用python美湯提取html元素

Question

我正在嘗試學習網絡抓取，並希望使用 python 從下面的 HTML blob 中提取價格$46.00-$50.00

<div class="organic-gallery-offer-section__price">
    <p class="elements-offer-price-normal medium" data-e2e-name="price@@normal" title="$46.00-$50.00"><span class="elements-offer-price-normal__price">$46.00-$50.00</span><span class="elements-offer-price-normal__unit">/ Piece</span></p>
    <p class="element-offer-minorder-normal medium" data-e2e-name="minOrder"><span class="element-offer-minorder-normal__value">2 Pieces</span><span class="element-offer-minorder-normal__suffix">(Min Order)</span></p>
</div>]

到目前為止，我編寫的代碼不起作用

item.findAll("div",{"class":"elements-offer-price-normal medium"})

Answer 1

有多種方法可以提取所需的文本，例如：

from bs4 import BeautifulSoup


txt = '''
<div class="organic-gallery-offer-section__price">
    <p class="elements-offer-price-normal medium" data-e2e-name="price@@normal" title="$46.00-$50.00"><span class="elements-offer-price-normal__price">$46.00-$50.00</span><span class="elements-offer-price-normal__unit">/ Piece</span></p>
    <p class="element-offer-minorder-normal medium" data-e2e-name="minOrder"><span class="element-offer-minorder-normal__value">2 Pieces</span><span class="element-offer-minorder-normal__suffix">(Min Order)</span></p>
</div>'''

soup = BeautifulSoup(txt, 'html.parser')

print(soup.find('span', class_="elements-offer-price-normal__price").text)

印刷：

$46.00-$50.00

或者：使用 CSS 選擇器：

print(soup.select_one('div.organic-gallery-offer-section__price span').text)
