碼： -

import re
book_isbn = ("9781399703994")
book_urls = "https://www.bookdepository.com/Enid-Blytons-Christmas-Tales-Enid-Blyton/" book_isbn
source = urlopen(book_urls).read()
soup = bs4.BeautifulSoup(source,'lxml')
book_info = soup.find('ul', class_='biblio-info')
lis=book_info.find_all('li')
# Check if the label name is Language and the print the span text
for val in lis:
label=val.find('label')
if label.text.strip()=='Language':
span=val.find('span')
span_text=(span.text.strip())
print('Language--> ' span_text)
# A better approach to get all the Name and value pairs in the Product details section in a single iteration
for val in lis:
label=val.find('label')
span=val.find('span')
span_text=(span.text.strip())
modified_text = re.sub('\n', ' ', span_text)
modified_text = re.sub(' ', ' ', modified_text)
print(label.text.strip() '--> ' modified_text)
