The eight elements of Selenium

ID element location

• Id: Based on the value of the ID in the element attribute to locate, similar to the ID number on people’s ID card, will not be repeated without accident

  driver.find_element_by_id('id')
  Copy the code

Name element positioning

• Name: Locate based on the value of name in the element attribute, similar to the name on people’s ID cards, which may have duplicate names

  driver.find_element_by_name('name')
  Copy the code

Link Text Element location

• Link text: used to locate hyperlinks

  driver.find_element_by_link_text('registered')
  Copy the code

Partial Link Text Element location

• Partial Link text: Link text Fuzzy query version, similar to link % in the database. If the fuzzy query matches multiple elements that match the adjustment, select the first one

  driver.find_element_by_partial_link_text("Book")
  Copy the code

Classname element location

• Classname: Based on the element class style, it is very easy to encounter duplicates

  driver.find_element_by_class_name("am-btn am-btn-secondary am-btn-xs am-radius")
  Copy the code

Tagname element positioning

• Tagname: Indicates the name of a tag for locating. It has the highest repetition and is used only in the case of secondary filtering after locating

  driver.find_elements_by_tag_name("a")
  Copy the code

Cssselector element location

• Cssselector: Location by absolute path: rarely used this way

  driver.find_element_by_css_selector("body > div.am-g.my-content > div > div.am-u-sm-12.am-u-md-6.am-u-lg-4.container-right > div.forgetpwd-top > a")
  Copy the code

Xpath element location

• Xpath: 1. Location via absolute path, which is rarely used

  driver.find_element_by_xpath("/html/body/div[4]/div/div[2]/div[1]/a")
  Copy the code

• Xpath: 2. Locate based on the relative path in the format of //+ unique parent tag +/ child tag……

  driver.find_element_by_xpath('//form/span/input')
  Copy the code

• Xpath: 3. Locate by element attributes

  # Single attribute positioning
  driver.find_element_by_xpath("//input[@name='pwd']")
  # Multi-attribute positioning
  driver.find_element_by_xpath('//a[@title="Tutorialspoint" and @rel="nofollow"]')
  Copy the code

• Xpath: 4. Locate by element partial attributes

  # start with a partial attribute value
  driver.find_element_by_xpath("//a[starts-with(@title,'Tutorial')]")
  # contains partial attribute values
  driver.find_element_by_xpath("//a[contains(@title,'Tutorial')]")
  driver.find_element_by_xpath("/ / a [contains (text (), 'baidu')]")
  Copy the code

• Xpath: 5. Location by text

  driver.find_element_by_xpath("//span[text()='Login']")
  Copy the code

For the efficiency of these lookup elements, id>name>xpath. Copy Xpath is not recommended because it is inaccurate in web pages. Some elements, whose attribute values change each time the page is refreshed, are called dynamic elements and can only be located in other ways.
