Показать все абзацы очищенного HTML-div в Django

Question

Итак, у меня есть извлеченный HTML-div с новостного сайта. Что это за фрагмент HTML:

<div class="cn-content">

<figure><img src="https://cimg.co/w/articles-attachments/1/5ca/71a090479e.jpg" sizes="(min-width: 640px) 720px, 100vw" srcset="https://cimg.co/w/articles-attachments/1/5ca/71a090479e.jpg 300w, https://cimg.co/w/articles-attachments/2/5ca/71a090479e.jpg 600w, https://cimg.co/w/articles-attachments/3/5ca/71a090479e.jpg 720w, https://cimg.co/w/articles-attachments/4/5ca/71a090479e.jpg 900w, https://cimg.co/w/articles-attachments/0/5ca/71a090479e.jpg 1337w" alt="OKEx Announced its First Token Sale via IEO 101" class="content-img"><figcaption>Source: iStock/baona</figcaption></figure>
<p>Major cryptocurrency exchange <b>OKEx</b> has announced an initial exchange offering (IEO) for the <b>BLOC</b> token, on their newly-presented OK Jumpstart token sale platform. The sale marks the first such endeavor of the exchange, joining the likes of <a href="https://cryptonews.com/ext/binance/" target="_blank" rel="nofollow noopener">Binance </a>and <a href="https://cryptonews.com/ext/bittrex/" target="_blank" rel="nofollow noopener">Bittrex </a>in the so-called killer app club.</p>
<p>The token in question is BLOC, native to the <b>Blockcloud</b> blockchain, and the sale is set to start at AM 12:00 UTC on April 10th. “Combining the advantages of blockchain and Future Internet technology, it reconstructs the technology layers below where current blockchain networks and Internet applications operate,” explains the project’s website. In short, it is a blockchain-based TCP/IP architecture, where TCP/IP is a suite of communication protocols used to interconnect network devices on the internet. </p>
<p>The token sale uses a subscription + allotment approach. Users will have a timeframe of 30 minutes to subscribe, and allotment will be based on the amount of the exchange’s native <a href="https://cryptonews.com/coins/okb/">OKB tokens</a> they hold over a seven-day period. The minimum threshold for a subscription is 500 OKB tokens (USD 1,145) held for those seven consecutive days, or buying in 3,500 OKB tokens on the last day - but to have their subscription guaranteed, users need to hold at least 2,500 OKB tokens daily or buy 17,500 OKB tokens on the final day before snapshot time.</p>
<p>The snapshots, which will be used to prove the users’ eligibility for participation, will be taken every day at AM 10:00 UTC, starting seven days before the token sale day. Then, users get their individual allotment coefficients based on the sum of OKB holdings in the moment of those snapshots. Users will have their individual subscription amounts in OKB locked up, and receive tokens based on a formula available on the OKEx blog. This formula bases the token allotment on both how many tokens users held during this period, as well as the amount of OKB they locked in as their subscription. </p>
<p>This move lets OKEx join the club of exchanges offering fundraising services. The latest example was Bittrex, where the token sale of <b>VeriBlock</b> tokens took a <a href="https://cryptonews.com/news/bittrex-beats-binance-in-selling-out-tokens-at-lightning-spe-3633.htm">mere 10 seconds</a>, beating even Binance’s speed of 22 seconds for the <b><a href="https://cryptonews.com/coins/fetch-ai/">Fetch.AI</a></b> token. Binance’s co-founder and CEO Changpeng Zhao coined the term “killer app” back in February, when he said in an interview that he views exchange-based fundraising as the next killer app.</p>
        </div>

Таким образом, в моих моделях я определил свойство для очистки этого HTML, поэтому я отображаю только текст абзаца, например:

@property
def description_clean(self):
    soup = BeautifulSoup(self.description)
    description = soup.find_all('div',attrs={"class":"cn-content"})
    for item in description:
        return item.find('p').text

Однако это только рендеринг первого абзаца, когда я использую это внутри шаблона с {{ post.description_clean }}

Вывод:

Крупная криптовалютная биржа OKEx объявила о первоначальном предложении биржи (IEO) для токена BLOC на своей недавно представленной платформе продажи токенов OK Jumpstart. Продажа знаменует собой первое подобное стремление к обмену, объединяя Binance и Bittrex в так называемом клубе приложений-убийц.

Почему другие абзацы не отображаются, потому что я зациклен на нем, правильно?

Answer 1

После получения тегов div вы не перебрали все теги p. Обновите свой код до этого:

@property
def description_clean(self):
    soup = BeautifulSoup(self.description)
    description = soup.find_all('div',attrs={"class":"cn-content"})
    p_tags = []  # result list
    for item in description:
        individual_p_tags = []  # preserve each individual "div"
        for p in item.find_all('p'):  # loop over all the "p" tags in each "div"
            individual_p_tags.append(p.text)  # append to a temp list
        p_tags.append("\n".join(individual_p_tags)) # convert the list to a string and append to the result list
    return p_tags  # this is a list of strings

Answer 2

вам нужно:

main_div = soup.find('div', attrs={"class": "cn-content"})
paragraphs = main_div.find_all('p')
for p in paragraphs:
    # save p text

Answer 3

Вы можете вернуть список абзацев

description = [item.text for item in soup.select('div.cn-content')]

, а затем

return description
