使用 Python 从网站抓取表数据

Question

I am trying to scrape below table data from a website using BeautifulSoup4 and Python link is: 1 : https://i.stack.imgur.com/PfPOQ.png

So far my code is

url = "https://www.boerse-frankfurt.de/bond/xs0216072230"
content = requests.get(url)
soup = BeautifulSoup(content.text, 'html.parser')
tbody_data = soup.find_all("table", attrs={"class": "table widget-table"})
table1 = tbody_data[2]
table_body = table1.find('tbody')
rows = table_body.find_all('tr')
 for row in rows:
        cols = row.find_all('td')
        print(cols)

With this code, I am getting result: Mycoderesult https://i.stack.imgur.com/C190u.png [Issuer, ] [Industry, ]

I see Issuer, Industry but value of Issuer and Industry not showing up by my result. Any help would be appreciated. TIA

Answer 1

You are not getting the entire output because data of second td of the table number 6 here is dynamically loaded via JavaScript.So you can mimic that using selenium with pandas.

import pandas as pd
from bs4 import BeautifulSoup
from selenium import webdriver
from selenium.webdriver.chrome.service import Service
import time
from selenium.webdriver.chrome.options import Options

webdriver_service = Service("./chromedriver") #Your chromedriver path
driver = webdriver.Chrome(service=webdriver_service)
url = 'https://www.boerse-frankfurt.de/bond/xs0216072230-fuerstenberg-capital-erste-gmbh-2-522'
driver.get(url)
driver.maximize_window()
time.sleep(3)
table=BeautifulSoup(driver.page_source, 'lxml')
df = pd.read_html(str(table))[5]
print(df)

Output:

Another solution, using just requests . Note, to obtain the result from the server one has to set required headers (the headers can be seen from the Developer tools -> Network tab).

import requests

url = (
    "https://api.boerse-frankfurt.de/v1/data/master_data_bond?isin=XS0216072230"
)

headers = {
    "X-Client-TraceId": "d87b41992f6161c09e875c525c70ffcf",
    "X-Security": "d361b3c92e9c50a248e85a12849f8eee",
    "Client-Date": "2022-08-25T09:07:36.196Z",
}

data = requests.get(url, headers=headers).json()
print(data)

Prints:
