Scraping all entries of lazyloading page using python-CodePudding

See this page with ECB press releases. These go back to 1997, so it would be nice to automate getting all the links going back in time.

I found the tag that harbours the links ('//*[@id="lazyload-container"]'), but it only gets the most recent links.

How to get the rest?

from bs4 import BeautifulSoup
from selenium import webdriver
driver = webdriver.Firefox(executable_path=r'/usr/local/bin/geckodriver') 
driver.get(url)
element = driver.find_element_by_xpath('//*[@id="lazyload-container"]')
element = element.get_attribute('innerHTML')

CodePudding user response：

The data is loaded via JavaScript from another URL. You can use this example how to load the releases from different years:

import requests
from bs4 import BeautifulSoup

url = "https://www.ecb.europa.eu/press/pr/date/{}/html/index_include.en.html"

for year in range(1997, 2023):
    soup = BeautifulSoup(requests.get(url.format(year)).content, "html.parser")
    for a in soup.select(".title a")[::-1]:
        print(a.find_previous(class_="date").text, a.text)

Prints:

25 April 1997 "EUR" - the new currency code for the euro
1 July 1997 Change of presidency of the European Monetary Institute
2 July 1997 The security features of the euro banknotes
2 July 1997 The EMI's mandate with respect to banknotes

EDIT: To print links:


import requests

url = "https://www.ecb.europa.eu/press/pr/date/{}/html/index_include.en.html"

for year in range(1997, 2023):
    soup = BeautifulSoup(requests.get(url.format(year)).content, "html.parser")
    for a in soup.select(".title a")[::-1]:
        print(
            a.find_previous(class_="date").text,
            a.text,
            "https://www.ecb.europa.eu"   a["href"],
        )
