该页面需要时间才能完全加载，因此您无法获得您想要的值。获取所有邮政编码 Induce WebDriverWait() 和 wait for visibility_of_all_elements_located()要从元素中获取最后一个子元素，您可以诱导 javascript 执行程序或分割线来获取唯一的邮政编码。driver.get("https://www.craispesaonline.it/provincia/treviso")search=WebDriverWait(driver,20).until(EC.visibility_of_all_elements_located((By.XPATH,'//address//p[@class="text-lowercase m-0 ng-binding"]')))for postcode in search:    print(driver.execute_script('return arguments[0].lastChild.textContent;', postcode))您需要导入以下库。from selenium.webdriver.support.ui import WebDriverWaitfrom selenium.webdriver.support import expected_conditions as ECfrom selenium.webdriver.common.by import By控制台输出：0422/710092 0422 452388 0422/958833 0423/689003 0422/853881 0422/969047 0423/564126 0423/650073 0423/723434 0423/942150 0438/500484 0423/868496 0438/898282 0483801679 0422/832603 0423/470063 0423/755164-23 0438/492409 0438/893369 0422/791529 0423/302959 0423/301381 0423-603754 0423/609936 0423/609151 0423480340 0438/781107 0423/670593 0423/81743 0423/81534 0423/972091 0423/451941 0422/912384 0423/620803 0423/621383使用splitlines()的相同输出driver.get("https://www.craispesaonline.it/provincia/treviso")search=WebDriverWait(driver,20).until(EC.visibility_of_all_elements_located((By.XPATH,'//address//p[@class="text-lowercase m-0 ng-binding"]')))for postcode in search:    print(postcode.text.splitlines()[-1].split("|")[-1].strip()) #last element which is postcode

要完成前面的答案，您可以使用一个 XPath 表达式获取可以送货的商店的邮政编码：//div[@class="row province-cms-content-store-row ng-scope"][./div[@ng-if="store.shippingEnabled == true"]]//meta[@itemprop="postalCode"]/@content硒代码：driver.get("https://www.craispesaonline.it/provincia/treviso")postcodes = WebDriverWait(driver,20).until(EC.visibility_of_all_elements_located((By.XPATH,'//div[@class="row province-cms-content-store-row ng-scope"][./div[@ng-if="store.shippingEnabled == true"]]//meta[@itemprop="postalCode"]'))).get_attribute("content")输出：29个邮政编码['31038']['31038']['31047']['31050']['31030']...

Answer 3

要仅提取可以送货的商店的邮政编码，您可以诱导WebDriverWait并且visibility_of_all_elements_located()您可以使用以下内容xpath基于定位策略：使用CSS_SELECTOR：driver.get("https://www.craispesaonline.it/provincia/treviso")WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.XPATH, "//a[@class='cl-accept']"))).click()driver.execute_script("return arguments[0].scrollIntoView(true);", WebDriverWait(driver, 20).until(EC.visibility_of_element_located((By.XPATH, "//h2[contains(., 'Potrai scegliere di ricevere la tua spesa in due modi:')]"))))addresses = [my_elem.text for my_elem in WebDriverWait(driver, 20).until(EC.visibility_of_all_elements_located((By.XPATH, "//input[@value='Consegna']//preceding::address[1]//p[@class='text-lowercase m-0 ng-binding']")))]for address in addresses:    print(re.findall(r"\b\d{5}\b", address))控制台输出：['31038']['31038']['31047']['31050']['31030']['31031']['31034']['31014']['31035']['31010']['31010']['31036']['31037']['31037']['31050']['31050']['31044']['31044']['31044']['31044']['31044']['31023']['31058']['31040', '81743']['31049']['31050']['31020']['31040']['31040']注意：您必须添加以下导入：from selenium.webdriver.support.ui import WebDriverWaitfrom selenium.webdriver.common.by import Byfrom selenium.webdriver.support import expected_conditions as EC
