Question

我试图通过一个网页中所载的几个清单项目进行周期。我似乎无法成功地解脱这些因素。 I m试图打字的成分被界定为这样,网页上有4个:

<div data-test-component=“StencilReactView”=“listitem”类别=“cs-1uk1gs8”>

I m using the following in an attempt to fetch these elements (using Python): driver.find_elements(By.XPATH, "//div[@role= listitem ]")

一旦我能够成功掌握这一要素,我就能够按我的需要,通过这些要素进行循环,但我似乎无法成功掌握。任何帮助都将受到高度赞赏。

我尝试通过XPATH和按班级挑选这个要素,但没有成功。

Answer 1

鉴于超文本:

<div data-test-component="StencilReactView" role="listitem" class="css-1uk1gs8">

这些要素似乎是动态因素。

摘录:https://stackoverflow.com/a/64770041/7429447>>>>>>visibility_of_all_elements_ place_<><>>>>> • 定位器战略:

使用CSS_SlectTOR:

elements = WebDriverWait(driver, 20).until(EC.visibility_of_all_elements_located((By.CSS_SELECTOR, "td.entity-name")))

使用XPATH:

elements = WebDriverWait(driver, 20).until(EC.visibility_of_all_elements_located((By.XPATH, "//div[@role= listitem ]")))

from selenium.webdriver.support.ui import WebDriverWait

from selenium.webdriver.support import expected_conditions as EC

Answer 2

或许,如果你要使用全部xpath来确定元素,就是指bsxpath
。

abs-xpath as this /html/one/div[3]/div/div/div/div/div/form/input, which from the 网站

您应制定这样的守则:

driver.find_element(By.XPATH, r"/html/body/div[3]/div/div/div/div/div[2]/form/input")
WebDriverWait(driver, timeout=10).until(EC.element_to_be_clickable((By.XPATH, r"/html/body/div[3]/div/div/div/div/div[2]/form/div[2]/div[2]/button")))
driver.find_element(By.XPATH, "/html/body/div[3]/div/div/div/div/div[2]/form/div[2]/div[2]/button").click()

<>strong>besides, 您可使用另一种方法查找元素,如:

driver.find_elements(By.CLASS_NAME, "username-input")[0]
driver.find_elements(By.TAG_NAME,  a )[0]
driver.find_elements(By.ID,  userSkin )[0]

the last, maybe you should use EC.* of selenium to wait for something happen you click and html reload, then some element can be located like login or logout some website, you should wait until page reload and some element can be located.

from selenium.webdriver.support.wait import WebDriverWait
from selenium.webdriver.common.by import By
from selenium.webdriver.support import expected_conditions as EC
WebDriverWait(driver, timeout=10).until(EC.element_to_be_clickable((By.XPATH, r"")))
WebDriverWait(driver, timeout=10).until(EC.visibility_of_all_elements_located((By.XPATH, r"")))
WebDriverWait(driver, timeout=10).until(EC.presence_of_element_located((By.XPATH, r"")))
WebDriverWait(driver, timeout=10).until(EC.title_contains((By.XPATH, r"")))
WebDriverWait(driver, timeout=10).until(EC.text_to_be_present_in_element((By.XPATH, r"")))
