Scraping a React-table using Selenium

问题

I have written a code for scaping an HTML React table by using python selenium. But it cannot catch values in the table(only DOM elements). Here is the website https://nonfungible.com/market/history/decentraland?filter=saleType%3D&length=10&sort=blockTimestamp%3Ddesc&start=0 Here is my code:

from selenium import webdriver
dr = webdriver.PhantomJS(r'PATH_TO_PHANTOM/phantomjs-2.1.1-macosx/bin/phantomjs')
dr.get("https://nonfungible.com/market/history/decentraland?filter=saleType%3D&length=10&sort=blockTimestamp%3Ddesc&start=0")
table = dr.find_elements_by_class_name("rt-tr-group")
for item in table:
    headers = ",".join([th.text for th in item.find_elements_by_class_name("rt-td")])
    print(headers)

It just prints nothing.

Thank you for helping!

If you intend to use ChromeDriver and google-chrome you can use the following Locator Strategy:

• Code Block:

  driver.get("https://nonfungible.com/market/history/decentraland?filter=saleType%3D&length=10&sort=blockTimestamp%3Ddesc&start=0")
  print([my_elem.text for my_elem in WebDriverWait(driver, 20).until(EC.visibility_of_all_elements_located((By.CSS_SELECTOR, "div.rt-tr-group div.rt-td")))])
  

• Console Output:
