How can I extract the value of latitude from table body?

Question

I can't seem to figure out how to return on integer from a table body. The terminal is returning a 'none' type and if I get rid of get.attribute("value") on line 10 nothing prints to the terminal.

from bs4 import BeautifulSoup as bs
import requests
from selenium import webdriver 

driver = webdriver.Safari()
url = driver.get('http://wsn.spaceflight.esa.int/iss/index_portal.php')

#able to get element from web but returning 'none' value in terminal
latitude = driver.find_element_by_xpath('//tbody/tr[1]/td[2]/div')

print(latitude.get_attribute("value"))#something I tried, not working
driver.close()

From inspecting the webpage; you may need to try:

latitude = driver.find_element_by_xpath('//tbody/tr[1]/td[1]/div[2]')

Or this; since it has an ID:

latitude = driver.find_element_by_xpath('//*[@id="isst_lat"]')

And to get the content:

latitude.text

It is a string.

The second part outputs a selenium object. Like so, , which I've gotten before but now how do I get that object to display an integer? – Aug 28 '19 at 04:11
I have updated the comment. Call the `.text` and you will get the co-ordinate. It is a string and not an integer. – Nidhin Bose J. Aug 28 '19 at 04:31
@NidhinBoseJ. You can parse the String to Integer – Ashok kumar Ganesan Aug 28 '19 at 04:54
But I would not know its significance since the output is co-ordinates and hence its unit is not exactly expressed with a float. – Nidhin Bose J. Aug 28 '19 at 05:02

you can get the long and lat with below lines.

longitude = driver.find_element_by_xpath("//div[@id='isst_lon']").text
latitude = driver.find_element_by_xpath("//div[@id='isst_lat']").text

If you want to use the css then you can do it with

longitude = driver.find_element_by_css_selector('div#isst_lon').text
latitude = driver.find_element_by_xpath('div#isst_lat').text

I have used this method before and it doesn't output anything to the terminal. Do you think its being stored? Or is it just not return anything? – Aug 28 '19 at 04:15

You can use locator by id to get latitude and longitude, like this:

driver = webdriver.Safari()
url = 'http://wsn.spaceflight.esa.int/iss/index_portal.php'
driver.get(url)

WebDriverWait(driver, 20).until(expected_conditions.visibility_of_element_located((By.ID, 'isst_lat')))

latitude = driver.find_element_by_id('isst_lat')
longitude = driver.find_element_by_id('isst_lon')

print(latitude.text)
print(longitude.text)

Following import:

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

The above code I add WebDriverWait until visibility of element located.

To extract the value of Latitude you have to induce WebDriverWait for the visibility_of_element_located() and you can use either of the following Locator Strategies:

Using CSS_SELECTOR:

print(WebDriverWait(driver, 20).until(EC.visibility_of_element_located((By.CSS_SELECTOR, "div.isst_cd#isst_lat"))).get_attribute("innerHTML"))

Using XPATH:

print(WebDriverWait(driver, 20).until(EC.visibility_of_element_located((By.XPATH, "//div[text()='Latitude']//following::div[1]"))).get_attribute("innerHTML"))

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
