How to locate Elements

Take the Baidu text box as an example:

 

<form id="form" name="f" action="/s" class="fm">      <span class="bg s_ipt_wr quickdelete-wrap">           <input id="kw" name="wd" class="s_ipt" value="" maxlength="255" autocomplete="off"></form>

Locate by ID: find_element_by_id ('kw ')

 

Locate by name: find_element_by_name ('wd ')

 

Locate by class: find_element_by_class_name ('s _ ipt ')

 

Locate by TAG: find_element_by_tag_name ('input ')

In practical applications, tags are rarely used to locate an element. tags are generally used to locate a group of elements.

Locate a group of elements based on tags: find_elements_by_tag_name ('input ')

from selenium import webdriverdr = webdriver.Firefox()dr.get("https://www.baidu.com")inputs = dr.find_elements_by_tag_name(‘input‘)for i in inputs:    if i.get_attribute(‘id‘) == "kw":        i.send_keys(‘selenium‘)

 

Locate by text link: find_element_by_link_text ("news ")

When using Chinese, you must declare at the beginning #-*-coding = UTF-8-*-or # Coding = UTF-8

Locate based on some text links: find_element_by_partial_link_text ("new ")

 

Locate by XPath: find_element_by_xpath ('input [@ ID = "kW"] ')

Locate unique elements except ID name class

Find_element_by_xpath ('// input [@ maxlength = "255"]')

Locate by path

Find_element_by_xpath ("// form [@ ID = 'form' and @ class = 'ffm ']/SPAN/input ")

Location Based on absolute path, but it is not recommended if the path may change or the element is deep.

Find_element_by_xpath ("/html/body/Div [2]/Div/form/SPAN/input ")

 

Position Based on CSS:

Common CSS selector syntax

Selector	Description
. Class	Class Selector
# ID	Id Selector
*	Select all elements
Element	Select an element
Element1> element2	Select All 2 elements whose parent element is 1
Element1 + element2	Select All 2 elements next to 1
[Artivity = value]	Select all words whose target is equal to a value.

 

 

 

 

 

 

 

 

 

 

 

E. g:

Find_element_by_css_selector ('. s_ipt ')

Find_element_by_css_selector ('# kW ')

Find_element_by_css_selector ('form. FM> span> input # kW ')

Find_element_by_css_selector ('input [maxlength = "255"] ')
