How to scrape all the Company Names within Stockrover website using Selenium and Python-CodePudding

If this code below scrapes the first company name, IBM from a table, how would I code it to scrape all the company names from the first column in the table?

Pertinent Code:

table = wait.until(EC.presence_of_all_elements_located((By.CSS_SELECTOR, '#gridview-1070-record-2989')))

For instance, the next one I need is #gridview-1070-record-2990 and so on.

Current Result:

IBM

Desired Results:

IBM
Microsoft Corporation
Apple Corporation
Google
Tesla
etc.

from selenium import webdriver
from selenium.webdriver.support.ui import WebDriverWait

CodePudding user response：

To extract and print the texts e.g. IBM, Microsoft Corporation, etc from all of the <table> elements within the website stockrover, instead of presence_of_all_elements_located() you need to induce WebDriverWait for visibility_of_all_elements_located() and you can use either of the following Locator Strategies:

Using CSS_SELECTOR:

print([my_elem.text for my_elem in WebDriverWait(driver, 20).until(EC.visibility_of_all_elements_located((By.CSS_SELECTOR, "table[id^='gridview-1070-record']")))])

Using XPATH:

print([my_elem.text for my_elem in WebDriverWait(driver, 20).until(EC.visibility_of_all_elements_located((By.XPATH, "//table[starts-with(@id, 'gridview-1070-record')]")))])

Note : You have to add the following imports :

from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.common.by import By
from selenium.webdriver.support import expected_conditions as EC

CodePudding user response：

You can put the pertinent code in a for loop and then format the string inputted to search according to an index like so

table = []
for i in range(2989,"""the number of the last record you need"""):
table.append(wait.until(EC.presence_of_all_elements_located((By.CSS_SELECTOR, '#gridview-1070-record-{}'.format(i)))))

this will give you an array of the companies
