我使用python的漂亮汤从特定的网站获取数据,但我不知道如何获得这些价格中的一个,但我想要以克(g)为单位的价格,如下所示,这是HTML:
<div class="promoPrice margBottom7">16,000
L.L./200g<br/><span class="kiloPrice">79,999
L.L./Kg</span></div>我使用以下代码:
p_price = product.findAll("div{"class":"promoPricemargBottom7"})[0].text
我的结果是:16,000 L.L./200g 79,999 L.L./Kg
但我想要: 16,000升/200克

您需要首先在div元素内对跨度执行decompose操作:
from bs4 import BeautifulSoup
h = """
<div class="promoPrice margBottom7">16,000 L.L./200g<br/>
<span class="kiloPrice">79,999 L.L./Kg</span></div>
"""
soup = BeautifulSoup(h, "html.parser")
element = soup.find("div", {'class': 'promoPrice'})
element.span.decompose()
print(element.text)
#16,000 L.L./200g发布于 2020-05-13 03:55:03
尝试使用soup.select_one('div.promoPrice').contents[0]
from bs4 import BeautifulSoup
html = """<div class="promoPrice margBottom7">16,000 L.L./200g<br/>
<span class="kiloPrice">79,999 L.L./Kg</span></div>"""
soup = BeautifulSoup(html, features='html.parser')
# value = soup.select('div.promoPrice > span') # for 79,999 L.L./Kg
value = soup.select_one('div.promoPrice').contents[0]
print(value)打印
16,000 L.L./200g
