XPATH

1.?绝对路径

2.?相对路径

<input id="kw" name="wd" class="s_ipt" value="" maxlength="255" autocomplete="off">

driver.find_element(By.XPATH, "//input[@id = 'kw']").send_keys("selenium")
driver.find_element(By.XPATH, "//*[@name = 'wd']").clear()
driver.find_element(By.XPATH, "//input[@id = 'kw' and @autocomplete = 'off']").send_keys("selenium")
#? 不局限于id, name，只要是唯一标识属性的值，都可以

3.?通过父元素找下面的子元素

4.?逻辑运算符，多个属性定位元素

driver.find_element(By.XPATH, "//input[@id = 'kw' and @autocomplete = 'off']").send_keys("selenium")

5.?contains()

<span class="bg s_btn_wr">
?? ?<input type="submit" id="su" value="百度一下" class="bg s_btn">
</span>

driver.find_element(By.XPATH, "//span[contains(@class, 's_btn_wr')]/input").click()
driver.find_element(By.XPATH, "//span[@class = 'bg s_btn_wr']/input").click()

6.?text()

<a href="javascript:void(0)" class="login-button" οnclick="login()">登 ?录</a>

driver.find_element(By.XPATH, "//*[text() = '登 ?录']").click()
