How to use regular expressions in css in Selenium with python?
We can identify elements by matching its attributes partially with the help of regular expressions. In css, there are multiple methods to achieve this. They are listed below −
Using the wild character *. This means the string contains our given text.
Syntax−
driver.find_element_by_css_selector("input[name*='sel']")
It will search the input tag which contains the 'name' attribute containing 'sel' text.
Using the wild character ^. This means the string starts with our given text.
Syntax−
driver.find_element_by_css_selector("input[name^='Tut']")
It will search the input tag which contains the 'name' attribute starting with 'Tut' text.
Using the wild character $. This means the string ends with our given text.
Syntax−
driver.find_element_by_css_selector("input[name$='nium']")
It will search the input tag which contains the 'name' attribute ending with 'nium' text.
Example
Code Implementation with * wild character in CSS.
from selenium import webdriver #browser exposes an executable file #Through Selenium test we will invoke the executable file which will then #invoke actual browser driver = webdriver.Chrome(executable_path="C:\chromedriver.exe") # to maximize the browser window driver.maximize_window() #get method to launch the URL driver.get("https://www.tutorialspoint.com/index.htm") #to refresh the browser driver.refresh() # identifying the edit box with the help of * in css selector driver. find_element_by_css_selector("input[id*='sc-i']"). send_keys("Selenium") #to close the browser driver.close()
Code Implementation with ^ wild character in css.
from selenium import webdriver #browser exposes an executable file #Through Selenium test we will invoke the executable file which will then #invoke actual browser driver = webdriver.Chrome(executable_path="C:\chromedriver.exe") # to maximize the browser window driver.maximize_window() #get method to launch the URL driver.get("https://www.tutorialspoint.com/index.htm") #to refresh the browser driver.refresh() # identifying the edit box with the help of ^ in css selector driver. find_element_by_css_selector("input[id^='gsc']"). send_keys("Selenium") #to close the browser driver.close()
Code Implementation with $ wild character in css.
from selenium import webdriver #browser exposes an executable file #Through Selenium test we will invoke the executable file which will then #invoke actual browser driver = webdriver.Chrome(executable_path="C:\chromedriver.exe") # to maximize the browser window driver.maximize_window() #get method to launch the URL driver.get("https://www.tutorialspoint.com/index.htm") #to refresh the browser driver.refresh() # identifying the edit box with the help of $ in css selector driver. find_element_by_css_selector("input[id$='id1']"). send_keys("Selenium") #to close the browser driver.close()
