Question

我有以下元素：

<div class="column4">
        Unlimited Subscription<br/> Discount for Monthly <br/> Total Amount
    </div>

如何仅使用Beautiful Soup将三个字符串提取为三个不同的元素。不能使用字符串转换和正则表达式：

预期产出：

Unlimited Subscription
Discount for Monthly 
Total Amount

Answer 1

要获取单个字符串，您可以获取<select class="multiselect-success" multiple="multiple" name="categories[]"> <option value="1">laravel</option> <option value="2">nodejs</option> <option value="3">php</option> </select>元素的children并按类型过滤它们。

div

或更短，使用>>> bs = bs4.BeautifulSoup(html) >>> div = bs.find(attrs={"class":"column4"}) >>> [c.strip() for c in div.children if type(c) is bs4.element.NavigableString] ['Unlimited Subscription', 'Discount for Monthly', 'Total Amount']（如果您不想div.stripped_strings，则只需div.strings）：

strip

Answer 2

如果您希望以上面显示的方式获得输出，那么您可以遵守以下内容：

from bs4 import BeautifulSoup

html_elem ="""
<div class="column4">
    Unlimited Subscription<br/> Discount for Monthly <br/> Total Amount
</div>
"""
soup = BeautifulSoup(html_elem, 'lxml')
for item in soup.select(".column4"):
    for data in item.select("br"):data.replace_with("\n")
    print(item.text.strip())

输出：

Unlimited Subscription
Discount for Monthly 
Total Amount

Answer 3

from bs4 import BeautifulSoup
html_doc = """<div class="column4">
        Unlimited Subscription<br/> Discount for Monthly <br/> Total Amount
    </div>
"""
soup = BeautifulSoup(html_doc, 'html.parser')
soup.find("div").text.strip()
