我正在从仪表板上抓取一些数据,并且试图将多个div classes
内的一些数据放入pandas数据框中。我该如何尝试转换这样的东西:
[<div class="map-item" data-companyname="Apical Group" data-country="INDONESIA" data-district="Jakarta Utara" data-latitude="-6.099396000" data-longitude="106.951478000" data-millname="AAJ Marunda" data-province="Jakarta" data-report="http://naturalhealthytreat.com/sites/neste-daemeter.com/files/AAJ_Marunda.pdf" id="map_item_4645">AAJ Marunda</div>,
<div class="map-item" data-companyname="Apical Group" data-country="INDONESIA" data-district="Lubuk Gaung" data-latitude="1.754005000" data-longitude="101.363532000" data-millname="Sari Dumai Sejati" data-province="Riau" data-report="http://naturalhealthytreat.com/sites/neste-daemeter.com/files/Sari_Dumai_Sejati.pdf" id="map_item_4646">Sari Dumai Sejati</div>,
<div class="map-item" data-companyname="Kutai Refinery Nusantara " data-country="INDONESIA" data-district="Balikpapan" data-latitude="-1.179099000" data-longitude="116.788274000" data-millname="Kutai Refinery Nusantara " data-province="Penajam Paser Utara" data-report="http://naturalhealthytreat.com/sites/neste-daemeter.com/files/Kutai_Refinery_Nusantara_.pdf" id="map_item_4647">Kutai Refinery Nusantara </div>]
进入这样的数据框:
no companyname country district latitude longitude millname province report
1 Apical Group INDONESIA Jakarta Utara -6.099396 106.951478 AAJ Marunda Jakarta http://naturalhealthytreat.com/sites/neste-daemeter.com/files/AAJ_Marunda.pdf
2 Apical Group INDONESIA Lubuk Gaung 1.754005 101.363532 Sari Dumai Sejati Riau http://naturalhealthytreat.com/sites/neste-daemeter.com/files/Kutai_Refinery_Nusantara_.pdf
3 Kutai Refinery Nusantara INDONESIA Balikpapan -1.179099 116.788274 Kutai Refinery Nusantara Penajam Paser Utara http://naturalhealthytreat.com/sites/neste-daemeter.com/files/Kutai_Refinery_Nusantara_.pdf
到目前为止,这是我为了从网页上获取多个div类而编写的代码:
from bs4 import BeautifulSoup
import requests
# Link of Neste dashboard
url = 'http://nestetraceabilitydashboard.com/nestes-pfad-traceability-dashboard'
page = requests.get(url).content
soup = BeautifulSoup(page, "html.parser")
divList = soup.findAll('div', attrs={ "class" : "map-item"})
答案 0 :(得分:3)
我们可以使用.attrs
属性访问代码的属性。因此,我们可以创建一个包含所有标记属性的字典(class和id除外)并将其传递给数据帧。
from bs4 import BeautifulSoup
import requests
import pandas as pd
url = 'http://nestetraceabilitydashboard.com/nestes-pfad-traceability-dashboard'
page = requests.get(url).text
soup = BeautifulSoup(page, "html.parser")
divList = soup.findAll('div', attrs={"class" : "map-item"})
data = {}
for div in divList:
for k,v in div.attrs.items():
if k not in ('class', 'id'):
k = k.split('-')[1]
data[k] = data.get(k, []) + [v]
df = pd.DataFrame(data)
print(df.head(3))
数据框:

有关requests
最好使用.text
代替.content
,因为它包含已解码的响应内容(文本)。所以总是使用.text
,除非响应a是二进制文件(image,pdf等)。
关于BeautifulSoup
findAll
用于与bs3
向后兼容,bs4
将其重命名为find_all
。此外,您可以将属性用作keyword arguments,例如:
find_all('div', class_="map-item")
这里我使用class_
作为类属性,因为class
是Python关键字,但对于其他属性(id,href等),您可以按原样使用它们的名称。
