Python - 使用 beautifulsoup 解析输入 html 数据并将输出数据按列存储在 csv 文件中

Question

我从邮件中提取 html 数据并用 beautifulsoup 解析这些数据。接下来，我想将解析后的数据存储在 csv 文件的正确标题下。但是，输入数据的文本不会相应地显示在输出 csv 文件中。

为 csv 文件解析输入数据 (fruits_html)：

Apples                        43        0       0                   0<br/>
Bananas                     2282        0     500                   0<br/>
Grapes                      2534        0     500                   0<br/>
Oranges                      274        0       0                   0<br/>
--------------------------------------------------------------------------------------------------<br/>

脚本：

# Parse raw messages to something readable
soup = BeautifulSoup(raw_email, 'html.parser')
fruits_html = soup.find_all('span')
headers = ["Names", "Quantity", "SpareQty", "MinQty", "MaxQty"]

with open('output.csv', 'w', newline='') as f_output:
    csv_output = csv.writer(f_output, delimiter=',')
    csv_output.writerow(headers)
    for br in soup.find_all('span'):
        csv_output.writerow([fruits_html for br in br.find_all('br')])

期望的输出：

我想将所有数量存储在 csv 文件的右侧标题下。不幸的是，我当前的输出在第一行显示标题，在第二行显示不同单元格中的大量<br/>。

import csv
from bs4 import BeautifulSoup
from bs4.element import NavigableString
data = '''
<html>
<span>

Apples                        43        0       0                   0<br/>
Bananas                     2282        0     500                   0<br/>
Grapes                      2534        0     500                   0<br/>
Oranges                      274        0       0                   0<br/>

</span>
</html>'''

soup = BeautifulSoup(data, 'html.parser')
#print(soup.find_all("span"))
headers = ["Names", "Quantity", "SpareQty", "MinQty", "MaxQty"]

with open('output.csv', 'w', newline='') as f_output:
    csv_output = csv.writer(f_output, delimiter=',')
    csv_output.writerow(headers)
    for br in soup.find_all("span"):
        for item in br.contents:
            if type(item) is not NavigableString:
                continue
            csv_output.writerow(item.strip().split())

带输出.csv

Names,Quantity,SpareQty,MinQty,MaxQty
Apples,43,0,0,0
Bananas,2282,0,500,0
Grapes,2534,0,500,0
Oranges,274,0,0,0
