Question

我有以下代码为我提供了此输出（每个链接以“，”分隔）。

ids = soup.find_all("tr",{"class":"table-row"})
#ids = soup.findAll("span",{"class": "text-nowrap"})
ids

其中一个链接的示例如下

                            <tr _ngcontent-sc371="" class="table-row">
                                <td _ngcontent-sc371="" class="table-col">
                                    <a _ngcontent-sc371="" data-gtm="address" class="text-primary font-weight-bolder text-left" href="/salg/info/326/25402/A5694110-6CCD-431B-B86D-D9B87CD062F6">

我不确定如何从这里继续进行操作，以使价值观得到体现。我的目标是将其存储在DataFrame中，例如，我拥有列名和相应的值（基于链接）Salgsdato（22-09-2020），地址（Svalevaanget 20），Koobesom（995.000），m² （82）。

有人提供一些有用的指导吗？

要从文档创建数据框并将其保存为CSV，可以使用以下示例（txt是问题中的HTML代码段）：

import pandas as pd
from bs4 import BeautifulSoup

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

# remove mobile-headings
for mh in soup.select('.mobile-heading'):
    mh.extract()

all_values = []
for tr in soup.select('tr.table-row'):
    tds = [td.get_text(strip=True, separator=' ') for td in tr.select('td')]
    all_values.append(tds)

df = pd.DataFrame(all_values, columns=['Address', 'Koobesom', 'Salgsdato', 'Boligtype', 'Kr. / m²', 'Værelser', 'm²', 'Byggear', 'Prisjustering'])
df.to_csv('data.csv')
print(df)

打印：

                            Address Koobesom  ... Byggear Prisjustering
0  Svalevaanget 20, 4400 Kalundborg  995.000  ...    1971              

[1 rows x 9 columns]

并创建data.csv（来自LibreOffice的屏幕截图）：
