Example usage:
from selenium.webdriver.common.by import By
driver.find_element(By.XPATH, '//button[text()="Some text"]')
driver.find_elements(By.XPATH, '//button')
By class attributes:
ID = "id"
XPATH = "xpath"
LINK_TEXT = "link text"
PARTIAL_LINK_TEXT = "partial link text"
NAME = "name"
TAG_NAME = "tag name"
CLASS_NAME = "class name"
CSS_SELECTOR = "css selector"
1.Locating by Id
Page source:
<html>
<body>
<form id="loginForm">
<input name="username" type="text" />
<input name="password" type="password" />
<input name="continue" type="submit" value="Login" />
</form>
</body>
<html>
login_form = driver.find_element_by_id('loginForm')
2.Locating by Name
Page source:
<html>
<body>
<form id="loginForm">
<input name="username" type="text" />
<input name="password" type="password" />
<input name="continue" type="submit" value="Login" />
<input name="continue" type="button" value="Clear" />
</form>
</body>
<html>
username = driver.find_element_by_name('username')
password = driver.find_element_by_name('password')
continue = driver.find_element_by_name('continue') //"Login" button,it occures before the "Clear" button
3.Locating by XPath
Page source:
<html>
<body>
<form id="loginForm">
<input name="username" type="text" />
<input name="password" type="password" />
<input name="continue" type="submit" value="Login" />
<input name="continue" type="button" value="Clear" />
</form>
</body>
<html>
//locating form
login_form = driver.find_element_by_xpath("/html/body/form[1]")
login_form = driver.find_element_by_xpath("//form[1]")
login_form = driver.find_element_by_xpath("//form[@id='loginForm']")
//locating username
username = driver.find_element_by_xpath("//form[input/@name='username']")
username = driver.find_element_by_xpath("//form[@id='loginForm']/input[1]")
username = driver.find_element_by_xpath("//input[@name='username']")
//locating "Clear"
clear_button = driver.find_element_by_xpath("//input[@name='continue'][@type='button']")
clear_button = driver.find_element_by_xpath("//form[@id='loginForm']/input[4]")
4.Locating Hyperlinks by Link Text
Page source:
<html>
<body>
<p>Are you sure you want to do this?</p>
<a href="continue.html">Continue</a>
<a href="cancel.html">Cancel</a>
</body>
<html>
continue_link = driver.find_element_by_link_text('Continue')
continue_link = driver.find_element_by_partial_link_text('Conti')
5.Locating Elements by Tag Name
Page source:
<html>
<body>
<h1>Welcome</h1>
<p>Site content goes here.</p>
</body>
<html>
heading1 = driver.find_element_by_tag_name('h1')
6.Locating Elements by Class Name
Page source:
<html>
<body>
<p class="content">Site content goes here.</p>
</body>
<html>
content = driver.find_element_by_class_name('content') //Locating "p" element
7.Locating Elements by CSS Selectors
Page source:
<html>
<body>
<p class="content">Site content goes here.</p>
</body>
<html>
content = driver.find_element_by_css_selector('p.content') ////Locating "p" element
