在网页上,此元素是唯一包含确切文字“ Volgende stap”的元素:
<span class="b-button--label ng-binding ng-scope" ng-if="arrowDirection === 'right'">Volgende stap</span>
但是当我尝试使用xpath选择包含这些单词的元素(列表)时:
driver.find_elements_by_xpath("//span[contains(text(),'Volgende')]")
driver.find_elements_by_xpath("//span[.='Volgende stap']")
driver.find_elements_by_xpath("//span[text()='Volgende stap']")
我不断收到一个空列表(如果是element not found
而不是find_element
,则为find_elements
。
这是通往我正在处理的html页面的脚本:
from selenium import webdriver
from selenium.webdriver.common.keys import Keys
from selenium.webdriver.support import expected_conditions as EC
from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import WebDriverWait as wait
driver = webdriver.Chrome()
driver.get("https://www.greetz.nl/kaarten/verjaardag/man")
wait(driver, 10).until(EC.element_to_be_clickable((By.CSS_SELECTOR, "a[href*='/kaart/detail/greetz-verjaardagskaart---abracadabra/1142778148']"))).click()
wait(driver, 10).until(EC.element_to_be_clickable((By.XPATH, "//span[text()='Kaart bewerken']"))).click()

它位于iframe中。首先切换到它,然后尝试通过文本查找:
frame = driver.find_element_by_css_selector('frame.personalize--frame')
driver.switch_to.frame(frame)

您可以使用以下解决方案:
使用CSS_SELECTOR
:
WebDriverWait(driver, 10).until(EC.frame_to_be_available_and_switch_to_it((By.CSS_SELECTOR,"iframe.personalize--frame[src='//www.greetz.nl/editor/desktop.html']")))
WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.CSS_SELECTOR, "span.b-button--label.ng-binding.ng-scope[ng-if*='right'][]"))).click()
使用XPATH
:
WebDriverWait(driver, 10).until(EC.frame_to_be_available_and_switch_to_it((By.XPATH,"//iframe[@class='personalize--frame' and @src='//www.greetz.nl/editor/desktop.html']")))
WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.XPATH, "//span[@class='b-button--label ng-binding ng-scope' and contains(text(),'Volgende')]"))).click()
注意:您必须添加以下导入:
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.common.by import By
from selenium.webdriver.support import expected_conditions as EC
