I'm trying to crawl the website "http://everydayhealth.com". However, I found that the page will dynamically rendered. So, when I click the button "More", some new news will be shown. However, using splinter to click the button doesn't let "browser.html" automatically changes to the current html content. Is there a way to let it get newest html source, using either splinter or selenium? My code in splinter is as follows:
import requests
from bs4 import BeautifulSoup
from splinter import Browser
browser = Browser()
browser.visit('http://everydayhealth.com')
browser.click_link_by_text("More")
print(browser.html)
Based on @Louis's answer, I rewrote the program as follows:
from selenium import webdriver
from selenium.webdriver.support.ui import WebDriverWait
driver = webdriver.Firefox()
driver.get("http://www.everydayhealth.com")
more_xpath = '//a[@class="btn-more"]'
more_btn = WebDriverWait(driver, 10).until(lambda driver: driver.find_element_by_xpath(more_xpath))
more_btn.click()
more_news_xpath = '(//a[@href="http://www.everydayhealth.com/recipe-rehab/5-herbs-and-spices-to-intensify-flavor.aspx"])[2]'
WebDriverWait(driver, 5).until(lambda driver: driver.find_element_by_xpath(more_news_xpath))
print(driver.execute_script("return document.documentElement.outerHTML;"))
driver.quit()
However, in the output text, I still couldn't find the text in the updated page. For example, when I search "Is Milk Your Friend or Foe?", it still returns nothing. What's the problem?
With Selenium, assuming that driver
is your initialized WebDriver
object, this will give you the HTML that corresponds to the state of the DOM at the time you make the call:
driver.execute_script("return document.documentElement.outerHTML;")
The return value is a string so you could do:
print(driver.execute_script("return document.documentElement.outerHTML;"))
