Selenium’s Python Module is built to perform automated testing with Python. Selenium Python bindings provide a simple API to write functional/acceptance tests using Selenium WebDriver. After you have installed selenium and checked out – Navigating links using get method, you might want to play more with Selenium Python. After one has opened a page using selenium such as neveropen, one might want to click some buttons automatically or fill a form automatically or any such automated task.
This article revolves around how to grab or locate elements in a webpage using locating strategies of Selenium Web Driver. More specifically, find_element(By.TAG_NAME, ) is discussed in this article. With this strategy, the first element with the given tag name will be returned. If no element has a matching tag name, a NoSuchElementException will be raised.
Syntax –
driver.find_element(By.TAG_NAME, "Tag name")
Example –
For instance, consider this page source:
HTML
< html > < body > < h1 >Welcome</ h1 > < p >Site content goes here.</ p > </ body > < html > |
Now after you have created a driver, you can grab an element using –
login_form = driver.find_element(By.TAG_NAME, 'h1')
How to use driver.find_element(By.TAG_NAME, ) method in Selenium?
Let’s try to practically implement this method and get a element instance for “https://www.geeksforgeeks.org/”. Let’s try to grab first title using its tag “h2”.
Create a file called run.py to demonstrate find_element(By.TAG_NAME) method –
Python3
# Python program to demonstrate # selenium # import webdriver from selenium import webdriver from selenium.webdriver.common.by import By # create webdriver object driver = webdriver.Firefox() # enter keyword to search keyword = "neveropen" # get geeksforgeeks.org # get element element = driver.find_element(By.TAG_NAME, "h2" ) # print complete element print (element) |
Now run using –
Python run.py
First, it will open firefox window with neveropen, and then select the element and print it on terminal as shown below.
Browser Output –
Terminal Output –
